Filter Holders and PTFE Membranes
Filtration Systems for Analysis of Air, Gases and Liquids
The filter holders are made of inert, high purity, acid and temperature resistant PFA polymer. Thus, they are particularly suitable for applications under ultra-pure conditions, such as in environmental analysis. For applications with high pressures, clamps made of glass-fiber reinforced Tefzel™ are also available. There are already a large number of preconfigured (standard) filter units available. However, you also have the option of configuring your specific filter unit. We will be happy to advise you on the selection of components.
Filter Holders for Laboratory Analysis
As a standard, preconfigured filter units are available with the following diameters and filter stages:
- 13 mm (Luer connection, single stage)
- 25 mm (single stage)
- 47 mm (single, two, three and four stages)
- 50 mm (single stage)
Other sizes and designs on request.
PTFE Membranes for Filter Holders
The membranes are made of pure and inert PTFE polymer, which is resistant to most concentrated acids and bases. They are available to match the diameter of the relevant filter holder (13 / 25 / 47 / 50 mm) and with different pore sizes (0.1 / 0.2 / 0.45 / 1.2 / 5 µm).
