PTFE SAFETY COVER

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.

• 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
