BOLA Suction Filters, PTFE
Cat.-No. F 765-...
Consisting of a receiver made of PTFE with female thread UNF ¼” 28 G and an easily exchangeable frit made of porous PTFE (Cat. No. F 766-..). Ideal prefilters in front of pump systems for protecting gaskets, pistons or column packings against premature wearing due to contaminations.

BOLA Pressure Pre-Filters, PTFE
Cat.-No. F 780-...
For direct fine filtration in front of HPLC columns. For filtering membranes (available optionally) with a diameter of 13 mm and a thickness between 0,1 and 3 mm, filtration surface of 132 mm2 for filtration with nearly no dead volume. The membrane can be exchanged by hand. Connection threads on both sides UNF ¼” 28 G.

BOLA Vacuum Filters, PTFE
Cat.-No. N 1650-...
Filtration unit made of PTFE, multi-stage hose connector with integrated lock screw for connecting vacuum tubing with I.D. 6 mm or 8 mm, PTFE supporting disc to fit optionally available filtering discs. Collecting vessel made of PFA, filling vessel with lid for protection against contaminations also made of PFA. The filters are produced without plasticisers and have an almost universal chemical resistance. They do not release any trace elements into the filtrate. Due to the non-adhesive surface, they are easy to clean and can be reused.
