Memmert Universal Oven UN750mplus – Advanced Natural Convection Heating for Medical and Laboratory Use

The Memmert Universal Oven Um UN750mplus is a high-capacity Class I medical device engineered for exceptional thermal performance and safety in professional laboratory environments. With a robust stainless steel build and large 749-liter chamber volume, this model delivers reliable, uniform heating for critical drying, sterilization, and warming applications. Featuring Memmert’s TwinDISPLAY control technology and extensive temperature protection systems, the UN750mplus ensures maximum control, stability, and user confidence.

Its natural convection mechanism provides uniform airflow without forced fan circulation, making it ideal for sensitive sample drying. Thanks to its adaptive PID controller, programmable settings, and real-time monitoring via AtmoCONTROL software, this oven enables precision-driven performance for demanding protocols.
