INHALATION TOXICOLOGY FORUM We are looking for a few good inhalation chambers CH Technologies has received a request for Rochester or Laskin (NYU) type whole body inhalation chambers. These should be stainless steel and glass with the usual fittings. The units sought may be currently installed, not in use or otherwise surplus. We hope to find a home for a number of one or two meter chambers. Mix and match is possible but 4 large (2 cubic meter) or 8 smaller (1 cubic meter) chambers are the preferred number. All offers will be held in confidence. If you have such an inventory that you no longer need and would like to sell or donate, contact the Editor, Rudy Jaeger at "jaegerr@bellatlantic.net"
