2 Event Non-Reversible Temperature Label

Two Event Non-Reversible Temperature Label.  Designed to monitor temperature on a microscope slide but has many other uses.  If the BOTTOM box changes from silver to black a temperature of 93°C has been reached.  If the TOP box changes from silver to black a temperature of 99°C has been reached. The label lets the end user know that the slide is at the optimum temperature range. 

The bottom portion has an area to write a code, initials or date. 
The label is waterproof.  Call and speak with a Thermal Advisor.
