INK CHEMISTRY & STABILITY

Users can find that with some test packs there is significant sensitivity variation between successive batches of product - BUT NOT WITH THE PROPPER ONCE-A-DAY®II TEST PAK.

Users can find that with some test packs, the indicator sheets have unstable, inadequate indicator inks that can change back to the unprocessed colour or that can darken when stored after use - BUT NOT WITH THE PROPPER ONCE-A-DAY®II TEST PAK.

The constant level of sensitivity and the test sheet colour stability of the Propper product helps the hospital avoid potentially serious legal consequences.

The Propper indicator ink used on the new ONCE-A-DAY®II test sheet is totally stable. There is no change in the colour after processing. An essential requirement for the legal archiving purposes.

A stable ink like Propper’s indicates that this chemistry is far more reliable and trustworthy than one that may routinely change during storage.
We have documented our colour stability for at least twenty years…… can anyone else give you that guaranteed claim?

Propper Manufacturing Company Inc. uses a specially designed, microprocessor-controlled, test steriliser that was constructed using state-of-the art engineering technology to meet the exacting requirements for EN 867-4 testing. The testing criteria for EN 867-4 are very demanding and beyond the testing capability of many facilities and almost all regular production autoclaves.

This highly specialised, very costly test sterilizer is solely used by Propper to test and validate the performance of the ONCE-A-DAY®II TEST-PAK to the EN 867-4 requirements. This again demonstrates Propper’s commitment to the production of ACCURATE and CONSISTENT products that COMPLETELY and RELIABLY meet the required standards.

MEDICAL PRODUCT QUALITY CONSTRUCTION
