Operating Instructions

SKC All-in-One Low Flow Adapter/Single
Tube Holder

Cat. No. 224-27

Introduction

The SKC All-in-One replaces the SKC Single Adjustable Low
Flow Tube Holder and CPC for single-tube sampling with AirChek
Series and AirLite sample pumps. All required single-tube low fl ow
sampling accessories are included in one compact holder. The
built-in CPC maintains a constant pressure across the holder’s
needle valve for fl ow stability.

See Notes before calibrating and sampling.

2. Attach Tygon tubing to pump inlet.

3. Break tips off the sorbent tube to be used for calibration and
insert into rubber sleeve on holder (arrow on tube pointing
toward pump).

4. Use a calibrator to calibrate (set) fl ow rate through the
sorbent tube. Use a small fl athead screwdriver to turn fl ow
adjust screw on holder (counterclockwise to increase fl ow,
clockwise to decrease fl ow). See pump operating instructions

for details.

5. Remove tube used for calibration and repeat Step 3 using a
clean, labeled tube for sampling.

6. Thread protective tube cover onto holder’s threaded fi tting.

7. Use cover’s collar clip to attach holder on clothing in the
breathing zone.

8. Sample for the desired time.

9. When sampling is complete, remove sample sorbent tube
and cap. Insert sorbent tube used for calibration into sleeve
on holder. Use calibrator to verify fl ow rate has remained
within ± 5% of the set fl ow.

Notes

 Do not shut off fl ow completely with fl ow adjust screw or use an

oversized screwdriver to adjust fl ow; valve or thread seat damage
may result.

 Ensure sorbent tube fits snugly in rubber sleeve prior to

sampling to avoid any air leakage. Two sleeves, each a dif ferent
inner diameter (ID), are supplied.

 Calibrate before each sampling operation using the tube holder

and pump to be used for sampling.

 If the pump fl ow faults shortly after the holder tubing is attached

in Step 2, check that the needle valve is open by using a small
fl athead screwdriver to turn the fl ow adjust screw on the holder
slightly counterclockwise. If fl ow fault continues, check that the
two small holes on the bottom of the built-in CPC are not blocked.
See related bullet below.

 Two small holes on the bottom of the built-in CPC can become

blocked. Periodically inspect. Clean, if needed, with a small pick
and blow particles away with a puff of air.
