Vacuum Pump

A vacuum pump is a piece of scientific apparatus that removes gas particles from an airtight container or volume in order to leave behind a partial vacuum. Vacuum pumps are mostly used with lyphilizers and evaporation machines. Marshall Scientific sells an array of notable pump brands that include: Buchi, Precision, Gast, Welch, Alcatel, Edwards, Savant, and Labconco. We have an assortment of different powered vacuum pumps that are suitable for any lab setting.
