Memmert UN30plus Natural Convection Oven 32L, 115V

Features The Memmert UN30plus Natural Convection Oven 32L, 115V is a versatile and precision-engineered solution for temperature control in laboratory and industrial settings. With a 32L internal volume, this oven provides ample space for a variety of sample sizes while maintaining a temperature range from +20°C to +300°C. The oven’s advanced TwinDISPLAY system, featuring dual high-definition TFT-color displays, allows for precise monitoring and easy adjustments. Equipped with two Pt100 sensors in a 4-wire circuit, the UN30plus ensures consistent temperature accuracy, protecting your samples through mutual monitoring and error prevention.

This oven also features natural convection for uniform heat distribution, ideal for delicate samples, along with a pre-heated fresh air admixture controlled by an adjustable air flap for optimal temperature stability. The digital timer, adjustable from 1 minute to 99 days, offers flexibility in various applications, while the AutoSAFETY system provides integrated over- and undertemperature protection for maximum safety. The easy-to-clean stainless steel interior, reinforced by ribbing, is corrosion-resistant, making the Memmert UN30plus both robust and reliable for continuous lab use.
