Water and Oil Baths

Oil Bath ONE7


Product Description

Take a closer look at the Memmert Oil Bath ONE series. Promoting absolute safety for your laboratory and samples, even at high temperatures, through corrosion-resistant stainless steel, precise electronics and multiple layers of temperature protection.

The high temperatures that reside in the oil bath demand finely-tuned temperature control. The heating lies protected under deep-drawn and easy to clean ribs. The heating elements can therefore neither corrode nor become furred. Thanks to their positioning in the floor and side walls, a natural mixing of the temperature control fluid arises, providing more even temperature distribution within the oil bath.

In addition to the electronic overtemperature controller, a wide range of visual and acoustic identifiers ensure the smoothest test runs in your laboratory. From notifications that filling levels are too low, to signaling the end of a program – you’ll enjoy Memmert’s unique oil bath advantages.

Beautiful and functional, the ONE7 oil bath is made of Memmert’s scratch resistant stainless steel which is also hygienic, robust, and ever-lasting.
