Why does a TempGuard message appear during a CEM EasyPrep Laboratory Equipment run?
- LLeslie BrewerAug 11, 2025
A TempGuard message might appear because some vessels are hotter than others, or because TempGuard variables are programmed incorrectly (if your software version is older than 1.49). To solve this: * Follow the “Liner Bake-out Procedure” to reduce temperature differences in liners. * Avoid mixing old and new liners; run them in separate turntables. * If your software version is older than 1.49, adjust your TempGuard settings. Set the TempGuard limit at 30 °C above the control temperature if the control temperature is below 230 °C, or 20 °C above if it's above 230 °C. For digesting organics with HNO3, limit TempGuard to 250 °C; for HPO/HSO applications, limit it to 300 °C.
