BOLA Filters

ptfe filter BOLA Suction Filters, PTFE
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.




ptfe frit BOLA Frits for Suction Filters, PTFE
Replacement frits made of porous PTFE, suitable for suction filters (Cat. No. F 765-..)

 



ptfe filter BOLA Pressure Pre-Filters, PTFE
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.

 

 

ptfe vacuum filter BOLA Vacuum Filters, PTFE 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. PFA collecting vessel, The filters are produced without plasticisers and have an almost universal chemical resistance. They do not release any trace elements into the filtrate.

 

 

ptfe vacuum filter funnel BOLA Vacuum Filter Funnels, PTFE, PFA Filtration unit made of PTFE with cone size 29 for connection to a vessel (must be suitable for vacuum) with socket size 29. Multi-stage hose connector with integrated lock screw for vacuum tubing with I.D. 6 and 8 mm, filtration surface 13,8 cm2 , easily exchangeable filtering membrane dia. 47 mm. Filling vessel made of PFA with PTFE lid for protection against contaminations.

 

 

ptfe filetr syringe BOLA Filter Adapters for Syringes, PTFE
Adaptors can be screwed together into multi-stage filters (prefilter, main filter). The low weight of only 14 g or 44 g allows easy exchange of the optionally available filtering membranes.

 

 

ptfe flow filter BOLA Flow Filters, PTFE Suitable for overpressure or vacuum, usable for example as added filter or as large-area in-line apparatus . Suitable for temperatures up to +160°C. The optionally available filtering membranes can be exchanged easily. Tubing can be connected to GL threads by means of the included laboratory screw joints. 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.

 

 

pfa flow filter BOLA Single-Stage Flow Filter, PFA
Filter made of PFA with connecting nut made of glass-fibre reinforced ETFE. Suitable for vacuum and overpressure up to max. 150 kPa (1.500 mbar) and for temperatures up to max. +160°C. Easy exchange of the optionally available filtering membrane. Couplings for connecting tubing with O.D. 6,35 mm (1/4”) are included.

 

 

pfa 3 stage filter BOLA Three Stage Flow Filter, PFA
Filter made of PFA with connecting nut made of glass-fibre reinforced ETFE. Suitable for vacuum and overpressure up to max. 150 kPa (1.500 mbar) and for temperatures up to max. +160°C. Multi-stage filtrations with up to 3 different filtering membranes are possible. Easy exchange of the optionally available filtering membrane. Couplings for connecting tubing with O.D. 6,35 mm (1/4”) are included.
