Tristel is a manufacturer of infection control, contamination control and hygiene products. It has three principal activities:
- Hospital infection prevention and control under the Tristel brand
- Contamination control in the pharmaceutical and personal care industry under the Crystel brand
- Animal health infection prevention and control under the Anistel brand
The Tristel story began in 1993 when the founding shareholders developed a proprietary chlorine dioxide formulation to be used for the disinfection of flexible endoscopes to replace glutaraldehyde. Glutaraldehyde was at the time used universally throughout all hospitals in the United Kingdom, and indeed worldwide, for the disinfection of heat-sensitive medical instruments. However, it was known to be toxic.
