The exact features of the different concentrators can vary. They will generally include a vacuum, protein concentrator, centrifugal concentrator, evaporative, and heated concentrator. They also include cold traps and vacuum pumps. These will help to stop vapors from getting into the vacuum pump. Of course, they will also have safety features, such as cover locks. It is possible to have the concentrator equipped with built-in pumps, glass traps, and infrared lids that make it possible to concentrate, or evaporate, up to 100 DNA samples at one time. This is highly beneficial for busy, modern labs.
How concentrators work
Often, those working in a laboratory setting will need to remove the organic components from their samples, and one of the best ways to do this is with a concentrator. Most of the machines will offer the ability to work with multiple samples at the same time – up to a hundred or more. They have variable settings for drying, and many will have both a manual and auto run option. The systems work by lowering the pressure in the centrifuge chamber. By dropping the pressure, it also drops the boiling point for the solvent. This makes the boiling and evaporating process much faster, and it can do this without raising the temperature so much that it becomes damaging to the samples.
A concentrator is a type of laboratory device that makes use of centrifugal force, along with a vacuum and heat as a means to remove water and organic solvents from samples. These samples could be in tubes, vials, or microplates, and they are generally very small. The small size allows to machine to work with a large number of samples simultaneously.
