Stainless Steel Filter Holders FAQ

The SF Filter Holder is made from 316 stainless steel (SS316) and can be sterilized by either steam sterilization (autoclaving) or flame sterilization. Autoclave (Steam Sterilization): 1 Disassemble the lid kit, funnel, and support base before autoclaving. 2. terilize at 121–123°C (250–253°F), 1.0 bar (15 psi) for 15–20 minutes. Flame Sterilization: Follow the instructions provided in the Flame Sterilization – Graphical Instruction guide for safe and proper flame sterilization.

Yes. Flame sterilization has been validated by SGS Taiwan Ltd. and shown to be as effective as steam sterilization (autoclaving) for eliminating common microorganisms, including Escherichia coli (E. coli) and Pseudomonas aeruginosa, across a range of bacterial concentrations.

The SS316 stainless steel membrane support can become clogged over time due to salt crystallization or carbonized residues. To maintain optimal filtration performance and flow rate, perform periodic ultrasonic cleaning in addition to routine cleaning and maintenance. Regular cleaning helps prevent blockages and extends the service life of your SF Filter Holder.

The SS316 stainless steel membrane support may gradually become clogged or lose filtration efficiency due to salt crystallization, carbonized residues, or repeated flame sterilization. Although periodic cleaning can help restore performance, the membrane support is a wear component and may need to be replaced over time to maintain optimal flow rate and filtration efficiency.
