Precise, reliable and safe. Memmert heating ovens and drying ovens are used in research, industry and medicine for a variety of applications: heating, drying, tempering, testing, ageing, sterilisation, burn-in test, annealing, curing, polymerisation, vulcanisation, heated storage and conditioning. Since 1947.
32 litre or 1060 litre chamber volume? Simple drying tasks or high demand for programming and documentation? A Memmert heating oven and drying oven suits any application thanks to the wealth of communication interfaces, configuration and options. It meets the strict requirements of DIN 12880:2007-05 and has a maximum of safety functions.
Heating ovens or drying ovens are used for a variety of applications.
The chamber load is exposed to defined temperatures at atmospheric pressure in the interior of a drying oven or heating oven. Thermal energy is transferred to the chamber load by convection and radiation.
Heating a Memmert heating oven is something very special. It takes place via a unique, full-surface heating system (all-round heating) behind the interior walls. In contrast to other heating systems such as ring heaters or heating coils, this ensures excellent heat transfer as well as optimum temperature distribution and uniformity even when fully loaded thanks to the direct contact between the heating ribs and the sliding shelf.
Drying takes place faster the higher the temperature, and the drier the air within the chamber. A drying oven or heating oven is usually available either with natural convection or forced convection. In the version with forced convection, heat transfer (convection) and air exchange are accelerated via a switchable fan, thus promoting homogenous temperature distribution in the interior. The vacuum drying oven VO is particularly recommended for the gentle drying of powders, granulates or electronic components. The boiling point is reduced by the vacuum in the vacuum drying oven, which means that the chamber load is heated or dried at lower temperatures.
The moisture content of a material/sample is measured using the drying oven method. It is a measurement method for gravimetric analysis, or more precisely thermogravimetric analysis, in which the content of liquid and volatile substances is determined by mass. A precisely weighed sample is exposed for a certain drying time at a certain temperature. The drying loss is then determined by weighing it again and the moisture content is obtained as a percentage. Even if a large number of rapid tests are available, for example for determining the humidity content of fuels, grain or foodstuffs, the drying oven method is the prescribed test method or the approved reference method under many standards. In some tests (e.g. paper and cardboard) the samples are conditioned in a standard climate before the thermogravimetric test.
