1. Veriflo™SC423XL flow controller
This flow controller is the heart of
the sampling train. It is a high-quali-
ty device designed tomaintain a
constantmass flow as the pressure
changes from 30" Hg to 5" Hg (we
recommend you stop sampling at or
before 5" Hg of vacuum). All wetted
parts of the flow controller can be
Siltek
®
treated.
2. Stainless steel vacuum gauge
Fitted to the flow controller, the
gaugemonitors canister vacuum
change during sampling.

The 0.3m x

-inch tubing includes a
stainless steel nut on the inlet end,
to prevent water droplets from
accumulating at the edge of the tub-
ing, where they could be pulled into
the sampling train.
4. 2-micron frit filter andwasher
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.
5. Interchangeable critical orifice
An interchangeable ruby critical orifice allows you to control the flowwith very high precision.
To select the correct critical orifice for your sample, see table below. Available in stainless steel,
or Siltek
®
treated for optimum inertness.

Accuracy&Efficiency
Our heating jackets can help you prepare your canisters
for sampling faster andmore efficiently.The jacket’s
novel design ensures complete cleaning by heating the
canister and valve together and prevents condensation,
ensuringmore accurate results.Two temperature set-
tings, 75ºC and 150ºC. Fits all canisters up to 6L in size.
Our passive sampling kits include all hardware required for field sampling (except the can-
ister) and assemble easily. Our kit was designed to reduce the number of potential leak
sites and is available in seven flow ranges, and in stainless steel orwith Siltek
®
surface
treatment. Individual parts are also available.
