Use of plastic materials in oxygen-measuring systems.
Seven types of plastics sometimes used in construction of physiological chambers were tested for their utility as devices employed to measure oxygen or oxygen uptake. They were equilibrated with air and exposed to hypoxic water, and the release of oxygen from the plastic to the water was measured. Nylon, acetal, and polyvinylchloride released the least amount of oxygen and thus are the most useful; acrylic and high-density polyethylene are less useful; polycarbonate and Teflon should be avoided.
