Synthesis and Evaporatio?n In Pear-Shaped Flasks

Asynt has developed a version of DrySyn heating block purpose designed to allow scientists to perform safe, productive heating and stirring experiments with pear-shaped flasks commonly used with rotary evaporators.


Pear-shaped flasks are popular with organic chemists as concentrated samples can be removed much more easily than from a round bottom flask. Pear-shaped flasks are used for evaporating solutions to dryness post synthesis using a rotary evaporator, the 'rounded V' shape of the flasks enables solid materials to be scraped out more efficiently than from a round bottomed flask. Martyn Fordham, Managing Director of Asynt commented: “By designing a version of the DrySyn to accept these flasks, chemists can now eliminate the need for sample transfers between reaction flask and an evaporator (pear-shaped) flask, allowing the same flask to be used for both Synthesis and Evaporation.”


Made of chemically resistant, anodized aluminium, the DrySyn range of heating blocks for pear-shaped flasks (100 mL, 250 mL, 500 mL, 1000 mL) offer excellent heating performance to more than 300 ºC and can heat a reaction flask 25% faster than an oil bath. Providing excellent heating and stirring performance but without the inherent risks and mess of an oil bath, DrySyn heating blocks help laboratory scientists create a safer, cleaner and more efficient working environment. DrySyn heating blocks also offer a flexible, safe alternative to using heating mantles.
