1. Veriflo™ SC423XL flow controller

This flow controller is a high-quality

device designed to maintain a con-

stant mass 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

gauge monitors canister vacuum

change during sampling.

sample inlet

The 0.3m x

1

/

4

-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 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.

5. Interchangeable critical orifice

An interchangeable ruby critical orifice allows you to control the flow with very high precision.

To select the correct critical orifice for your sample, see the table below. Available in stainless

steel, or Siltek

®

treated for optimum inertness.

Increase Accuracy & Efficiency

Our heating jacket can help you prepare your canisters

for sampling faster and more efficiently. The jacket’s

novel design ensures complete cleaning by heating the

canister and valve together. When used during the

analysis, it prevents condensation, ensuring more accu-

rate results. Two temperature settings, 75ºC and 150ºC.

Fits all canisters up to 6L in size.

Our easy-to-assemble passive sampling kits include all hardware required for field sam-

pling (except the canister). Our kits were designed to reduce the number of potential leak

sites and are available in seven flow ranges, and in stainless steel or with Siltek

®

surface

treatment. Individual parts also are available.
