Twindicator 8" Perforated Chemical Indicator
Twindicator® Perforated Steam Indicators are Type 4 chemical indicators. They monitor steam sterilization cycles at 250°F (121°C) and 273°F (134°C). Place Twindicator® strips inside of pouches, trays, or other packages. The ink on the strip turns from off-white to black upon exposure to the steam sterilization process.
How to Use Twindicator® Perforated Steam Indicator Strips
Place the Twindicator® indicator strip in the package you want to sterilize. Optionally, you can tear each strip in half to create a shorter internal chemical indicator.
Next, process the package according to your steam sterilization cycle.
Once the sterilization cycle is complete, remove the package and examine the Twindicator® indicator.
If the indicator is completely black, then the contents of the package have been properly sterilized. Conversely, reprocess packages if the indicator does not change color.
Features & Benefits:
Perforated for flexibility: Each 8″ strip tears in half easily, creating two 4″ strips. This allows you to customize the strip length to fit your needs. Measuring 1.5 cm wide by 20 cm long (0.625 in wide by 8 in long), each indicator strip has chemical indicator ink printed on it.
Easy to read: Twindicator® features a single stripe across the strip with an off-white to dark brown/black color change after exposure to a steam cycle.
