Two new configurations for the successful DrySyn system of laboratory heating blocks add even more flexibility for the pharmaceutical or process chemist and provide economical synthetic chemistry solutions for the teaching laboratory. The DrySyn Multi M and Multi S each provide a compact reaction station for up to three standard round bottomed flasks, with maximum volumes of 250ml and 500ml respectively. Any flask size down to 5ml can be used in both models with the appropriate inserts. Both models can also accommodate up to 12 vials or tubes.

Used with a standard hotplate stirrer, these blocks conveniently replace dangerous oil baths in the chemistry laboratory, and can heat a reaction flask 25% faster than an oil bath. DrySyn heating blocks offer excellent heating performance up to 300ºC, a small footprint and exceptional reaction visibility, and are fully compatible with magnetic stirring. The ingenious 3-way Multi Clamps make it quick and easy to secure flasks in place. An additional economy is that existing DrySyn Multi users can use their DrySyn inserts in the Multi M and Multi S - they are directly compatible. DrySyn blocks are made of chemically resistant, 100% recyclable aluminium.

DrySyn heating blocks also offer an excellent alternative to heating mantles, which can not only be a potential fire hazard with flammable solvents but, because a different unit must be used for each flask size, are considerably more expensive. DrySyn's combination of safety and economy has made the concept particularly popular in teaching laboratories, where a single unit can provide heating facilities for several students.
