Use these heaters as a dry, constant temperature source for various lab and research applications. All models have independent indicator lights to show main power, heater action, and over-temperature cut out. The “number of blocks accepted” on the ordering table indicate the number of single-width blocks accepted by each block heater. A heater that accepts two single-width blocks will accept one double-width block. Use three- and four-block models for high-throughput applications such as chemical oxygen demand (COD).

Use the calibrated rotary dial to set the temperature in 2°C increments. Heater offers excellent stability of ±0.05°C at 40°C. Dual-insert analog block heater holds up to two insert blocks or one 96-well block.

Please Note: Effective June 2022, the Techne Analog Block Heater Model number FDB02AP has now been rebranded Cole-Parmer under Model number BH-250-2-115. All the same great features and specifications, just with a new and improved look.
