Memmert UN55plus Natural Convection Oven 53L, 115V Setting Temperature Range +20°C to +300°C Convection Type Natural Convection Chamber Volume 53L Features
The Memmert UN55plus Natural Convection Oven 53L, 115V offers exceptional precision and control for a wide range of laboratory applications. With a working temperature range from +20°C to +300°C, this oven ensures stable and uniform heating, ideal for sensitive sample preparation and material testing. Equipped with TwinDISPLAY, a state-of-the-art dual high-definition TFT-color display, the oven provides intuitive control of temperature, time, and air flap settings. The natural convection system guarantees gentle airflow and uniform heat distribution, making it perfect for delicate samples that require a stable environment. The oven’s interior, crafted from easy-to-clean stainless steel, is reinforced with deep ribbing for durability and even heat distribution.
Safety and efficiency are core features of the Memmert UN55plus. It comes with 2 Pt100 sensors for precise temperature monitoring and dual overtemperature protection through an integrated mechanical and electronic system. The oven's AutoSAFETY feature adjusts the heating performance to maintain accuracy, while its SetpointWAIT function ensures that processes only begin once the desired temperature is achieved. Additionally, its programmable digital timer, with adjustable settings ranging from 1 minute to 99 days, offers workflow flexibility. With a 53L capacity, robust design, and advanced programming options, this oven is a reliable choice for laboratories focused on consistent, safe, and high-quality results.INCLUDED: TheMemmert UN55plus Natural Convection Oven 53L, 115V includes:
