Cole-Parmer® Analogue Heaters - BH-250-2, BH-250-3 

Cole-Parmer® block heaters have been providing a safe, dry, constant temperature source in the laboratory for 50 years, offering market-leading choice, flexibility and specification. 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. Cole-Parmer® block heaters cover the temperature range from ambient +5°C to 100°C or 200°C (depending on model) using machined aluminium alloy 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 and a fuse holder.
