What is it indicated for?

SPOROX™ Test Strips provide a rapid, convenient semi-quantitative

means of indicating whether effective concentrations of hydrogen

peroxide are present in SPOROX® Sterilizing and Disinfecting

Solution. The SPOROX™ Test Strips indicate concentrations of

hydrogen peroxide but do not confirm disinfection or

sterilization.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
