SimPure Syringe Filter PTFE 25mm 0.22um Hydrophobic Membrane - Lab

In this review of the SimPure Syringe Filter PTFE 500 PCS pack, the bottom line is simple: these are high-throughput, hydrophobic needle filters built for labs that need reliable solvent and gas filtration without fuss. The reviewer found the filters useful for routine HPLC/GC sample prep and organic solvent work because the hydrophobic PTFE membrane tolerates aggressive solvents and resists wetting, while the 25mm, 0.22um discs deliver consistent particle retention across hundreds of uses.

Key Features

• Hydrophobic PTFE membrane: Offers broad chemical compatibility and strong chemical stability for filtering organic solvents and corrosive solutions without membrane breakdown.
• Uniform 0.22um pore size: Provides high retention efficiency and consistent filtration performance for HPLC and GC sample cleanup.
• 25mm disc diameter, 500 pcs: Large pack size supports high-throughput workflows and reduces the need for frequent reordering.
• Luer lock polypropylene housing: Threaded interface ensures secure syringe connection and avoids sample contamination from adhesives.
• ISO 9001 quality control: Multiple inspection steps aim to ensure consistent production quality across the entire batch.
• Autoclavable construction: Housing can be autoclaved at 121C for 30 minutes if sterilization is required before use.

Who It's For

These syringe filters suit analytical labs, chemical synthesis groups, and technicians who routinely filter organic solvents, acids, bases, and gases prior to HPLC or GC analysis. The pack of 500 is aimed at teams that need a large supply for daily sample prep or method development.

They are less appropriate for sterile cell culture work as the product is sold non-sterile; users requiring pre-sterilized, individually packaged filters should look for sterile options or perform validated sterilization procedures before use.

Pros & Cons

Pros

• Hydrophobic PTFE membrane gives wide chemical compatibility for solvents, acids, and alkalis.
• Consistent 0.22um pore size and 25mm diameter ensure reliable retention for HPLC and GC sample cleanup.
• Large 500-piece pack supports high-throughput labs and reduces ordering frequency.
• Autoclavable polypropylene housing with Luer lock minimizes connection issues and contamination risk.

Cons

• Sold non-sterile, so additional sterilization is required for aseptic applications.
• Bulk packaging may be excessive for users with only occasional filtration needs.
