Condensers and graduated receivers for determination of water content by the Dean and Stark method of distillation with an immiscible liquid. Five sizes of ordinary type of receiver for light liquids (e.g. petroleum spirit, toluole), two sizes of a modified type for heavier liquids (e.g. trichloroethylene, perchlorethylene). Some sizes are provided with stopcocks and alternative connections (ground glass joints or corks) to the distillation vessel; the condenser connection is standardized as a B19 joint.Cross References:BS 76BS 209BS 241BS 261BS 331BS 390BS 434BS 517BS 521BS 523BS 524BS 544BS 572BS 598 BS 618BS 628-32 and 650-56BS 684BS 735BS 742BS 929BS 1011BS 1016BS 1017BS 1033BS 1067BS 1070BS 1177BS 1375BS 1450BS 1469BS 1673:Part 2BS 1715BS 1737
