Product Overview
The HM-WX6B+ from HM Instruments uses negative-pressure membrane filtration to collect microorganisms from suitable liquid samples. Retained microorganisms are cultured and counted after filtration as part of a microbial limit test; the filtration unit provides the sample-preparation stage.
Key Features
- Built-in diaphragm pumping enables direct liquid discharge without an external suction bottle.
- Independent filtration heads support parallel work and separate start/stop control.
- Detachable filtration components and a stainless-steel housing support cleaning, disinfection and maintenance.
- Mechanical knobs provide direct control of filtration units.
Applications
Use for microbial limit sample preparation in pharmaceutical and medical-device process water, suitable nonsterile pharmaceutical preparations, bottled water, beverages, liquid raw materials and other compatible water samples. Select the membrane, culture medium and incubation conditions for the sample and the organisms being assessed.
