Cole-Parmer™ BH-250 Series Dry-Block Heater

Description

Choose a heater, then blocks to suit your application needs.

• Precision-engineered heaters with excellent temperature accuracy
• Versatile range of interchangeable heating blocks work with many size sample tubes and plates
• Take up less storage space—lightweight and flat-top surface allow units to be stacked when not in use

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).
