APPARATUS FOR FILTERING A REAGENT

摘要

The filtering apparatus is used in combination with at least one analytical instrument, especially a particle analyzer and substantially comprises a controlled pump unit having an inlet side and an outlet side. The inlet side of the controlled pump unit is connected to a reservoir for a liquid medium to be filtered. The outlet side is connected to a filtering unit. An intermediate storage unit for intermediately storing the filtered liquid medium is connected to the filtering unit. The filtered liquid medium is fed to the analytical instrument from the intermediate storage unit which contains level detectors for detecting the liquid level in the intermediate storage unit. The level detectors are connected to a control unit for controlling the controlled pump unit.
