Pear Shaped Flasks
Pear-shaped flasks are mainly used for evaporating solutions, as they are much more suited for this task compared to round bottom flasks. They are an ideal choice for obtaining concentrated samples post rotary evaporation. The rounded ‘V’ shape of the flasks makes it easier to efficiently obtain the solid residue from the bottom of the flasks. These flasks are generally used on the smaller scale and are available in a range of sizes. These flasks are primarily used to boil or evaporate liquids. The capacity of the flask is usually inscribed on the body. In certain models, the neck ends in a standard ground joint or a rimmed opening. The ground joint comes in handy when the flask needs to be attached to other equipment like a distillation unit or a rotary evaporator. Some of the models may have tubular necks ending with standardized ground glass joints (female) which fit in any similar sized male joints. A range of such flasks with different capacities can be purchased at BioMall website.
