Product Features
1. Be careful to prevent the filter membrane clip from accidentally falling off or being damaged during use to avoid injury.
2. Avoid exposing the filter membrane clip to fire or high-temperature objects to prevent fire hazards or the release of harmful substances.
3. When collecting liquid samples, it is recommended to use a filter membrane with a larger pore size to prevent deformation of the clip and leakage.
Frequently Asked Questions (FAQ)
What are the primary applications of a PTFE filter holder?
PTFE filter holders are primarily used for filtering highly corrosive gases, strong acids, and alkaline solvents. They are also widely utilized in aerosol sampling, low-concentration particle sampling, and environmental monitoring operations.
What sizes of PTFE filter holders do you offer?
We offer a wide range of standard sizes to fit different filtration requirements, including 13mm, 25mm, 37mm, 40mm, 47mm, 50mm, and 90mm diameters.
Why is PTFE chosen for chemical filtration?
PTFE (Polytetrafluoroethylene) is chosen for its extreme chemical inertness, wide temperature stability, low friction coefficient, and low-adhesion surface, which prevents residue buildup and ensures sample purity.
Are the PTFE reagent bottles suitable for high-purity chemical storage?
Yes, our PTFE reagent bottles have excellent chemical resistance and low trace metal background, making them ideal for storing high-purity acids, organic solvents, and hazardous chemicals.
How do I prevent leakage when using the filter holder for liquid sampling?
To prevent pressure buildup and possible leakage or deformation of the membrane clip, we recommend selecting a filter membrane with an appropriate and larger pore size, especially when filtering viscous or high-particle liquids.
