Tube & Cuvette Functions/Applications
Storage and analysis of samples in solution are made possible by the wide range of tubes available on the biotech market, while cuvettes are necessary for spectroscopic studies measuring concentration.
Centrifuge & Microcentrifuge Tubes
Centrifuge and microcentrifuge tubes are used for the preparation and storage of reaction mixtures and samples respectively. Their main function is the separation of solutions according to size and density; which can be applied to nucleic acid extraction and cell cultivation (i.e. when refreshing cell media). Both sizes can be provided as sterile and tend to be autoclavable. Regarding size, centrifuge tubes handle larger volumes, usually in the milliliter (ml) scale, while microcentrifuge tubes deal with much smaller quantities, on the microliter scale (µl).
Cuvettes, also known as spectrophotometer cells, may be rectangular or cylindrical, have a capacity in the milliliter range and are used for electroporation or spectroscopic testing of liquids.
