Instant results – Enzyme Indicators (EI’s) are an advanced validation tool in measuring bio-decontamination performance instantly. Reducing cost. Saving time. Improving efficiency.

Accurate, quantifiable data capture – Protak PR2A luminometer reader produces quantifiable readings that provide users with substantially more data about what can impact the bio-decontamination process. Enzyme Indicators can also act as ‘early warning system’, allowing routine performance monitoring to ensure that the bio-decontamination process has not drifted out of validated conditions.

Simple & easy to use – Our Protak EI tests are simple and easy to use so can be used by medical and pharmaceutical users and technicians alike. The enzyme indicator is used alongside Protaks PR2A luminometer, which reads and delivers results instantly.

Satisfies validation process requirements – EI use in bio-decontamination validation provide the information needed to clarify and understand the results quickly and easily to make data driven decisions.

100% performance assurance – EI’s are manufactured in an automated process which eliminates variability. Our Protak Enzyme Indicator luminometers offer more accurate quantifiable data.

Procurement cost savings – Our bespoke Athena software, luminometer readers and EI test strips compare favourably to other standard methods. EIs have a longer and stable shelf life and dramatically reduce production downtime.

Extensively tested by Public Health England (PHE) – Formally the executive agency of the Department of Health and Social Care, now UK Health Security Agency and Office for Health Improvement and Disparities. Extensively researched, tested before bringing to market.


Our Pharmaceutical working group includes AstraZeneca, Pfizer, Sanofi, Bayer, Baxter, Roche and Novo Nordisk – working on a consistent approach to the industry application of enzyme indicators in Hydrogen Peroxide Sterilisation and bio-decontamination process validation.
