% Heidolph Heat-On Multi-Well Holder 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.	% Heidolph Heat-On Safety Handles (2 pieces) • The Heat-On safety lifting handles are like the handles on a hot pan: essential for your safety. • Available as a pair, the safety lifting handles are easy to operate. Simply press the blue button to insert and remove the handles. • The bottom element, which is placed in the Heat-On Block or the Multi-Well holder, is made of stainless steel.	% Heidolph PTFE Safety Cover for 1 Liter Heat-On Block • The PTFE safety cover ensures even more safety for every application with a Heat-On Block for a 1 liter round bottom flask. • Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.	% Heidolph PTFE Safety Cover for 200 - 300 ml Heat-On Block • The PTFE safety cover ensures even more safety for every application with a Heat-On Block for a 200 - 300 ml round bottom flask. • Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.
