What are Summa Canisters?
A Summa canister is constructed of specially treated stainless steel designed for collecting a whole air sample.
Compared to Tedlar® bags and Sorbent Tubes, a Summa canister is far superior to use and does not require a separate pump. Opening the stainless steel valve allows the air sample to enter the canister over a specific period of time, without the need of any ancillary equipment. When the sample has been collected, the valve is closed and the canister is returned to the laboratory. The canister is prepared for sampling by evacuating the contents to a vacuum of approximately 30 inches of mercury (in/Hg).
