Filter Media
| Apex Instruments offers a wide
range of filter media to meet your sampling requirements.
Listed below are the standard media and sizes that we normally
stock. Additional materials and sizes are available upon request. |

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 Grade E equivalent from Tremont. Maximum temperature is 500°C (900°F).
Not recommended for metals analyses. |

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. |
