• Improved filter design reduces the number of potential leak sites
• Stainless steel kit is ideal to partner with the TO-Can air sampling canister for TO-14A and TO-15 methods
• Siltek-treated version with SilcoCan air sampling canister is suitable when collecting low-level volatile sulfur compounds or other active compounds

Available in seven sampling flow ranges

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 to 7 in. Hg. All wetted parts of the flow controller can be Siltek treated.

Stainless steel vacuum gauge, 1/8 in. NPT
Fitted to the flow controller, the gauge monitors canister vacuum change during sampling.

0.25 in. Siltek sample inlet
The 0.3m x 0.25 in. 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-micron 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 0.25 in. tube, except where noted.
