It was invented by Lyman C. Craig and Otto W. Post. [1] A Craig tube consists of two parts. The first is a stout-walled test tube with a working volume of about 1-5 ml (say, 7-8 cm in length and 1-1.5 cm in diameter). There is a constriction towards the open end of the tube.
In 1950, Craig invented the rotary evaporator which is a necessary equipment in most chemical labs. [5] [6] He also invented the Craig tube, an apparatus used in small-scale chemistry, in particular for recrystallization. [7] He received recognition from his peers and several honors for his scientific accomplishments.
The Cragie tube or Craigie tube is a method used in microbiology [1] [2] for determining bacterial motility. Technique.

Recrystallization is a method used to purify chemicals by dissolving a mixture of a compound and its impurities, in an appropriate solvent, prior to heating the solution. [1] Following the dissolution of crude product, the mixture will passively cool, yielding a crystallized compound and its impurities as separate entities.
In materials science, recrystallization is a process by which deformed grains are replaced by a new set of defect-free grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the strength and hardness of a material and a simultaneous increase in the ...
