Hyde-Out Aldehyde Neutralizer neutralizes glutaraldehyde and OPA high level disinfectant / sterilant solutions and converts the solutions into non-toxic, nonhazardous waste. Once neutralized, solutions may be safely washed down the drain. Each quart (32 oz.) of Hyde-Out will neutralize up to 2 gallons of glutaraldehyde and 16 gallons of OPA. Correct measurement of the Hyde-Out solution is made easy using the tip-and-pour bottle with graduated label.
