High-Performance Material
- High-Purity Molded PFA: All wetted components are constructed from molded PFA (perfluoroalkoxy), providing unmatched chemical inertness and ensuring zero metal contamination during critical sample preparation.
- Extreme Thermal Stability: Engineered to perform reliably across a broad temperature range, from -200°C to +260°C (-328°F to +500°F).
- Non-Stick Surface: The smooth PFA finish prevents sample carryover and allows for easy cleaning, making it ideal for ultra-trace analytical work.
Functional Design
- Efficient Membrane Replacement: Designed so that filter membranes can be replaced without the need to disconnect fluid lines, saving time and maintaining system purity.
- Tool-Free Hand Tightening: Precision threads allow the assembly to be secured by hand, eliminating the need for wrenches and reducing the risk of over-tightening or damaging components.
- Secure 1/4" Connections: Features ferrule nut connections specifically designed for 1/4" (6.35 mm) tubing on both the inlet and outlet for a reliable, leak-proof seal.
Ideal Applications
- Semiconductor & Geochemistry: The preferred choice for laboratories requiring ultra-pure fluid handling and filtration for high-sensitivity trace metal analysis.
- Corrosive Chemical Handling: Ideal for filtering aggressive acids, bases, and organic solvents that would degrade traditional glass or standard plastic assemblies.
- Cleanroom Environments: Optimized for high-throughput clean labs where contamination control and rapid maintenance are critical to laboratory productivity.
