These vacuum microfiltration assemblies are designed to handle up to 500 mL of sample liquids for the analysis of particulate or microbiological contamination. The funnel is graduated from 100 to 250 mL in 25 mL increments. PreFilter Size is 35 mm and the approximate filter area is 9.6 cm2. Connection to our 1 liter filtration flask (available as an accessory) is made with a #8 silicone stopper.
The 90 mm vacuum microfiltration assemblies are designed for large sample volumes or samples with high particulate loads that would tend to clog a 47 mm diameter filter. Filtration rates are up to four times faster than 47 mm filters. The funnel is graduated from 300 to 1000 mL in 50 mL increments. Maximum funnel capacity is 1100 mL. PreFilter Size (mm) is 70 mm diameter and the approximate filter area is 38.5 cm2. Connection to our 1 liter filtration flask (available as an accessory) is made with a #8 silicone stopper.
The 25 mm vacuum microfiltration assemblies are designed to handle small volumes of liquids for analysis of particulate or microbiological contamination. The funnel is graduated from 5 to 15 mL in 1 mL increments. PreFilter Size is 16 mm diameter and the approximate filter area is 2.5 cm2. Connection to our 125 mL filtration flask (available as an accessory) is made with a No. 5 silicone stopper.
