Inherently Low Ash Membrane Ideally Suited
for Multiple NIOSH Analytical Methods
- Assures gravimetric stability with low moisture pick-up and low tare weight.
- Low ash.Provides interference-free silica determinations.
- 5 μm pore size meets NIOSH and OSHA requirements.
- 25 and 37 mm sizes are ideal for use in 颇尔 Air Monitoring Cassettes.
- Excellent membrane choice for sampling airborne metals, silica, and dust.
