Gas Sample Bags
SKC produced its first sample bag in the late 1970s. The bag was made of Tedlar® film and soon became the classic sample bag for VOCs. Over the last 30 years, SKC Tedlar bags have been the number one choice of professionals for grab air sampling. However, SKC has also introduced newer high-performance materials, which provide new standards of performance for storage stability and background in bag sampling applications.
SKC manufactures its sample bags out of clean top-grade films including SamplePro FlexFilm, (SKC proprietary film), FlexFoil, and FlexFoil PLUS. Seams are strong, evenly sealed, and leak tested.
Fittings
SKC sample bag fittings are not "off-the-shelf" industrial fittings, but are designed specifically for air sampling. The fittings, offered in a choice of materials, feature an efficient design that combines the hose/valve and septum fitting into one lightweight fitting. Use only PTFE tubing for bag sampling to prevent sample loss through adsorption to the tubing's inner surface. The fittings are 3/16 inch OD and suitable PTFE tubing is 231-9-23.
Possible applications for gas sample bags include:
- Indoor air monitoring
- Biogas/landfill monitoring
- Soil vapour monitoring
- Stack emissions
- Worker or process exposure
- Material testing
