Abstract

1316078 Sterilization indicator A W CHAPMAN 4 April 1972 [30 April 1971] 12354/71 Heading A5G An indicator for indicating completeness of sterilization in processes using steam and formaldehyde comprises a carrier, e.g. a piece of porous paper or fabric, on which is deposited a sulphite and a pH indicator having a change point on the alkaline side of neutrality. The device may be enclosed within a porous cover or may also contain a deposited bisulphite, both modifications serving to delay the change in the indicator, which operates by detecting alkali released by the reaction of formaldehyde with sulphites.
