Product Description
Speed up large-volume membrane filtration with a 90 mm setup that moves liquid up to four times faster than a standard 47 mm unit. The replaceable fritted disc means a clogged or contaminated support never forces you to retire the whole apparatus.
This listing is for Kimble catalog number 953770-0090: ULTRA-WARE 90mm Microfiltration Assembly. The kit includes a 1000 mL graduated funnel, a 90 mm glass support base, a 40-60 micron fritted glass disc, an anodized aluminum clamp and a #8 silicone stopper. The funnel reads from 300 to 1000 mL in 50 mL steps and holds up to 1100 mL. It seats on a 1 liter filter flask, sold separately, through the stopper. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
Key Features
- Faster throughput – The 90 mm format filters up to four times faster than 47 mm filters.
