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.
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.
The Cragie tube or Craigie tube is a method used in microbiology [1] [2] for determining bacterial motility. Technique.
In a now-viral TikTok, Ashley Wanichko shares her cruise experience aboard Carnival's Mardi Gras when she shared a tiny room with her boyfriend and sons
Recrystallization is prevented or significantly slowed by a dispersion of small, closely spaced particles due to Zener pinning on both low- and high-angle grain boundaries. This pressure directly opposes the driving force arising from the dislocation density and will influence both the nucleation and growth kinetics.
