Heat-On makes your chemistry safer, cleaner and faster

Replace messy oil baths, heating mantles and avoid spills. Heat-On accepts vials, tubes and flasks from 10 ml to 5 litres. Fits on all leading hotplate brands with a 145mm Ø top plate; optional adapter plate for 135mm Ø top plates

  • Unique well design eliminates cracking of flasks.

    Blocks feature two probe holes for added convenience. Optional and detachable lifting handles. Optional PTFE Safety Covers reduce risk of user touching hot blocks.

  • Solid aluminium blocks provide even heating

    Lightweight design allows rapid heating. Use up to 260˚C. For vials, tubes and flasks from 10 ml to 5 litres, plus option for Florentine (pear-shaped) flasks.

  • Choice of block finishes

    Fluoropolymer coating gives superb chemical resistance. Anodised finish is durable, lower cost option.

  • Heat-On heats hotter, faster

    Heat-up tests have shown Heat-On can boil a 250 ml flask of water in under 11 minutes, faster than an oil bath and faster than other blocks.

Safer

Safer

The risk of oil fires and injury from hot oil spills, plus the mess and cost associated with the use of oil means that oil baths no longer represent safe working practice in labs.

Cleaner

Cleaner

Heating mantles are expensive, difficult to clean, do not respond well to spills and often create hot spots when heating.

Heat-On Globe

Greener

Scientists are increasingly turning to specially designed aluminium blocks located on stirring hotplates to heat standard round bottom flasks.

Heat-on

Oil baths are messy, dangerous and costly

  • Oil will discolour and degrade with repeated heating and contamination from chemicals, water and general debris.
  • Degradation results in a dangerous lowering of the oil’s flashpoint as well as increased smoking and fumes.
  • Oil should be regularly replaced to maintain a safe working environment.
  • Disposal of oil waste must be done in an environmentally and safe way, with associated costs.

Heat-On Safety Covers

Heat-On PTFE Safety Covers

Reduce the risk of users touching the ‘hot’ Heat-On block and lower energy consumption
PTFE Safety Covers slide over the top of your existing Heat-On block, acting as a second skin, the temperature probes and handles can be used as normal. The non-stick PTFE surfaces can be wiped clean with ease.
Heat-on-benfits

Benefits

  • Reduces the temperature of exposed surfaces by up to 50%
  • PTFE insulation reduces energy consumption by 15%
  • Chemically-resistant PTFE withstands temperatures up to 260˚C
  • Prevent accidental spills of solvents on to hot surfaces
  • Fits easily over existing Heat-On Blocks
  • PTFE Covers for all popular Heat-On sizes

Improved safety

Manufactured from solid PTFE, these Safety Covers provide an insulating barrier between the user and the ‘hot’ Heat-On blocks. Tests show that the temperature difference between the outside surface of the PTFE cover and the Heat-On block can be as much as 100°C reducing the temperature of exposed surfaces by as much as 50%.

Improved efficiency

The insulating properties of the PTFE Safety Covers mean that up to 15% less energy is required to maintain temperatures for extended periods.
