Description

Ground glass connection points Funnel, Base, and Flask Sintered glass, Stainless steel, or PTFE filter support Borosilicate glass filter holder assemblies for the microanalysis of liquids for biological or particulate contamination under vacuum. The All-Glass design restricts contact with reactive surfaces such as steel or rubber to minimize contamination of filtrate. The 300mL graduated funnel mounts on the 1L flask by way of a 40/35 ground glass joint. The outlet tube of the support base is positioned below the the side arm connection of the the flask to prevent aspiration of the sample into the vacuum line. The anodized aluminum clamp secures the 47mm membrane between the funnel and base. While the sintered glass frit support base can be used for general filtration, the 304 stainless steel screen(w/ PTFE gasket) is recommended for viscous or proteinaceous solutions to maximize flow rate and the screen ensures particles will not be shed into the filtrate. The PTFE support can filter acidic solutions at a higher flow rate.  Unit includes: Funnel, Base/Support(gasket w/ screen), Clamp, Flask Please Note: ALL Advantec items have a maximum 48 hour cancellation window.
