Residual ethylene oxide: levels in medical grade tubing and effects on an in vitro biologic system.

The level of residual ethylene oxide after sterilization was evaluated as a function of aeration time for three medical grade tubings. Toxicity resulting from residual ethylene oxide was determined in an in vitro tissue culture system utilizing L-cells. The absorption and desorption of ethylene oxide from poly(vinyl chloride) and polyether-polyurethane… CONTINUE READING
