Why Choose Thermax for Your Laboratory?
- Irreversible Proof of Temperature: Thermax strips provide a permanent, non-disputable record of the maximum temperature reached, which is critical for warranty validation and safety audits.
- Oil, Water, and Steam Resistance: Designed for harsh environments, these labels feature a protective polyester coating that makes them resistant to common laboratory fluids and high-pressure steam.
- Fast and Accurate Response: Utilizing specialized chemical compounds, Thermax indicators change color in less than one second once the specified temperature threshold is reached.
- No Batteries or Electronics Required: As passive indicators, they provide continuous 24/7 monitoring without the risk of electronic failure, making them ideal for long-term storage or remote transit.
- Extensive Temperature Range: With indicators available from 29 °C to 290 °C, Thermax provides a solution for everything from clinical sample transport to high-heat industrial ovens.
Frequently Asked Questions
1. How do I read a Thermax temperature strip?
Thermax strips typically feature a series of white or silver windows. When a specific temperature is reached, the window turns permanently black. The highest black window indicates the maximum temperature the surface achieved.
2. Can these labels be used inside an autoclave?
Yes, specialized Thermax indicators are designed to withstand autoclave environments, providing clear visual confirmation that the required sterilization temperature has been reached.
3. Are Thermax indicators accurate enough for lab work?
Absolutely. Standard Thermax strips offer an accuracy of +/- 1 °C for temperatures below 100 °C and +/- 1% for temperatures above 100 °C, meeting the requirements of most laboratory protocols.
4. What is the difference between a "reversible" and "irreversible" indicator?
An irreversible indicator (like most Thermax strips) stays black once triggered, providing a history of the heat event. A reversible indicator (like liquid crystal) changes color as the temperature fluctuates, showing the current temperature in real-time.
