Provide accurate integrated sampling without a sampling pump.
Siltek-treated components ensure accurate sampling of active components.
Excellent for sampling times from 0.5 hour to 125 hours.
Air sampling canisters sold separately.
Description
Restek’s passive air sampling kit incorporates all the hardware necessary to collect air samples and is easy to assemble for field sampling.* The improved filter design greatly reduces the number of potential leak sites.
The passive air sampling kit is available in seven sampling flow ranges and in stainless-steel or Siltek-treated finish. The stainless-steel kit is ideal to partner with the Restek TO-Can air sampling canister for TO-14A and TO-15 methods. Use the Siltek-treated version with the Restek SilcoCan air sampling canister when collecting low-level volatile sulfur compounds or other active compounds.

Veriflo SC423XL flow controller
This flow controller is the heart of the sampling train. It is a high-quality device designed to maintain a constant mass flow as the pressure changes from –30" Hg to 7" Hg. (We recommend you stop sampling at or before 7" Hg of vacuum.) All wetted parts of the flow controller can be Siltek treated.
Stainless-steel vacuum gauge, 1/8" NPT
Fitted to the flow controller, the gauge monitors canister vacuum change during sampling.
1/4" Siltek sample inlet
The 0.3 m x 1/4" tubing includes a stainless-steel nut on the inlet end to prevent water droplets from accumulating at the edge of the tubing where they could be pulled into the sampling train.
2 µm frit filter and washer
Located prior to the critical orifice to prevent airborne particles from clogging the critical orifice. Replaceable. Available in stainless steel or Siltek treated for optimum inertness.
Interchangeable critical orifice
An interchangeable ruby critical orifice allows you to control the flow with very high precision.
Note: All fitting connections are 1/4" tube, except where noted.
*Vacuum/pressure gauge included in kit; air sampling canisters sold separately.
