"Short path" refers to the short distance that the vapors of the distillate need to travel, which helps reduce loss and speed up collection of the distillate.This type of distillation is generally performed under vacuum to prevent the compound from charring due to atmospheric oxygen, as well as to allow the distillation to proceed at a lower temperature.
Air-free techniques refer to a range of manipulations in the chemistry laboratory for the handling of compounds that are air-sensitive. These techniques prevent the compounds from reacting with components of air , usually water and oxygen ; less commonly carbon dioxide and nitrogen .
The process thus in its essence is similar to distillation, however the material which is condensed on the cooler surface then has to be removed mechanically, thus requiring different laboratory equipment. Bioleaching is the extraction of metals from their ores through the use of living organisms. Separation process. From Crystallization
Laboratory methods and techniques, as used in fields like biology, biochemistry, biophysics, chemistry, molecular biology, etc. Subcategories. This category has the ...
Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.
This procedure was repeated several times, to ensure no moisture was left on the glassware. Using a Teclu burner instead of a heat gun will ensure that you have obtained the lowest possible moisture levels in glass laboratory equipment and this should be sufficient for the moisture sensitive substances to not react when added into the glassware.
Maybe it was nerves for her first World Cup race back in nearly six years. Whatever it was, Lindsey Vonn took just a handful of gates this weekend to recover from a poor start and rediscover her ...
Septa seal the two conical flasks. A cannula is used to transfer THF from the flask on the right to the flask on the left.. Cannula transfer or cannulation is a set of air-free techniques used with a Schlenk line, in transferring liquid or solution samples between reaction vessels via cannulae, avoiding atmospheric contamination.
