The All-Glass Filtration Assembly is designed to restrict contact with reactive surfaces such as stainless steel or rubber to minimize contamination of sample or filtrate. Standard 25 and 47 mm filtration funnels mount on filter flask using a ground glass joint. The outlet of the support base drip tube is positioned below the side arm connection to prevent sample aspiration into the vacuum line.
Vacuum filter aqueous, organic, or corrosive liquids such as HPLC solvents. All wetted surfaces are borosilicate glass with the exception of the stainless steel and PTFE support options.
Units are offered with a borosilicate glass funnel, sintered glass base, stainless steel screen, or PTFE support and base, anodized aluminum clamp, and receiver flask.
