Whirl-Pak® Pipette Filter Sleeve - Box of 500

Prevents solids from plugging the tip of the pipette when sampling liquids that may contain solid particles. Half of the sleeve is made with the 330 micron hole size filler material. The pipette slides into the sterile sleeve and is inserted into the liquid to be tested. The liquid will pass through the filter, but not the solids. The sleeve is sized to hold a 10 ml pipette. Each pack of 25 comes packaged in a sterile Whirl-Pak® bag, which can be closed after each use. Box of 20 packs (500 sleeves).
