As a PhD chemist with many years of laboratory experience, Dr. Florian Heinrich has spent numerous hours working with rotary evaporators. One thing has become clear: the right vacuum is crucial for a successful process. In this article, he shares his practical insights for efficient and safe work with the rotary evaporator.

Are you familiar with the problem that your pump creates a vacuum even though the stop button is activated? A simple solution may be to clean the electromagnetic in-line solenoid valve. This is because porous hose material or dirt from the application can sometimes build up on the valve seal. You can regain control of your vacuum control with…

The final step of connecting the vacuum pump to the laboratory device is about having the right connectors. This requires connecting parts such as small flanges and tubings. When selecting them, it is important to consider their functions, connection sizes and materials. Read our article for information and tips on how the right connecting parts…

There is a vacuum pump that is best-suited to the needs of every laboratory. But how do users find the right one for their diverse applications? The Vacuum Pump Selection Guide helps them to choose the perfect pump.

Laboratory processes are only successful if important process conditions, such as the required process pressure, are achieved. The most important indication for the proper function of a vacuum pump is its ability to reach its specified final pressure, or ultimate vacuum. This can be determined with a calibrated gauge to measure the pump’s ultimate…

Vacuum pumps should reliably support important processes in the background and take up as little of your time as possible for maintenance. We explain how to change diaphragms and valves using the example of the MD 1C chemistry diaphragm pump. Apart from wear parts, the diaphragm pump runs maintenance-free under normal load. All bearings are…
