Privacy Policy

Data protection has a particularly high priority for BUCHI. It is possible to use the BUCHI website without providing any personal data. If a data subject wants to use special services of our enterprise via our website, processing of personal data could become necessary. If processing of personal data is necessary, this will only be done on the basis of legal regulations or your consent and solely for the purposes for which the data was collected or transmitted to us.

The processing of personal data, such as the name, address, e-mail address, or telephone number of a data subject shall always be in line with the EU General Data Protection Regulation (GDPR), and in accordance with the country-specific data protection regulations applicable to BUCHI.

In this Privacy Policy, our company would like to inform the public about the nature, scope and purpose of the personal data we collect, use and process. Furthermore, data subjects are informed of their rights in this Privacy Policy.

As the controller, BUCHI has implemented numerous technical and organizational measures to ensure the most complete protection of personal data processed through this website. Nevertheless, Internet-based data transmissions can have security gaps, so that absolute protection cannot be guaranteed. For this reason, every data subject is free to transmit personal data to us by alternative means, for example by telephone.

This Privacy Policy applies to all websites and web services provided and operated by the controller Büchi Labortechnik AG, Meierseggstrasse 40, 9230 Flawil (Switzerland). 
This applies in particular to the websites (hereinafter also referred to as ”our website“ or ”our site” or with “we”, “us” or “our”).

In addition to our online offering, we provide free mobile apps that you can download to your mobile device. In no. 12, we therefore provide additional information on the collection of personal data when using our "BUCHI" mobile apps (hereinafter referred to as "apps").

This Privacy Policy together with the Terms of Use form the basis for the processing of personal data. Please read this policy carefully before using our website.

f) Pseudonymization

Pseudonymization is the processing of personal data in such a way that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separate and is subject to technical and organizational measures to ensure that the personal data is not attributed to an identified or identifiable natural person.

  • Website from which the request comes
  • Browser used
  • Language and version of the browser software

  • ensure the long-term functionality of our information technology systems and the technology of our website, and
  • provide law enforcement authorities with the information necessary for prosecution in the event of a cyberattack. 

Therefore, BUCHI analyzes anonymously collected data and information on one hand for statistical purposes and on the other for the purpose of increasing the data protection and data security of our enterprise, with the aim of ensuring an optimal level of protection for the personal data we process.
The anonymous data of the server log files is stored separately from any personal data provided by a data subject. The legal basis for data processing is Art. 6 para. 1 s. 1 let. b and let. f GDPR. Our legitimate interest follows from the aforementioned purposes for data collection.

In addition, we use cookies as well as analytics services and social media bookmarks / plug-ins when you visit our website and use our apps.

When you contact us via a contact form or by e-mail, the data you provide (e-mail address, name, telephone number, address and information provided by you in the contact form) will be stored by us in order to answer your questions. If required by your request, the data may also be transmitted to companies affiliated with BUCHI or to market organizations and processed by them. 
Data processing for the purpose of contacting us via our contact form is based on your voluntarily given consent according to Art. 6 para. 1 s. 1 let. a GDPR. If you contact us by e-mail, the data processing is based on our legitimate interest according to Art. 6 para. 1 s. 1 let. f GDPR.

If you have also consented to the use of your data for the sending of newsletters and other marketing and advertising-related e-mails, we process the data for direct marketing purposes and link it to other information that BUCHI has stored about you in a customer profile. The legal basis for this is Art. 6 para. 1 s. 1 let. a GDPR.

4. Use of service providers, transfer of data to third parties

BUCHI uses selected external service providers to provide support and administrative tasks for our website or apps. These service providers may occasionally have access to your personal data.

Cookie list

A cookie is a small piece of data (text file) that your browser stores on your device when instructed by a website you visit to "remember" information about you, such as your language preferences or login information. These cookies are set by us and are called first-party cookies. We also use third-party cookies, which come from a different domain than the one of the website you are visiting. We use these cookies to support our advertising and marketing efforts. In particular, we use cookies and other tracker technologies for the following purposes:

These cookies are necessary for the website to function and cannot be disabled in your systems. Typically, these cookies are set only in response to actions you take that correspond to a service request, such as setting your privacy preferences, logging in, or filling out forms. You can set your browser to block these cookies or to notify you about these cookies. However, some areas of the website will not work in this case. These cookies do not store any personal data.

