Cooling Heating Block Thermostat TK 23 for 2 Interchangeable Blocks
with programmable control
Product information
Precise Sample Temperature Control from -16°C to +90°C
The Heating/Cooling Block Thermostat TK 23 is suitable for molecular biology research, PCR preparation, enzyme kinetics, and pharmaceutical quality control. With space for two exchangeable blocks, microtubes, sample vials, centrifuge tubes, cuvettes, PCR plates, as well as microtiter and deep-well plates can be temperature-controlled in parallel – ideal for laboratories with varying vessel formats.
The temperature working range spans from -16°C to +90°C with an accuracy of +/-0.1°C. Up to 30 program steps and temperature curves with a process time of up to 99 hours can be stored. The heating output is 120 W, and the touch panel guides users through the menus in German and English via Smart Control.
The TK 23 combines flexible exchangeable blocks with programmable precision temperature control for everyday laboratory use. Learn more about cooling technology and cryotechnology for your laboratory. Request a quote now!
