The microbiology pump is ideal for the microbiological analysis of aqueous samples using membrane filter technology. It pulls the sample through the filter and liquid channel and eliminates the need for a vacuum source. It also ensures that the liquid flows in one direction without backing up and contaminating the analysis. The pump is easy to clean and features a small footprint and one-way liquid channel to maximise the working area and minimise the risk of contamination. The fluid channel is easy to install and replaceable to avoid potential biofilm formation. Filtration can be easily controlled via the soft-touch keypad with on/off and pulse function. Fixed settings prevent changes to the filtration parameters. Meets the filtration parameters of membrane filter technology described in EPA, ISO, and ASTM standards.
