Eight flasks (sizes, material, construction, dimensions and inscriptions); three Crow receivers (sizes, material, construction, dimensions, graduations); three types of draught screen; three types of condenser; auxiliary equipment (heaters, thermometer, flask support boards). Guidance on assembly.

This British Standard specifies requirements for a range of components for the following apparatus used in the determination of the distillation characteristics of materials:

  1. distillation flasks of sizes between 50 mL and 750 mL;
  2. three Crow receivers of two classes of accuracy;
  3. glass condensers of air-cooled and fluid-cooled designs;
  4. metal condensers and cooling bath;
  5. draught screens of three types;
  6. heaters using either gas or electricity.

NOTE 1 It is recommended that, unless otherwise specified in the relevant method of test, one of the types of thermometers listed in BS 593, with an immersion length of 100 mm, is used.

NOTE 2 Guidance on how the apparatus may be assembled is given in Appendix A.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
