Tisch
Polyethersulfone Syringe Filters, 25mm, 0.22 um, w/ GD-4 Pre-Filter, Nonsterile, 100/Pk SKU: GD17167

Polyethersulfone (PES) Syringe Filters - GD17167

Featuring advanced polyethersulfone membrane technology combined with GD-4 glass fiber prefiltration for reliable bacterial removal and sterilization applications. Nonsterile 0.22µm absolute pore rating provides complete microbial retention while maintaining high flow rates through challenging sample matrices. Tisch Scientific integrates hydrophilic PES membranes with robust dual-layer construction, enabling autoclave sterilization at 121°C when sterility assurance is required.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane delivers instant wetting without surfactants or pre-treatment
• Exceptional chemical resistance tolerates aggressive solvents and pH extremes from 1-14
• Low protein binding preserves sample concentration and maintains biological activity
• 0.22µm absolute pore size ensures complete bacterial and microorganism removal
• Autoclavable construction allows sterilization at 121°C for 30 minutes or gamma irradiation

Key Construction Characteristics

• GD-4 glass fiber prefilter removes larger particulates, protecting the downstream membrane
• Dual Luer-Lok/Luer Slip design ensures universal compatibility with all syringe types
• Reinforced housing withstands 87psi burst pressure for secure high-pressure filtration
• 100µl holdup volume minimizes sample loss when processing precious or limited volumes

GD17167 syringe filters deliver consistent 32ml/min flow rates through an optimized 4.08cm² active membrane area, accelerating your sterile filtration workflows without compromising retention efficiency. Glass fiber prefiltration significantly extends membrane life to achieve 50ml throughput capacity, maximizing your cost-effectiveness while maintaining 43.51psi bubble point specifications. Autoclave compatibility at 121°C provides flexibility for your applications requiring certified sterility, transforming nonsterile units into validated sterile filters for critical pharmaceutical and biotechnology processes.
