Such a vessel makes it possible to store and transport materials at very low temperatures, e.g. liquid nitrogen which boils at 77K (-195°C).
A flask used in the Kjeldahl method for the determination of nitrogen.
A flask with a long cylindrical neck on which is engraved a mark corresponding to a precise volume. Graduated flasks are used to prepare solutions for analytical work, e.g. titrations, and to carry out accurate dilutions of stock solutions.
A flask used for semi-micro distillation.
A flask used in the Kjeldahl method for the determination of nitrogen.
A flask or an erlen used to collect liquids durind a distillation, an extraction or a digestion procedure.
