CD53 / Automatic Record System. Chemical Indicator, double self-adhesive labels printed with reactive ink for Formaldehyde sterilization processes.

Chemdye® CD53 chemical indicator has been specially developed to control Formaldehyde sterilization processes. It consists of a double self-adhesive substrate of 29 x 22.5 mm printed with a highly sensitive innovative ink that turns from bordeaux-red to green when exposed to Formaldehyde. Its automated record system allows to control the cycle by identifying the load, the sterilization date and, eventually, the sterilizer (in case of having more than one).

Its self-adhesive properties offer the possibility of sticking it onto the load or any other material to be sterilized. Chemdye® CD53 chemical indicator has been specially designed to adhere onto non-woven wrappings, medical grade paper, polyester and polypropylene.

Chemdye® CD53 chemical indicators can be used either with or without Chemdye® CG3 Labeler. Using them with Chemdye® CG3 Labeler enables not only to speed-up the process of placing them onto the surfaces but to record important information related to the sterilization process.

Instructions for use

1. Peel off Chemdye® CD53 chemical indicator from the roll and stick it onto the package to be controlled.

2. Run a normal sterilization process.

3. Once the process has finished, open the sterilizer door, wait five minutes and remove the load. CAUTION: wear safety glasses and gloves  when removing the sterilized package.

4. Check the final color reached by Chemdye® CD53 chemical indicator. A green final color proves the chemical indicator has been exposed to Formaldehyde. IMPORTANT: this color change does not fully evidence the process effectiveness to achieve sterility. If the final color does not change, check the sterilization process.
