Question/Answer

Hi - could you supply 0.8uM 37mm PVC membrane filter in a 3-piece cassette? If so, can you indicate the price. Thanks

We are not aware of any supplies of 0.8 micron PVC filter material. Our vendors discontinued that item about 10 years ago.

Expiration date for cassette

We do not specify an expiration date on most cassettes. We do recommend using the product within 18 months of the date of purchase along with storage at room temperature in a climate controlled room to ensure the best performance.

How are these used

For specific use instructions consult the sampling method of choice. Generally speaking a pump is attached to one side of the cartridge and a specific volume of air (generally measured by time of exposure and the capacity of the pump) is drawn across the filter. The cartridge is then capped and send to a lab for analysis.

can this be used to collect airborne silica in response to OSHA\'s new Silica Exposure standard?

The OSHA method for silica sampling says to use preweighed, 37 mm, 5 um, 3-piece, PVC cassette with a cyclone sampler. The cassette that you would need is CU37500PVCPW. We do not sell cyclone samplers.

I would like to know who makes the cassetts and filters, thanks in advance, Dra. Murillo

We manufacture this product at Environmental Express.

What are the significant figures for your preweights in ug amounts, please send me an example coa

The cassettes are weighed to 5 decimal places. They do not come with a COA.
