CERAN^® - an extraordinary glass ceramic which is extremely resistant to breakage and changes of temperature, will not distort, permeable to ultra-violet light and also highly acid-resistant.

Construction: the low-mass CERAN^® plate is electrically heated over its full surface, and is embedded into a high-grade, stainless steel frame which is mounted on an internally insulated stainless steel housing.

The temperature control system is regulated by an electronic NiCr-Ni temperature sensor (regulation range between 50 and 500°C). The controller is built into a pressure-cast alumium casing. The heating time for 500°C is approximately 8 minutes. Four feet, which can be individually adjusted to an approximate  height of 8 mm, ensure wobble-free, horizontal stability.

Type 4A is equipped with additional sockets for 4 screw-in retort rods (situated 100 mm from each other).
