FILTRATION
BOLA Vacuum Filters
Material: Temperature resistance: Chemical resistance:
PTFE, PFA from -200°C to +250°C +++ universal
Product description:
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 (page 332). 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.
Flow rate:
Flow capacity for water under vacuum of 100 kPa (1000 mbar) using a PTFE filtering membrane with a thickness of 0,2 mm:
