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 ²
• 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
