These sample bags feature a single stainless steel or PTFE fitting. The hose
connection, shut-offvalve, and syringe port with septum are all contained within
the single-port fiing.
Guidelines for Bag Sampling
1. Ensure that the bag material and fiings are appropriate for the compounds
to be sampled.
2. Use only PTFE tubing to connect the bag to the pump to prevent sample loss
by adsorption on tubing walls.
3. Before using, flush the bag thoroughly with purified air or nitrogen.
4. Analyze the sample within 24 to 48 hours after sampling. Long-term storage
of air-contaminant mixtures in bags is not recommended.
5. Do not ship sample bags by air unless the cargo cabin is pressurized.
6. Inflate bag properly (see Proper Bag Inflation for details).
7. Due to the physical properties of FlexFoil®bag material, minor crimps and
creases may appear on the bags during SKC manufacturing, quality testing,
and user handling. These marks only affect the aesthetics of the bag and not
its performance. FlexFoil bags exhibiting minor crimps and creases are not
subject to replacement or refund as functionality is not affected.
Notes and Cautions
• SKCsamplebagsaredesignedforsamplingairatatmosphericpressureonly.Aempting
to pressurize the bag will result in bag rupture and sample loss. Do not ship bag samples
by air freight in a non-pressurized cargo cabin. Bags can burst under such conditions.
• All federal and state packaging and transporting regulations apply.
• Do not use sample bags to sample compounds with boiling points > 249.8 F (121 C).
• SKC bag fiing valves are extremely durable but are not intended for use as handles or
hanging devices. This type of handling may damage the seal, causing leakage. This is
considered to be misuse and will void the SKC warranty.
• Failure to follow warnings and cautions voids any warranty.
• Sample bags are designed for single use only.

Operation
1. Flush the bag at least 3 times
with purified air or nitrogen
before use.
2. To fill a bag, connect PTFE
tubing from the exhaust port
of an air sample pump to the
stem on the bag fiing.
3. To open the valve, turn the knurled disc on the stem
counterclockwise a maximum of 2 revolutions. Turn on the
pump and sample as usual (see Proper Bag Inflation).
Do not use sample bags to sample compounds with
boiling points > 249.8 F (121 C).
4. When sampling is complete, turn offthe pump and close
the valve by turning the knurled disc clockwise until snug.
The outside diameter of the syringe needle should not
be larger than 12 gauge (0.109 inch).
Do not allow the syringe needle to puncture the bag
material when piercing the septum.
5. To withdraw samples using a needle and
syringe, carefully insert the needle into the
stem and pierce the septum centered in the
base of the syringe port.
Proper Bag Inflation
Avoid filling any bag to more than 80% of its maximum volume. At the end of the
sampling period, turn offthe pump and close the valve by turning the knurled disc
clockwise until snug.
