Synthesis & Evaporation In Pear Shaped Flasks

Product News Thursday, January 30, 2014: EngNet - Engineering Network

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 (100mL, 250mL, 500mL, 1000mL) offer excellent heating performance to over 300ºC and can heat a reaction flask 25 per cent 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.
