Description
1. Product Overview
PTFE syringe filter is a high-performance, chemically inert membrane filtration device engineered for critical sample preparation in laboratory and industrial workflows. Its primary industrial use is the clarification and sterilization of aggressive solvents, acids, bases, and HPLC/GC samples prior to analytical instrumentation. The key value proposition lies in its superior chemical resistance, low extractables, and consistent pore integrity, which ensure contaminant-free results and protect sensitive equipment. In a market where analytical accuracy and operational uptime drive profitability, PTFE syringe filters are strategically important for reducing rework, extending column life, and meeting stringent QC standards globally.
2. Key Specifications & Technical Characteristics
- Material Components: Hydrophobic PTFE membrane with polypropylene housing; options for glass fiber pre-filter layer for high particulate loads
- Pore Size & Grade: Available in 0.22 μm and 0.45 μm, USP Class VI compliant, HPLC certified for low UV-absorbing extractables
- Physical Characteristics: Diameter options 13 mm, 25 mm, 33 mm; Filtration area 1.7 cm² to 4.9 cm²; Color-coded housing for pore size identification; Max operating pressure 87 psi / 6 bar
- Chemical Compatibility: pH 1–14; Compatible with all organic solvents, strong acids, and bases; Temperature resistant up to 130°C
- Packaging Options: Individually sterile blister packs; Non-sterile bulk packs of 100/500/1000 pcs; Cleanroom double-bagged for semiconductor/pharma use
- Shelf Life: 5 years from date of manufacture when stored in original sealed packaging at 10–30°C, 40–60% RH
3. Core Industrial Applications
- Primary Industries: Pharmaceuticals, biotechnology, chemicals, environmental testing, food & beverage, semiconductor, and petrochemicals
- Specific Operational Use Cases: Mobile phase filtration for HPLC/UPLC, dissolution sample prep, protein precipitation filtrations, aggressive solvent cleaning, air/gas venting, sterilizing corrosive liquids
- Performance vs Alternatives: Outperforms Nylon and PVDF filters in solvent compatibility and low protein binding. Unlike cellulose acetate, PTFE will not degrade in DMSO, THF, or concentrated acids, eliminating membrane breakdown and sample contamination
- Efficiency & Cost Advantages: Low hold-up volume design reduces sample loss to <10 μL. High dirt-loading capacity decreases filter change frequency by up to 40%, lowering consumable spend and analyst downtime
4. Competitive Advantages
- Quality Consistency: ISO 9001 & ISO 13485 certified manufacturing with 100% integrity testing and batch-level HPLC extractables reporting
- Supply Reliability: Dedicated production lines with 98.7% on-time delivery rate; 3 global distribution hubs in US, EU, and APAC for 72-hour dispatch
- Logistics Capability: IATA-certified for air freight; UN3480-compliant sterile packaging; Full customs documentation including CoA, CoC, RoHS, REACH
- Price Competitiveness: Tiered volume pricing with 15–28% savings at container-level orders; FOB/CIF/DDP terms available
- Sustainability: Recyclable PP housing; REACH & RoHS compliant; Reduced solvent waste due to high loading capacity
- Technical Support: Full regulatory documentation pack, method development support, free validation samples, and 24/7 application engineer access
5. Commercial & Supply Information
