Techne® Dri-Block® heaters have been providing a safe, dry, constant temperature source in the laboratory for 50 years. Now Techne® are proud to introduce the new, updated 2014 range offering market-leading choice, flexibility and specification. Dri-Block® heaters are a source of precision temperature control for general, routing applications and sensitive analytical procedures particularly suited to microbiology and clinical laboratories. They are designed for precise heating of test-tubes, microcentrifuge tubes, cuvettes and microtitre plates.Techne® Dri-Block® heaters cover the temperature range from ambient +5°C to 100°C or 200°C (depending on model) using machined aluminium alloy Dri-Block® inserts as the heat transfer medium. Independent indicator lights indicate mains power, heater action and over-temperature cut-out. An On/Off switch is mounted on the rear panel, together with the mains connector, a double fuse holder and adjustable over-temperature cut-out (depending on model).
