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).

Independently control the temperature of two blocks with dual-control digital heaters—ideal for multiple users or for applications where samples have to be transferred between temperatures very quickly. Heater heats up from 25 to 100°C in 8 minutes and achieve temperature stability of ±0.1°C at 37°C. Quickly set and view temperature on the 5-digit LED. Side panels help dissipate heat from the outer surfaces for safe handling. Adjust the countdown timer between 1 minute and 100 hours in 1-minute increments. Once the countdown timer has completed, it will beep and the unit will begin to cool to ambient temperature.

Please Note: Effective June 2022, the Techne Digital Block Heater Model number DB100/2TC/115 has now been rebranded Cole-Parmer under Model number BH-250DC-2-115. All the same great features and specifications, just with a new and improved look.
