Stainless steel 142mm membrane disk filter holder for laboratory application. Stainless steel disk filter holder for 142mm filter membrane, made of 316 stainless steel
CLEANING AND MAINTENANCE
• Disassemble the entire unit:
• Inspect screens for nicks or rough edges and check O-rings and gaskets for cracking and loss of
elasticity.
• Carefully remove O-rings with blunt-tipped forceps.
• Rotate (flip over) PTFE gasket (this minimizes flattening on the side in contact with the membrane).
• Clean all components with a standard, non-abrasive laboratory detergent:
• Threaded connections may be cleaned with a stiff-bristled brush.
v Sanitary connections, PTFE support screens, and interior surfaces may be cleaned with a sponge or
non-abrasive cloth.
• Rinse with hot tap water followed by a final rinse with distilled or deionized water.
• To sterilize:
• Assemble a completely dry filter with membrane. Attach hoses and clamps to holders. Tubing/hoses
should be less than or equal to 3 feet long (1 meter) and must be completely dry. Sealing clamps
should only be finger tight during assembly.
• Wrap both inlet and outlet hoses with steam permeable paper.
• Autoclave the holder at 121 C (250 F) for the time listed in the table below. Slow exhaust only.
