Stainless Steel

For many years exterior textured stainless steel has been the unmistakable feature of Memmert ovens, incubators, and climate chambers in laboratory and light-industrial settings. Memmert equipment exemplifies functional design in its most elegant and hygienic form, while still being scratch resistant, robust and durable.

Stainless steel is the ideal material for temperature control chambers and heating baths. It is particularly corrosion-resistant, hygienic, robust and recyclable without question.

Wherever Memmert ovens and heating baths are used, the superiority of high-quality stainless steel is undeniable in comparison to others that utilize coated sheet steel, which can corrode very quickly when in constant use.

For the outer housing of all Memmert appliances, textured stainless steel is used (rear walls are zinc-plated sheets). The inner chamber, sliding shelves/grids, housing, interior basin and accessories for every heating bath, stainless steel of class W-St. 1.4301 (ASTM 304) is used. Since aggressive substances are frequently used in the vacuum drying oven, the inner chamber and thermoshelves are made of stainless-steel W-St. 1.4404 (ASTM 316L), and the tubing is made of stainless-steel W-St. 1.4571 (ASTM 316i).
