Radleys Heat-on™ blocks

For heating and stirring of one or two 10 ml to 5 liter round-bottom flasks

Say goodbye to oil baths and heating mantles! Heat-On allows you quick and safe personal heating and stirring of your round-bottom flasks, without the risk of fire or personal injury—and let’s not forget the messy cleanup.

These Teflon^®-coated, chemical-resistant blocks fit on all common hotplates (e.g., Radleys Carousel, Heidolph, IKA, etc.) up to 145 mm in diameter, and their design ensures even heating without the worry of cracked or breaking glass. Flask and tube inserts are available to accommodate a wide variety of sample sizes—and if you need to transport your sample(s) immediately after operation, the optional carry handles allow you to do so, safely and easily.
