PTFE Syringe Filters w/ GD-4 Pre-Filter, 0.45um, 25mm, Nonsterile, 100/Pk SKU: GD17036

Polytetrafluoroethylene (PTFE) Syringe Filters - GD17036

Featuring hydrophobic PTFE membrane technology with integrated GD-4 glass fiber prefiltration for superior chemical resistance in aggressive solvent applications. A 0.45µm pore configuration delivers reliable clarification while maintaining complete chemical inertness across organic solvents, acids, and bases. Tisch Scientific engineers combine ultra-resistant PTFE membranes with polypropylene housing to provide unmatched compatibility for pharmaceutical, analytical, and industrial filtration challenges.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane requires alcohol pre-wetting for aqueous solution filtration
• Universal chemical resistance handles all organic solvents, concentrated acids, and strong bases
• Exceptional thermal stability maintains performance at 60°C continuous operation
• 0.45µm pore size provides efficient clarification and coarse particulate removal
• Autoclavable construction allows sterilization at 121°C for validated protocols

Key Construction Characteristics

• GD-4 glass fiber prefilter captures larger particulates, extending primary membrane life
• Dual Luer-Lok/Luer Slip design ensures universal compatibility with standard syringes
• Polypropylene housing withstands 87psi burst pressure for secure high-pressure filtration
• 100µl holdup volume minimizes loss of precious reagents and limited sample volumes

GD17036 syringe filters achieve exceptional 35ml/min flow rates through a 4.08cm² active filtration area, accelerating your sample processing even with viscous organic solvents. Glass fiber prefiltration technology significantly extends membrane service life to deliver 100ml throughput capacity, maximizing your cost-effectiveness when filtering challenging matrices. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, providing flexibility for your applications requiring both chemical resistance and certified sterility assurance.

Wetability

Hydrophobic

• Aggressive solvents - Filtration of THF, DMF, DMSO, chloroform, acetonitrile without degradation
• HPLC sample prep - Clarification of samples in organic solvents, protecting column performance
• Strong acid filtration - Safe handling of concentrated HCl, H2SO4, HNO3, maintaining membrane integrity
• Protein precipitation - Clarification after organic solvent or acid precipitation protocols
• Air and gas venting - Hydrophobic properties allow gas passage while blocking liquid intrusion
• Pharmaceutical testing - Sample preparation for dissolution testing in aggressive media conditions
