When selecting a heater, thermal accuracy and block uniformity are key. Techne’s new range of digital Dri-block heaters have a new look and a wide selection of instruments. Users can select two-, three- and four-block models for high-throughput applications, as well as a twin control unit for more complex experiments. Integrated timers can be set in one-minute intervals up to 99 h 59 min. The outer casing remains cool to the touch even at the maximum operating temperatures of 100C and 200C. They also have a safety shut-off feature, which is temperature adjustable by the user on some models. Bibby Scientific Limited
