The Microsart® maxi.vac and Microsart® mini.vac vacuum pump series provide the latest technology for routine use in a microbiology laboratory. These are neoprene diaphragm electrical pumps that are therefore oil and maintenance free at low noise levels. The vacuum applied by the new pumps can be controlled and easily adapted to your given specifications at any time. This ensures that stressed microorganisms (e.g., bacteria) are gently concentrated on the membrane filter surface. This leads to lower mortality, which in turn leads to higher recovery rates and shorter incubation times.
