PES Syringe Filters w/ GD-4 Pre-Filter, 0.22 um, 25mm, Sterile, 100/Pk SKU: GD17039

Polyethersulfone (PES) Syringe Filters - GD17039

Featuring advanced polyethersulfone membrane technology with integrated GD-4 glass fiber prefiltration for sterile bacterial removal applications. Certified 0.22µm pore size ensures complete retention of bacteria and microorganisms while maintaining exceptional flow rates through challenging sample matrices. Tisch Scientific combines hydrophilic PES membranes with robust housing design to deliver reliable sterilization performance across pharmaceutical, biotechnology, and clinical laboratory environments.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane provides instant wetting without surfactants or pre-treatment
• Superior chemical resistance withstands aggressive solvents and pH ranges from 1-14
• Low protein binding characteristics preserve sample concentration and biological activity
• 0.22µm absolute pore rating guarantees complete bacterial removal for sterile filtration
• Broad temperature stability maintains membrane integrity up to 60°C operating conditions

Key Construction Characteristics

• GD-4 glass fiber prefilter extends membrane life by removing larger particulates upstream
• Dual Luer-Lok/Luer Slip connections ensure universal compatibility with standard syringes
• Robust polypropylene housing withstands 87psi burst pressure for secure high-pressure operations
• 100µl holdup volume minimizes sample loss when processing precious or limited volume samples

GD17039 syringe filters deliver consistent 32ml/min flow rates through an optimized 4.08cm² filtration area, enabling rapid processing of your critical samples while maintaining sterility. Glass fiber prefiltration technology significantly extends membrane service life to achieve 50ml throughput volumes, maximizing your laboratory efficiency and reducing filter consumption. Individually packaged sterile units maintain certified 43.51psi bubble point integrity, ensuring reliable 0.22µm bacterial retention for your most demanding sterilization applications.
