TLC Plate Heater biostep ® (DESAGA) Thermoplate S plus The Thermoplate S plus is an electronically controlled hotplate for detection reactions in TLC/HPTLC and for precise heating and drying operations in the laboratory. Advantages: Changing colours from green to red at increasing temperatures Timer function with acustic signal Program control with saving up to 9 programs The unit operates with a platinum resistance thermometer. Temperature readout is made on a coloured touchscreen which changes from green or blue to red at increasing temperatures. This means the user can visually see if it is safe to touch the plate or not. An accustic signal informs the user as soon as a defined time or requested temperature is reached. The heating surface is made of high conductivity aluminium that - together with the ultralarge area of the heating element - ensures a uniform temperature distribution Technical specifications: Temperature range: 25-200 °C Heating area: 240 x 240 mm Heating rate (at 50 °C): 10 K/min Fluctuation range of temperature: 2 K
