KIMBLE ULTRA-WARE 90mm Microfiltration Assembly

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. The assembly with replaceable fritted glass support is used for general filtration.

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 is 70 mm diameter and the approximate filter area is 38.5 cm �

Connection to our 1 liter filtration flask (available as an accessory) is made with a #8 silicone stopper

Unit is supplied with a 40-60 micron porosity fritted glass disc, a 90 mm glass support base, a 1000 mL graduated funnel, an anodized aluminum clamp and a #8 silicone stopper

The fritted glass support disc can be replaced if it becomes clogged or exchanged if sample-to-sample cross-contamination is a concern

Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
