Description
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. This assembly with stainless steel support is used for filtering viscous or proteinaceous solutions or to produce ultra-clean filtrate.
• 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
• Prefilter size is 70 mm diameter, and the approximate filter area is 38.5 cm2
• Connection to a 1 liter filtration flask (available as an accessory) is made with a #8 silicone stopper
• Maximum funnel capacity is 1100 mL
• This unit is supplied with a 304 stainless steel support screen, a glass support base, a 300 mL graduated funnel, an anodized aluminum clamp and a # 8 silicone stopper
• 80 x 80 304 stainless steel mesh, 0.0055 opening size, 19.4% open area, 0.007 wire diameter
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
