Universal Oven UN - Memmert

Lab Oven for Universal Use

The Memmert Universal Oven UN is a heating and drying oven designed for precise drying, heating, ageing, burn-in and hardening in research, science, industry and quality assurance. With a temperature range up to +300 °C and natural convection, the UN delivers safe, reliable performance across a broad spread of laboratory and industrial applications.

Precise, Even Heating

Natural (gravity) convection combined with electronically controllable air exchange rates and air flap position gives the UN consistent results. Pre-heated fresh air entering the chamber helps prevent temperature fluctuations, so samples experience a stable, uniform environment throughout the process.

Flexible Controller Options

The UN is available with two controllers. SingleDISPLAY offers intuitive, easy-to-use operation, while TwinDISPLAY adds programmable temperature and air-exchange ramps plus an integrated data logger that interfaces with Memmert’s AtmoCONTROL software for programming, monitoring and documentation.

Built to Last

A corrosion-resistant, easily cleanable stainless steel interior and a structured stainless steel housing make the UN durable and hygienic. The range is CE, UL and GS certified and backed by a 3-year worldwide guarantee.

Nine Sizes

With nine model sizes from roughly 32 to 1060 litres, there is a Universal Oven UN to match almost any throughput - from a compact UN30 bench unit to large-capacity UN450 and UN750 models.