With these cookies, the website is able to provide advanced functionality and personalization. They may be set by us or by third parties whose services we use on our site. If you do not allow these cookies, some or all of these services may not function properly.

Performance cookies

These cookies allow us to count visits and traffic sources so that we can measure and improve the performance of our website. They help us answer questions about which pages are most popular, which are least used, and how visitors move around our site. All information collected by these cookies is aggregated and therefore anonymous. If you do not allow these cookies, we will not be able to know when you visited our website.

Cookies for marketing purposes

These cookies may be set via our website by our advertising partners. They may be used by these companies to profile your interests and show you relevant ads on other websites. They do not directly store personal information, but are based on a unique identification of your browser and Internet device. If you do not allow these cookies, you will receive less targeted advertising on the web.

Tracking pixels

Tracking pixels are small graphic files embedded in websites or emails. Tracking pixels may be used to communicate with cookies, count visitors to a website, and understand usage habits. Tracking pixels may also be included in e-mails to learn whether messages have been opened, edited, or forwarded. You can prevent information from being collected in this way through tracking pixels; to do this, you must block cookies as described above under ”Cookies”.

6. Web and apps analysis

Google Analytics

Our websites use Google Analytics, a web analytics service provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google“). By using Google Analytics, we want to ensure the needs-oriented design and ongoing optimization of our website as well as statistically record the use of our website in order to optimize our offer for you. The legal basis for this is Art. 6 para. 1 s. 1 let. f GDPR.
Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website is usually transmitted to a Google server and stored there. Our websites use Google Analytics with the extension “_anonymizeIp()”. This means that IP addresses are processed in abbreviated form, which means that they cannot be traced back to a specific person. Insofar as the data collected about you has a personal reference, this is therefore immediately excluded, and the personal data is thus immediately deleted. Google maintains data centers worldwide (inside and outside the EU, USA). We do not know whether your data may also be transmitted by Google to servers outside the EU and USA.

On our behalf, Google will use this information for the purpose of evaluating your use of our website, compiling reports on website activity and providing other services relating to website activity and Internet usage to the website operator (e.g., display advertising features such as remarketing, Google Display Network impression reports, DoubleClick Campaign Manager integration or Google Analytics reports on performance according to demographic characteristics and interests).

Under certain circumstances, Google may analyze your usage behavior across several end devices (PC, smartphone, tablet, etc.) by means of so-called cross-device functions and evaluate them for BUCHI. For this purpose, Google may link information generated via the respective end devices with each other and with data from your Google account for the purpose of personalized advertising, if you have a Google account and your settings there are such that Google can link your browser history with your Google account and that information from your Google account can be used to personalize advertisements.

You may decline the use of cookies by selecting the appropriate settings on your browser; however, please note that if you do this you may not be able to use the full functionality of this website. You can also prevent the collection of data generated by the cookie and related to your use of our website (including your IP address) to Google and the processing of this data by Google by downloading and installing the browser plug-in available at the following link:

As an alternative to the browser plug-in or within browsers on mobile devices, you can set an opt-out cookie that will prevent Google Analytics from collecting data within this website in the future (this opt-out cookie only works in this browser and only for this domain, so if you delete your cookies in this browser, you must click this link again).

Google AdWords Conversion Tracking

In addition, our websites use Google AdWords Conversion Tracking, a web analytics service provided by Google. The legal basis for this is Art. 6 para. 1 s. 1 let. f GDPR.

The conversion tracking cookie is set when a user clicks on an ad placed by Google. These cookies lose their validity after 30 days and are not used for personal identification. If you visit certain pages of our website within these 30 days, Google and we can recognize that you have clicked on the ad and have been redirected to this page. Each Google AdWords customer receives a different cookie. Cookies can therefore not be tracked through the websites of AdWords customers. The information collected using the conversion cookie is used to create conversion statistics for us. We learn the total number of users who clicked on our ad and were redirected to our site. However, we do not receive any information that personally identifies you. Google maintains data centers worldwide (inside and outside the EU, USA). We do not know whether your data may also be transmitted by Google to servers outside the EU and USA.

If you do not wish to participate in this tracking, you can easily deactivate the Google Conversion Tracking cookie via your Internet browser under User Settings. They will then not be included in the conversion tracking statistics. You can find further setting options on the page for deactivating Google advertising at

The information provided under no. 6. "Google Analytics" regarding the third-party provider Google apply accordingly.

