PES Syringe Filters w/ GD-4 Pre-Filter, 25mm, 0.45um, Sterile, 1000/Pk SKU: GD17040

Polyethersulfone (PES) Syringe Filters - GD17040

Featuring hydrophilic polyethersulfone membrane technology with integrated GD-4 glass fiber prefiltration for superior clarification performance. Sterile 0.45µm pore configuration delivers exceptional flow rates while efficiently removing particulates and suspended solids from diverse sample matrices. Tisch Scientific engineers combine robust PES membranes with dual-layer filtration architecture to maximize throughput and extend filter life in demanding laboratory applications.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane ensures immediate wetting without surfactants or pre-treatment steps
• Broad chemical compatibility withstands aggressive solvents and extreme pH conditions from 1-14
• Low protein binding properties preserve sample integrity and prevent analyte loss
• 0.45µm pore size provides reliable clarification and coarse particulate removal
• Heat-stable construction maintains performance characteristics up to 60°C operating temperature

Key Construction Characteristics

• GD-4 glass fiber prefilter captures larger particles, extending primary membrane service life
• Dual Luer-Lok/Luer Slip connectivity accommodates all standard syringe configurations
• Reinforced polypropylene housing withstands 87psi burst pressure for secure filtration
• 100µl holdup volume minimizes sample loss when processing valuable or limited samples

GD17040 syringe filters achieve industry-leading 65ml/min flow rates through an optimized 4.08cm² active filtration area, dramatically reducing your sample processing time. Glass fiber prefiltration technology protects the primary membrane from premature fouling, consistently delivering 50ml throughput volumes while maintaining 31.91psi bubble point integrity. Individually packaged sterile units ensure contamination-free performance for your critical applications requiring both clarification and sterility assurance.
