Abstract : A new type of weighing flask is described suitable for the preparation of quantitative solutions in volatile solvents. It allows the direct transfer of the solution to an infrared absorption cell without the intermediary use of a pipette, syringe or other transfer device. It also permits the recovery of the quantitative solution after the measurement. Two modifications of the flask are illustrated, one of which will deal with volatile solutes as well as volatile solvents. The flask may also be used for the preparation and manipulation of other types of quantitative solutions where it is desired to minimize exposure to the atmosphere. These could include radioactive solutions, solutions in hygroscopic solvents such as sulfuric acid or deuterium oxide, or sterile aqueous solutions. (Author)
