SimPure Syringe Filter PTFE 200 PCS 25mm 0.22um - Hydrophobic Lab

In this review the SimPure Syringe Filter PTFE 200 PCS is evaluated for lab users who need a bulk supply of reliable hydrophobic filters for solvent and gas work. The bottom line: these 25mm, 0.22um PTFE needle filters are best for routine sample cleanup and solvent filtration because of their broad chemical compatibility and consistent pore size, which together deliver predictable particle retention and low sample interaction.

Key Features

• Hydrophobic PTFE membrane: Naturally hydrophobic material provides excellent chemical compatibility and helps repel aqueous contamination during solvent and gas filtration.
• Uniform pore size: 0.22um pores on a 25mm disc deliver consistent particle retention and high porosity for repeatable filtration performance.
• High throughput pack: 200 pcs barreled packed gives a sizable supply for labs that filter many samples without frequent reordering.
• ISO 9001 quality control: Quality management inspections throughout production increase confidence in batch consistency and filter integrity.
• Durable housing: Polypropylene housing with a Luer lock threaded interface minimizes leaks and sample contamination during use.
• Autoclavable option: The filters can be autoclaved at 121C for 30 minutes for users who need to sterilize hardware between uses, although filters are supplied non-sterile.

Who It's For

These PTFE syringe filters are aimed at chemists, technicians, and labs that frequently filter organic solvents, acids, alkalis, or gases and need a hydrophobic membrane that resists chemical attack. The 200-piece quantity suits high-throughput environments, teaching labs, or groups that process many samples where cost per filter matters.

Users who require pre-sterilized filters for critical cell or microbiology work should look elsewhere or plan to autoclave before use, since these are supplied non-sterile. Also, very small-volume analytical work that needs specialty filter housings may prefer different formats.

Pros & Cons

Pros

• Broad chemical compatibility of the PTFE membrane makes these filters suitable for most organic solvents and aggressive solutions.
• Consistent 0.22um pore size and 25mm disc deliver reliable particle removal in routine filtration tasks.
• Good value and quantity: the 200-piece pack reduces downtime and purchasing frequency for busy labs.

Cons

• Supplied non-sterile, so additional sterilization is needed for sterile applications despite being autoclavable.
• Bulk barreled packaging may not suit labs that prefer individually wrapped sterile filters.

Specifications

Our Verdict

The SimPure PTFE 25mm 0.22um syringe filters are a sensible choice for labs that need a robust, chemically resistant filter in large quantities. Their uniform pore size and ISO 9001 quality control make them reliable for solvent and gas filtration, while the 200-pack offers strong value; users who need ready-sterile filters should note the non-sterile supply.

Frequently Asked Questions

Are these filters suitable for organic solvents?
Yes, the hydrophobic PTFE membrane has broad chemical compatibility and is suitable for most organic solvents.

Do the filters come sterile?
No, they are supplied non-sterile but the housing and membrane can be autoclaved at 121C for 30 minutes if sterilization is required.

What connection type do they use?
The filters have a Luer lock threaded interface on a polypropylene housing to reduce leaks and contamination.
