Enzyme Indicators are presented as a small 5mm x 50 mm strip. At the end of this strip is a gauze which contains the Enzyme.
EI’s are handled as you would any other chemical or biological indicator. It is recommended that users wear sterile gloves for both placement and retrieval.
Placement of the EI’s is directly from the Tyvek pouch they are supplied in. Retrieval is immediately into the Luminometer Tubes which are also provided.
Good lab Practice is all that is needed to perform efficient readings, however, keep strips and reagents away from probable microorganism contamination where possible.
User PPE is a requirement as is the need to ensure no AK on gloves.
Enzyme Indicators have a shelf life of 9-12 months from the date of manufacture.
The PR2A reader can be seen here. It has a very small footprint and can easily be integrated into any lab.
Enzyme Indicators contain no bacteria and present no toxicological risk. On that basis they can be used in any part of any process.
The Enzyme is applied to the strip using a highly efficient and sensitive delivery method ensuring uniformity. The association of ‘rogue results’ as is the norm with BI’s is not applicable to EI’s.
They are manufactured to eliminate rogue results and include an optional onsite self-validation process.
The EI data is analysed through the Athena software which accompanies the PR2A Reader. The software can be installed onto any windows based laptop or computer.
Its simple and intuitive design with a traffic light system ensures a smooth user experience.
All BI and EI are dynamically affected by droplet size. Clear science exists to show how H2O2 efficacy and biological inactivation is affected by droplet size.
It is necessary to correlate and understand process performance and the subsequent effect on biological inactivation
EI’s can help to rapidly develop and optimise a decontamination cycle. There is no need to wait 7 days for results before making adjustments.
EI’s produce an immediate time saving when compared to BI’s. The results are available within 60 seconds of processing compared to a 7 day wait. Batches can be released with confidence without the need to wait.
EI’s remove the need to use BI’s in triplicate and also completely removes the need for Chemical Indicators. Consequently the Indicator costs for a decontamination cycle are significantly reduced.
Users typically benefit from gaining 2-4 weeks of additional production time per region per year, enabling capacity to be increased.
