Magnetic stirrers with heating and motor

For Hotplates with 135mm diameter.
The reaction block allows syntheses to be carried out in round flasks without using an oil or sand bath. The reaction block ensures safety at work and preventing oil baths and heating mantles from over heating in your lab. The messy oil clear-ups that result from changing oil or removing flasks from an oil bath will be minimised. This system ensures optimal heat transfer from the heating plate directly into the medium. Uniform mixing is also guaranteed because there is no interference to the magnetic field from the aluminium blocks. Reaction blocks are available in four standard sizes.

• Syntheses in round flasks without oil bath
• Uniform mixing
• High-precision thermal conduction directly into the reaction block
• Safe and clean working

These attachments are by far the safest, fastest and most efficient method for heating and mixing solutions in round-bottom flasks from 10 ml to 5L. Heat-On fits precisely to every flask, thus insuring maximum surface contact and fast heat transfer. This eliminates the need for oil as a heat conductor.

• This unique design prevents glass breakage and protects from spilled chemicals or solvents
• The high temperature range provides unlimited safety for applications up to 260°C
• A unique PTFE coating on the aluminum Heat-On body allows for superior chemical resistance and many years of service life
• 150 ml of water boils in less than 11 minutes
