Use our all-glass filtration systems for your work with particulate, microbiological, and HPLC to minimize contact between material and sample. 47 mm glass membrane funnel mounts on a flask reservoir with a ground glass joint. The glass membrane funnel’s drip tube is positioned below the ¼” barb to stop any sample aspiration in to the vacuum hose. Clean the all-glass system with organic and aqueous solvents.

Please Note: Vials, caps, and septa formerly under the Kinesis brand have now been rebranded Cole-Parmer. All the same great features and specifications, just with a new and improved look.
