Product Description
Dependable vacuum is at the heart of evaporation, filtration, drying and degassing. VACUUBRAND pumps are engineered in Germany for long service life, low noise and efficient operation in the laboratory.
The VACUUBRAND 20738153 is the version of the MV 2 VARIO select Diaphragm pump, 100-120 V, 50-60 Hz. Chemistry-resistant models use fluoroplastic flow paths for corrosive vapors, and VARIO models adjust motor speed automatically to the process for faster, cleaner results. LIGHT LABS supplies genuine VACUUBRAND products with knowledgeable support from our Englewood, Colorado team.
