DWK Life Sciences (Kimble) Ultra-Ware® Microfiltration Assembly with Replaceable Fritted Glass Support, 350 mm H

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 dia 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 cm2
• Connection to our 1 L filtration flask (available as an accessory) is made with a #8 silicone stopper
• Unit is supplied with a 40 to 60 µ 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
