Vacuum systems for the chemical laboratory

Modern vacuum systems have significant advantages over longtime used systems such as water-jet and oil-sealed rotary-vane pumps in the chemical laboratory. The modern diaphragm pumps are oil-free and are made from materials with high chemical resistance. They are easy to maintain and they are environmentally friendly. For a wide range of applications they offer an optimum in performance and efficiency.
In recent decades vacuum technology has gained considerably in importance in all areas of science and industry. Nearly all products of our daily life are treated under vacuum conditions during their development and/or manufacturing. Many products, like light bulbs, television sets, semiconductors, and also freezedried materials and pure pharmaceuticals are inconceivable without vacuum technology. In the chemical laboratory, vacuum is essential for the separation or processing of reaction products in a controlled and energy-saving way. For example, distillations are typically run under vacuum to lower the boiling temperature. Hence, temperature sensitive products can be processed without being damaged. Usually, in chemical applications large quantities of substances are evaporated, generating huge amounts of vapors, which are often corrosive or hazardous. Therefore, special care has to be taken to protect bot pumping systems and the environment.
