Memmert UN260plus Natural Convection Oven 256L, 115V

Features The Memmert UN260plus Natural Convection Oven 256L, 115V is designed to provide precise and consistent heating for a variety of laboratory applications. With a large internal volume of 256 liters (9 cu. ft.), it offers ample space for handling large batches or bulky materials. The oven operates within a temperature range of +5°C above ambient to 300°C, ensuring flexibility for both low and high-temperature tasks. The integrated TwinDISPLAY features a high-definition TFT-color display and a PID-microprocessor controller, allowing for easy adjustments and monitoring of temperature, airflow, and timing parameters. The oven’s two Pt100 sensors work in tandem for mutual monitoring, ensuring continuous temperature accuracy and reliability.

Safety and efficiency are paramount in the design of the Memmert UN260plus. The oven is equipped with AutoSAFETY, which includes over- and under-temperature monitoring with the ASF system, providing immediate alerts for any temperature deviations. Fresh air admixture is optimized through an electronically adjustable air flap, ensuring uniform heating. The durable stainless steel interior is easy to clean, corrosion-resistant, and reinforced with large-area heating on four sides, making it perfect for rigorous use in demanding environments. With a maximum chamber loading capacity of 661 lbs. and high-quality construction, this oven is an ideal solution for laboratories requiring robust and reliable thermal performance.
