High-Performance Material
- High-Purity Molded PFA: All wetted components are constructed from high-purity PFA (perfluoroalkoxy), ensuring chemical inertness and preventing trace metal contamination in ultra-clean environments.
- Tefzel™ (ETFE) Clamp Nut: Specifically equipped with a Tefzel™ clamp nut for enhanced mechanical strength, making it ideal for high-pressure laboratory filtration applications.
- Broad Thermal Stability: The PFA wetted components withstand a massive temperature range from -200°C to +260°C (-328°F to +500°F), while the Tefzel™ clamp remains stable up to 148°C (300°F).
Functional Design
- Simplified Maintenance: The assembly is designed to allow for filter membrane replacement without the need to disconnect fluid lines, ensuring system integrity and reducing downtime.
- Secure 1/4" Connections: Features precision ferrule nut connections specifically for 1/4" (6.35 mm) tubing on both the inlet and outlet for a reliable, vacuum-tight seal.
- Wrench Assembly: To ensure a leak-proof seal and maintain the torque required for high-pressure use, the use of a wrench set is recommended for final assembly.
Ideal Applications
- High-Pressure Filtration: The Tefzel™ clamp provides the necessary reinforcement for pressurized fluid systems in semiconductor and chemical processing.
- Trace Metal & Geochemistry: An essential tool for ultra-trace analysis where 47 mm membranes are used to filter aggressive acids and high-purity reagents.
- Industrial Fluid Handling: Perfectly suited for environments requiring both chemical resistance and high mechanical durability in sample preparation and cleanroom workflows.
