Laboratory Vacuum Systems LVS, Welch Vacuum

Chemical resistant laboratory vacuum systems

The LVS laboratory vacuum systems are compact pump systems for conventional vacuum distillation. Equipped with a chemical-resistant diaphragm pump they are the ideal solution for numerous applications in chemical laboratories and in research.
According to the application, our LVS models can be supplied with or without vacuum control. Three control philosophies are available, the standard version being a chemically resistant solenoid valve with two point control. Operation of the controller has been simplified so that it is easy to learn and can also be performed from a PC.
Our LVS systems are available with many different features and in numerous versions, enabling them to be adapted without difficulty to countless applications.
Your safety is important for us. All components of our pump systems which come into contact with gas are made of high-grade, chemically resistant material. This means that they can even be used to evacuate solvent and acid vapors.
Glassware is coated with a clear plastic layer, through which the process can be observed at all times. The high-pressure side of the cooler is insulated.
