Glass Fiber Filters
|
Glass Fiber Filters are the most
commonly used filters for particulate sampling. All of the glass fiber
filters we stock are binder free and exhibit at least 99.9% efficiency
for 0.3 micron dioctyl phthalate (DOP) smoke particles. We offer two
different brands: Whatman 934AH and a less expensive Japanese
equivalent from Advantec/MFS grade number GC-50. Maximum temperature is
500°C (900°F). Not recommended for metals analyses.

Quartz Fiber
Filters
|
Quartz Fiber Filters are
manufactured from pure quartz without binder and are frequently used
for sampling for metals analyses and acidic gases. Filters are
preheated to reduce organic contaminates.

PTFE Coated Glass Fiber Filters |
|
PTFE Coated Glass Fiber Filters are constructed from borosilicate
microfibers and bonded with PTFE. The filters can be folded and handled
without loss of fibers. Great for especially low loading rates.
Specifically recommended for Method 26 and PM10
sampling.

Teflon® Filter
Membranes
|
Teflon® Filter Membranes are produced of pure PTFE resins. They
withstand the most severely corrosive conditions at temperatures as
high as 260°C (500°F) and down to the cryogenic range.
The membrane is hydrophobic and maintains its strength wet or dry.
