Replace oil baths and jacket heaters in your lab and reduce the risk of fire. Heat-On blocks are by far the safest, fastest and most efficient method for heating and mixing solutions in round bottom flasks from 10 ml to 5 l.
• Highest Level of Safety
Increased occupational safety and fire protection: The elimination of oil baths prevents accidents, fires and contamination. The unique design prevents glass breakage and thus minimizes the risk of possible cutting injuries and leaking liquids. The high temperature accuracy offers maximum safety for applications up to 260 °C.
• Superior Ease of Use
The temperature can be measured conveniently and precisely in the medium or directly at the reaction attachment. No oil is required as a heat conductor, as the attachments snugly enclose the flasks. The cleaning effort is minimized. The PTFE coating offers the highest resistance to chemicals and correspondingly many years of use.
• Lasting Reduction of Cost of Ownership
The simplified handling minimizes process times and increases sample throughput: 150 ml of water are brought to the boil in less than 11 minutes. In addition, the 66 % faster heating times compared to conventional oil baths save on energy costs.

Protects the magnetic stirrer against splashes and dripping water.

Includes support rod and attachment with cable inlet.

The optionally available temperature sensor Pt 1000 achieves precise values without any temperature fluctuations.
