Hello, This is a correction to a previous posting. The Stephens Fire Science Laboratory at the University of California, Berkeley (http://www.cnr.berkeley.edu/stephens-lab/), is looking for a Li-Cor 6200 gas respiration chamber. The production of this model has been discontinued. If somebody has information on where we can buy/borrow/have a used chamber please email (d...@berkeley.edu). This is an older model licor instrument and we are hoping somebody has one sitting in their lab and they don't mind parting with it. Thank you very much.
