Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45

Specifications. Description. 16mm Hach vials for vials for Chemical Oxygen Demand ( COD ) determination. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport.

The CMUV Electromantles deliver the benefits of the CMU Electromantle, but do so for very large 60 funnels, as well as pear-shaped and round bottom flasks. This is achieved through a "V-shaped" design for the heating mantle, with funnels being accommodated through a bottom

of chemical interaction with the contents. . . . However, the limits of acceptability in these various respects depend, at least in part, on climatic variables. Recommendations in The international pharmaco-poeia can only be advisory; precise quantitative standards 2
