Heat-On Pear Block-Anodize Aluminum Repair Kit - 200ml for Metal Restoration & DIY Projects | Perfect for Automotive, Motorcycle & Home Repair

It is accepted that oil baths and heating mantles are no longer the preferred choice of chemists to heat round bottom flasks. The risk of oil fires and injury from hot oil spills, plus the mess associated with the use of oil means that oil baths no longer represent safe working practice in labs. Heating mantles are expensive, difficult to clean, do not respond well to spills and often create hot spots when heating. Therefore, scientists are increasingly turning to specially designed aluminum blocks located on stirring hotplates to heat standard round bottom flasks.

Heat-On weight-saving design reduces the mass of the block to be heated

Blocks feature a proprietary well design that eliminates cracking of flasks

They have two probe holes for insertion of temperature probe/s

Blocks can be used up to 200°C and 260°C for short periods

All Heat-On blocks are manufactured from solid aluminum providing excellent, even heat transfer to the entire block, preventing hot spots
