PALL 66467 GLA-5000 PVC Membrane Disc Filters - 5 µm, 37 mm, with support pads (100/pkg)

These membrane disc filters are designed for airborne particulate sampling, making them ideal for environmental monitoring, workplace safety testing, and industrial hygiene applications such as dust and aerosol collection.

PVC membranes like GLA-5000 are low in ash content and absorb minimal moisture, which helps ensure stable pre- and post-weighing results. This makes them well-suited for accurate gravimetric measurements.

A 5 µm pore size is intended for capturing coarse particles such as dust, fibers, and larger aerosols while maintaining consistent airflow during sampling. It is commonly used in occupational air monitoring.

Support pads are used to reinforce the membrane during sampling, helping prevent tearing or deformation. They also promote even airflow distribution and improve overall filtration stability in cassette systems.

This model features a 37 mm diameter PVC membrane with 5 µm pore size, supplied with support pads in packs of 100. The size is compatible with standard air sampling cassettes used in environmental and industrial testing.
