Rotary vane vacuum pump for freeze drying

Freeze drying
Freeze drying, also known as freeze drying, is a particularly mild drying process and is therefore suitable for sensitive products. In pharmaceuticals and biotechnology, lyophilized substances include temperature-sensitive vaccines, antibiotics and bacteria. Dry them directly in a glass bottle or syringe and store them in a few seconds if needed. The purity and sterility of the system are particularly required when drying injectable products. For this purpose, vacuum provides support not only for the cleaning of vacuum products, but also for the monitoring of drying chamber.

Vacuum requirement
For freeze-drying, the pressure must be below the triple point of the solvent (e.g. water) used. In addition, unwanted substances such as oxygen are removed from the drying chamber during the vacuum. Although the working pressure during primary drying is usually between 0.5 hPa and 1*10-2 hPa, it can be as high as 1*10-3 hPa during secondary drying or during regulation in the drying chamber.

Product portfolio

Vacuum offers a comprehensive portfolio of freeze-drying products, including vacuum pumps for vacuum pumping, pressure gauges and calibration pump stations, gas analysis mass spectrometers for process monitoring, and leak detectors for leak location.
