Thumbnail Filmstrip of PTFE Syringe Filters w/ GD-4 Pre-Filter, 0.22 um, 25mm, Nonsterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - GD17035
Featuring hydrophobic PTFE membrane technology with integrated GD-4 glass fiber prefiltration for aggressive solvent and gas filtration applications. A 0.22µm pore configuration ensures sterile-grade particulate removal while chemical inertness handles the most challenging organic solvents and corrosive reagents. Tisch Scientific combines ultra-resistant PTFE membranes with polypropylene housing construction to deliver unmatched chemical compatibility across pharmaceutical, analytical, and industrial applications.
Key Polytetrafluoroethylene (PTFE) Membrane Characteristics
- Hydrophobic membrane requires pre-wetting with alcohol for aqueous solutions
- Universal chemical resistance withstands all organic solvents, acids, and bases
- Exceptional thermal stability maintains integrity at 60°C continuous operation
- 0.22µm absolute pore rating provides complete bacterial and microorganism removal
- Autoclavable construction enables sterilization at 121°C for 30 minutes when required
Key Construction Characteristics
- GD-4 glass fiber prefilter extends membrane life by capturing larger particulates upstream
- Dual Luer-Lok/Luer Slip connectivity accommodates all standard syringe configurations
- Polypropylene housing withstands 87psi burst pressure for secure high-pressure operations
- 100µl holdup volume minimizes sample loss when filtering valuable or limited reagents
GD17035 syringe filters maintain 18ml/min flow rates through a 4.08cm² active membrane area, providing controlled filtration for your most aggressive chemical applications. Glass fiber prefiltration significantly extends membrane service life to achieve 100ml throughput capacity, maximizing your laboratory efficiency when processing challenging solvents. Autoclave compatibility at 121°C allows sterilization for critical applications, while the hydrophobic PTFE membrane ensures complete chemical resistance throughout your filtration protocols, requiring maximum inertness.
