Air Sample Pump Operating Instructions (PDF)
The Grab Air Sampler is a hand-held battery-operated sample pump designed
to fill bags at 1 L/min efficiently and reliably. A simple "turn on and
sample" pump, Grab Air operates on a disposable 9-volt alkaline battery.
An LED indicates low battery. The Grab Air Sample Pump is recommended
for sample bags up to 10 liters.

Principle of Operation
The Grab Air Sampler pulls air containing the sample into the pump at approximately
1 L/min and immediately exhausts it into a sample bag connected to the pump
with PTFE tubing. Sampling is complete when the bag is properly filled (see
Bag Sampling).
Bag Sampling
Sampling Tips
- Use only PTFE tubing and a PTFE-lined septum for bag sampling
to prevent sample loss.
- Flush bags thoroughly with purified air or nitrogen before use.
- Do not use bags to collect unstable or highly reactive compounds.
- Do not ship sample bags by air unless the cargo cabin is pressurized.
- When sampling for CO or CO2, use SKC
Foil Grab Bags (245 Series).
- Long-term storage of compounds in Tedlar bags is not recommended
as chemicals can adsorb onto the inside surface of the bag.
- The O-ring in the sampling valve on SKC sample bags withstands
temperatures up to 200 F (93.3 C). Use this as a sampling guideline.
- Avoid filling any bag more than 80% of its maximum volume.
Visually inspect the bag as it is filling to determine when sampling is complete.
