Gas and Vapour Sampling Accessories
SKC offer a range of gas and vapour sampling accessories to complement the range of air sampling pumps.
Constant Pressure Controller (CPC)
A CPC is a device which allows a sampling pump to operate at low flow rates and with the optional adjustable low flow tube holders.
The CPC is placed inline between the adjustable low flow tube holder and the pump inlet, and regulates the specific amount of pressure to be maintained across the needle valve(s) on the supply (pressure) end of the sampling train. During sampling a valve inside the CPC opens and pulls additional air into the train on the pump (vacuum) end of the CPC as needed, to maintain the CPC-specified pressure across the needle valve(s). Note that the All-in-One low flow tube holder (224-27) is available which combines a CPC with a single low flow adjustable tube holder.
| Description | Part Number |
| CPC for Sidekick and AirChek series pumps (3000, ESSENTIAL, ESSENTIAL+, CONNECT, XR5000, TOUCH) | 224-26-CPC |
| CPC for AirLite and Pocket Pump TOUCH* pumps | 224-26CPC-10 |
* Not required when using a single adjustable low flow tube holder with a Pocket Pump TOUCH pump

Adjustable Low Flow Tube Holders
These products enable a sampling pump to be used with up to 4 sorbent tubes at the same time, either the same tube type running at different flow rates, or with different tubes running at the same or different flow rates.
Note that when using a single tube with the Pocket Pump Touch the Non-Adjustable Low Flow Tube Holder is used.
| Description | Number of Tubes | Part Number | |
| Single adjustable low flow tube holder (all pumps except Pocket Pump Touch) | 1 | 224-26-01 |  |
| Double adjustable low flow tube holder | 2 | 224-26-02 |  |
| Triple adjustable low flow tube holder | 3 | 224-26-03 |  |
| Quadruple adjustable low flow tube holder | 4 | 224-26-04 |  |
| All-In-One low flow single tube holder Combines an adjustable low flow tube holder and Constant Pressure Controller (CPC) in one unit. Not for use with Universal Pumps. |

Protective Tube Covers
These protect the ends of the tube for storage and transit. The appropriate tube cover must be selected by matching the Tube Cover type in the Sorbent Tube Selection Charts. Note that tube covers Types A to D are for use with SKC Adjustable Low Flow Tube Holders only. Collar clips are attached for convenience.
| Tube Cover | Size OD x Length | Part Number | |

| P | Low-volume PUF** (polyurethane foam). Note: do not use an adjustable low flow holder | 224-29P |  |
| H | 16mm OD. Specifically for use with sorbent tubes 226-142 and 226-177 | 224-29H | |
* OSHA Versatile Sampler (OVS) tubes are typically used at a flow rate of 1 L/min provided by a personal sample pump. The special OVS tube holder is designed to accommodate the 13 mm diameter of SKC OVS tubes, provide a convenient clip to attach the tube in the breathing zone, and protect the tube during sampling. Includes 0.9 m (3ft) of tubing.
** Low-volume PUF (polyurethane foam) tubes are typically used at a flow rate of 1 to 5 L/min provided by a personal sample pump. Therefore, a special tube holder is used in place of an adjustable low flow holder that only allows flows to 500 ml/min. The low-volume PUF tube holder is also specially designed to accommodate the large 22 mm diameter and long 100 mm length of SKC low-volume PUF tubes. Includes 0.9 m (3ft) of tubing.

Tube Breakers
| Description | Part Number | |
| All-in-one Tube Breaker, in stainless steel for 6, 7, 8, and 10 mm OD tubes. Heavy duty cap rotates to expose the desired size opener and to retain glass tips for disposal. | 226-03-055 |  |
| Tube Scorer/Breaker, for 6 mm OD tubes; scores and breaks end tips off glass tubes leaving a clean, smooth opening and retains broken tip ends for safe disposal | 810-722 |   |
Polyurethane Foam (PUF) Tubes
Polyurethane Foam (PUF) tubes are available in low volume or high volume versions:
- The low volume PUF tubes (22 x 100 mm) are for measurements up to 24 hours at flow rates between 1 to 5 L/min.
- The high volume PUF tubes (65 x 125 mm) are designed for use with high volume samplers for ambient air sampling of organochlorine pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs).

Chromosorb Sorbent Tubes
Chromosorb® is a porous polymer sorbent and is used to trap low-boiling hydrocarbons, benzene, labile compounds, and volatile oxygenated compounds. Chromosorb® 106 is a hydrophobic sorbent and the least polar polymer in the Chromosorb family and is functionally similar to Anasorb® 727.
Chromosorb® 102 is used to trap chlorine-containing pesticides.
