Memmert UN55plus Universal Oven, 53 litres, TwinDISPLAY, natural convection, 300 °C

Programmable laboratory standard for sensitive samples: Memmert UN55plus

With a capacity of 53 litres, the Memmert UN55plus universal oven is one of the most sought-after sizes for everyday laboratory use. It offers the perfect balance between space-saving external dimensions and ample internal space. As the unit operates using natural convection (without a fan), heat transfer takes place completely free of turbulence. This makes the UN55plus the ideal solution for the gentle drying and temperature control of fine powders, light granulates, paper or biological samples, which could be stirred up or dried out by an air flow.

TwinDISPLAY: Intuitive programming for demanding processes

As a model in the Premium Series, the UN55plus offers full programmability. Complex temperature ramps and process cycles can be created with ease via the intuitive TwinDISPLAY, featuring two high-resolution TFT touchscreens. The electronically controlled exhaust air flap regulates the fresh air supply precisely in 10% increments. A major advantage for sensitive batches is the HeatBALANCE function: this allows you to adjust the heating power specifically between the upper and lower sections of the cabinet, for example to compensate for asymmetrical loading.

Redundant safety and comprehensive documentation

Two independently operating Pt100 sensors (DIN Class A) ensure maximum process reliability and validatability (GMP/GLP). If one sensor fails, the second seamlessly takes over temperature control. The integrated AutoSAFETY system reliably protects your valuable samples through visual and audible alarms, as well as automatic heating shutdown in the event of deviations. All process data is stored in the internal data logger and can be downloaded via USB or Ethernet using the supplied AtmoCONTROL software.
