Extendable

Seamless plug & play integration into:
- A speed-controlled vacuum system with Interface I-300 / I-300 Pro
- A fully automated BUCHI Rotavapor® R-300 system including all process parameters

Features

Reduce noise levels

Thanks to speed-control, the pump operates smoothly to maintain the set vacuum. This results in very low noise emission (as low as 32 dB) and a more comfortable working environment.

Directly see the condensation status

Condensed solvents or particles are easily visible thanks to a transparent inspection window, facilitating maintenance.

Protect yourself and the environment

A secondary condenser prevents solvent sucked into the vacuum pump from release into the environment. This condenser is beneficial for cases where low boiling solvents are used or when pressure values are set too aggressive.

Save energy

When not connected to the interface, the pump automatically switches to power savings mode after a given time interval has passed. This leads to substantial energy and cost savings.

Decrease contamination

The Woulff bottle captures contaminants from entering the system. This increases the lifetime of the system.

Eliminate bumping

When connected to the interface, the speed control mode of the Vacuum Pump ensures pressure levels are held uniformly. This not only minimizes the risk of bumping, it also reduces noise emission significantly and extends the lifetime of the pump.

Expert Advice

How can I reduce the noise emission of a vacuum pump?

Read more about How can I reduce the noise emission of a vacuum pump?

By choosing a speed-controller pump. The Vacuum Pump V-300 / V-710* in conjunction with the Interface I-300 / I-300 Pro are operating only when required. This significantly reduces the noice emission and extends the lifetime of the pump.

*V-710 reqires the LegacyBox for speed-controlled operation.

What is the advantage of the secondary condenser compared to an in-line condenser between pump and distillation unit?

Read more about What is the advantage of the secondary condenser compared to an in-line condenser between pump and distillation unit?

If the solvent is expanded first to ambient pressure, the vapor pressure is increased and thus a condensation much more efficient. This is the reason why the secondary condenser is at the pressure side of the pump. Due to the chemical resistance of the diaphragm pump, even aggressive gases and vapors do not harm the pump.

How do I efficiently use the gas ballast?

Read more about How do I efficiently use the gas ballast?

The gas ballast is an easy method to adjust leakage air to the pump heads. This addition of inert gas helps to dry the diaphragms in case of condensate and thus increase the pump rate again. Typically, the gas ballast is closed to obtain highest flow rate.

How can I reset the power save mode?

Read more about How can I reset the power save mode?

The power save mode mode can be reset by simply switching the pump off and on again.

Is the final vacuum affected by the power save mode?

Read more about Is the final vacuum affected by the power save mode?

No, the final vacuum is not affected by the power save ode only reduces the speed of the pump which reduces the capacity after 1 hour to 1.6 m3/h and after 2 hour to 1.0 m3/h.

Why are there some condensate droplets on the diaphragm?

Read more about Why are there some condensate droplets on the diaphragm?

If the distillation parameters are not chosen according to the "delta 20 rule" (10-30-50), the condensation is not complete and vapor is entering into the pump. Due to the high vacuum in the second stage, the vapor may condensate, leading to droplets. Thus, the pressure has to be increased or the cooling temperature of the condensation assembly decreased.
