The TB2 Thermoblock is a dry block heater for incubation in tubes of up to 50 ml and up to 130°C. Designed by Analytik Jena, the TB2 Thermoblock has a precise temperature control which incubates the reaction tubes at fixed temperatures. This temperature control is achieved with a Pt1000 microsensor which obtains outstanding block uniformity. The TB2 Thermoblock has a dual block design which means that either two single blocks or one combi block can be heated. The waterproof front panel has an ergonomic design which facilitates temperature readings and data entry. The TB2 Thermoblock benefits from having a central multifunctional control knob which starts the block and count down timer, has different calibration options, activates the temperature deviation alarm, uses the delay function, and chooses the optional external temperature sensor.
