Designed to heat round-bottom flasks, the heating block system with interchangeable inserts can be used with various Cole-Parmer hot plates and hot plate stirrers with 6" x 6" top plate. The heating block system offers two sizes of base plates (small and medium) which can accommodate up to three block inserts each. A third larger base plate features heat-resistant handles and accepts a single block insert for flasks up to 500 mL. Chemical- and solvent-resistant anodized block inserts provide a safe method for synthesis of single or multiple reactions and offer equal or better heating performance than silicon oil. The low-well provides excellent temperature transfer without compromising the view of the reaction or risk of cracking the glassware. Each base plate features a hole to house a temperature controller probe.

Please Note: Only use with Cole-Parmer metal top hot plates.
