Sterlitech All-Glass Filtration Assemblies

• All-glass design restricts contact with reactive surfaces such as steel or rubber to minimize contamination of sample or filtrate.
• Standard 25 or 47mm filtration funnels mount on filtration flask using a ground glass joint.
• Outlet of support base drip tube is positioned below the side arm connection to prevent sample aspiration into vacuum line.
• All wetted surfaces are borosilicate glass with the exception of stainless steel and PTFE support options.
