FlexFoil Bags FAQs
SKC FlexFoil® Grab Bags provide light and moisture protection for
low molecular weight compounds such as hydrogen that are unstable
when collected into standard Tedlar bags. Use a low flow air sample
pump with exhaust port, such as the SKC 222 Sample Pump (Cat. No.
222-3) or Grab Air Sample Pump (Cat. No. 222-2301), with SKC FlexFoil
Grab Bags.
The FlexFoil Grab Bag Advantage
Prevent permeation: Four layers of foil material prevent
permeation in and out of the bag.
Inert: The inside surface is inert, minimizing absorption
and adsorption of compounds.
Strong: SKC FlexFoil Grab Bags have strong, evenly
sealed seams making them ideal for mailing or shipping to a laboratory
for analysis.
The four-layer
foil material is stronger than Tedlar.
Light-protective: Protect light-sensitive compounds
without the use of an outer container or black Tedlar.

- Transferring calibration gas from lab to instrument
- Preparing calibration mixtures
- Assessing exposure from leaks and spills
- Indoor air studies (CO, CO2)
- Carbon dioxide in workplace atmospheres (OSHA ID-172)
- Carbon dioxide (NIOSH 6603)
- Carbon monoxide (OSHA ID-210 ‡)
About FlexFoil Grab Bag Fittings
SKC FlexFoil Grab Bags are available with an easy-to-use single septum fitting
made of stainless steel or polypropylene. Choose the fitting that best
fits your application.
 |
Stainless Steel Fitting: This
unique, patented fitting combines the hose/valve and septum fittings
into one easy-to-use unit. Fitting construction prevents leakage
and
ensures that the sample is exposed to only inert materials. This fitting reduces
the cost and overall weight of using stainless steel when stainless steel fittings
are specified.
|
 |
Polypropylene Fitting: The industry standard,
this patented lightweight, inert fitting combines the hose/valve
and the septum
holder into one compact fitting. |
