节省资源和时间

特性

  • 由于自动蒸馏 AutoDist 功能,测量不受设备内温差的影响。该功能可识别冷凝过程的开始,并可在单独的测量中自动调整蒸馏开始时间。这通过冷凝容器内的内置温度传感器实现,并使结果的可重现性更佳。

  • 冷却水控制通过智能流量限制自动节水。蒸汽蒸馏开始后,水开始流经冷凝器并收集馏出液。蒸馏前后,装置会自动关闭冷却水阀。此功能可在测定过程中节省大约 20% 的水,并消除对供水的担忧。

  • 使用我们的多功能组件,您可以轻松升级和自动化您的系统,以实现最大的便利。所有部件都可以单独选择,也可以接连组合在一起。模块化设计使您能够实现功能的最佳组合,以满足您的个性化需求。通过这种方式,您可以根据个人需要获得功能和外围设备的最佳组合。

  • 得益于创新的传感器技术,凯氏定氮产品系列仪器可将用户接触到的风险降至最低限度。安全传感器监控冷却水流量、蒸汽发生器压力以及样品管是否正确放置。水箱液位传感器可检测水、废液和试剂液位。安全屏障完全透明,并配备安全控制传感器。如果在操作过程中打开安全屏障,该过程将自动停止。蒸汽动力可调节 (10 – 100%),蒸汽梯度可编程设定以处理发泡样品。

  • 在实验室中,电源电压的偏差可能高达原始值的 10%。这可能会影响蒸 汽动力输出。为了避免这些偏差,集成了稳压器以维持所需的电源电 压。这提高了测量准确度并确保每个结果的最高重现性。

  • For more convenience and easier sample handling, we offer configurations with sample tube and receiver waste aspiration. This saves time and allows for smooth operation of the instrument.

  • Automated titration is key to achieving the highest performance possible in Kjeldahl protein determination. Titration dosage, as well as endpoint recognition via suitable electrodes, is carried out automatically. This allows for minimum user interaction and high throughput at the same time.

  • The OnLevel sensor is available for all configurations where no titration vessel is mounted. The sensor stops the distillation automatically after a defined condensate volume is reached. The sensor can be easily set and adjusted manually via a magnetic backplate. Obtain reproducible condensate volumes independent of the system lifetime.

  • The reaction detection sensor is available for MultiKjel configurations. It can save up to 30 % of NaOH reagent solution for the alkalization process so that you can work more cost-efficiently and environmentally friendly.

  • The intuitive touch screen provides fast feedback and enables easy process handling

  • Glass and plastic splash protectors are available. Glass splash protectors enable you to monitor the process to support method development and optimization. Plastic splash protectors are more robust and durable. Depending on the application, different splash protector variants enable the best performance
