All-Glass Filtration Assembly

All-glass filter holder design restricts contact with reactive surfaces such as steel or rubber to minimize contamination of sample or filtrate.

All-Glass Filter Holder Product Benefits:

• Standard 25 or 47mm filtration funnels mount on filtration flask using a ground glass joint
• Support base outlet drip tube is positioned below the side arm connection to prevent sample aspiration into the vacuum line
• All wetted surfaces are borosilicate glass with the exception of stainless steel and PTFE support options
