311110 Model KG13C Vacuum Holder Assembly Funnel - 13mm Diameter for Industrial Vacuum Systems & Laboratory Applications

Borosilicate glass filter holder assembly for microanalysis of small volumes of liquids under vacuum. Filter biological samples or organic solvents. The holder utilizes a 25mm filter membrane yet concentrates the sample into a 13mm diameter 1.2cm2 area. The anodized aluminum clamp secures the membrane between the funnel and sintered glass frit support base. Available in three graduated funnel capacities 100, 500, or 1000 mL. The 13mL/100mL features a two-part ground glass funnel for concentrating samples. The 13mL micro funnel mounts directly over the membrane. The No.5 silicone stopper mounts in a standard 125mL filter flask.
