Dual Stainless Steel Fitted Bags
The 231 and 237 Series sample bags feature dual stainless steel fi tt ings – an inlet
valve for fl ushing and fi lling and a PTFE-lined septum fi tt ing for removing samples.
Guidelines for Bag Sampling
1. Ensure that the bag material and fi tt ings are appropriate for the compounds
to be sampled.
2. Use only PTFE tubing to connect the sample bag to the pump to prevent sample
loss by adsorption on tubing walls.
3. Before using, fl ush the bag thoroughly with purifi ed air or nitrogen.
4. Analyze the sample within 24 to 48 hours. 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.
Maximum Operating Temperature
Do not exceed these specifi cations.
• 231 Series Bags: 225 F (107 C) due to fi tt ing O-ring temperature rating
• 237 Series Bags: 140 F (60 C) due to the SamplePro
temperature rating
Do not use sample bags to sample compounds with boiling points > 249.8 F (121 C).
SKC sample bags are designed for sampling air at atmospheric pressure only.
Att empting to pressurize the bag can 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.
Failure to follow warnings and cautions voids any warranty.
Sample bags are designed for single use only.
