McKesson OPA/28 Test Strips, Concentration Indicator, Single-Use, 50 Count, 2 Packs, 100 Total

Single-use McKesson OPA/28 test strips are chemical concentration indicators that test whether the concentration of ortho-phthalaldehyde (OPA) is at a safe level in OPA/28 disinfectant solution. You can use these strips to check the minimum effective concentration (MEC) of the OPA/28 solution before each use to ensure your solution is still effective at disinfecting equipment that is not suitable for sterilization. Additionally, the disinfection reaction time of the sanitizer concentration test strips is quick. With their large indicator pads, these test strips are also easy for you to read. Using these single-use McKesson test strips helps you ensure a healthy environment. After dipping the strips in OPA/28 solution for 3 seconds, wait 90 seconds and interpret results with the help of the comprehensive color identification comparison chart on each bottle. With a shelf life of up to 18 months, the disinfection test strips will last you a long time when left unopened.