Google AdWords Remarketing 

In addition to Adwords Conversion Tracking, we use the Google Remarketing application from Google. This is another procedure we use for reaching out to you. Through this application, our advertisements can be displayed to you during your subsequent Internet use after visiting our website. This is done by means of cookies stored in your browser, via which your usage behavior is recorded and evaluated by Google when you visit various websites. This allows Google to determine your previous visit to our website. According to its own statements, Google does not combine the data collected in the course of remarketing with your personal data that may be being stored by Google. In particular, according to Google, pseudonymization is used in remarketing.

The legal basis for the use of Google AdWords Remarketing is Art. 6 para. 1 s. 1 let. f GDPR. The underlying promotional purpose is to be considered a legitimate interest within the meaning of the GDPR.

The information provided under "Google Analytics" regarding the third-party provider Google applies accordingly.

Yahoo!Japan Ad Retargeting

At BUCHI, Yahoo Inc. may acquire and/or use your visit/activity history information from our website. During this procedure, our advertisements can be displayed to you during subsequent Internet use after visiting our website. This is achieved by means of cookies stored in your browser, which are used by Yahoo Inc. to record and evaluate your usage behavior when you visit different websites. Your visit/activity history information acquired by the third party is handled in compliance with third party’s privacy policy. You can can opt-out of the use of your visit/activity history information to ad delivery by following the steps outlined in BUCHI Labortechnik’s privacy policy.

Google Tag Manager

BUCHI uses the Google Tag Manager, a service provided by Google. This service allows website tags (tags are small code elements on websites that are used, among other things, to measure traffic and visitor behavior) to be managed through one interface. The Google Tag Manager itself (which implements the individual tags) is a cookie-less domain. Personal data is not collected by the Google Tag Manager. It merely ensures that other tags are triggered, which in turn may collect data. However, Google Tag Manager does not access this data. If a deactivation has been made at the domain or cookie level, this remains in place for all tracking tags implemented with Google Tag Manager.

The information provided under "Google Analytics" regarding the third-party provider Google applies accordingly. Inc.

BUCHI uses the Salesforce Marketing Cloud of, Inc, Salesforce Tower, 415 Mission Street, 3rd Floor, San Francisco, CA 94105, USA. Salesforce Marketing Cloud uses cookies to analyze user behavior on our websites and apps. By using the Salesforce Marketing Cloud, we want to analyze which of our websites/apps are visited by users and which products users are interested in, in order to be able to present our users with content tailored to their needs, as well as for direct advertising purposes. The data resulting from the analysis of user behavior is collected anonymously or, if possible, in user profiles. The evaluation of user behavior can be performed by an algorithm or manually.

For the evaluation of user behavior, information about the website or app usage is linked with an individually generated customer ID and, if applicable, with other data, with information about actions performed by the user on our websites or apps, with the data mentioned in section 3,  and with other data that may already be stored in a customer profile about the respective user. User behavior is recorded and evaluated in a user profile if consent has been given to receive advertising and information material. If such consent is not given, the cookie only records anonymized data of the user.
The use of, Inc. services may result in, Inc. having access to your personal data., Inc. processes your data exclusively on behalf of and at the instruction of BUCHI. For information about the Salesforce Privacy Policy and data processing, please visit The collected data is stored on servers of, Inc.
You can disable cookies at any time, but this may result in the website or apps no longer being fully usable. Alternatively, you can opt-out. In this case, Inc. deletes all existing cookies and attempts to set a new cookie (no-tracking cookie) so that the objection is preserved for future visits to the website or app. The no-track cookie tells the server not to create any user analytics for you in the future. If your browser is set to generally not accept cookies, a no-track cookie cannot be set. In addition, if you delete your cookies, use a different computer or a different web browser, you will need to perform the opt-out process again.
The legal basis for this is Art. 6 para. 1 s. 1 let. a GDPR, if and insofar as consent has been given, otherwise Art. 6 para. 1 s. 1 let. f GDPR.


BUCHI uses the Showpad sales promotion system from Showpad, Moutstraat 62, 9000 Ghent, Belgium, which measures the behavior of specific individuals in contact with BUCHI, e.g., during a customer or consultation meeting, and makes reports available to the sales organization.
