Lambda (written λ, in lowercase) is a non-SI unit of volume equal to 10 −9 m 3, 1 cubic millimetre (mm 3) or 1 microlitre (μL).Introduced by the BIPM in 1880, [1] the lambda has been used in chemistry [2] and in law for measuring volume, but its use is not recommended.
Therefore, to ensure that a sample will yield CFU in this range requires dilution of the sample and plating of several dilutions. Typically, ten-fold dilutions are used, and the dilution series is plated in replicates of 2 or 3 over the chosen range of dilutions. Often 100 μL are plated but also larger amounts up to 1 mL are used.
Viral load is reported as copies of HIV RNA in a millilitre (mL) of blood. Changes in viral load are usually reported as a log change (in powers of 10). For example, a three log increase in viral load (3 log10) is an increase of 10 3 or 1,000 times the previously reported level, while a drop from 500,000 to 500 copies would be a three-log-drop ...
Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important variable that must be monitored.
Air displacement micropipettes are a type of adjustable micropipette that deliver a measured volume of liquid; depending on size, it could be between about 0.1 μL to 1,000 μL (1 mL). These pipettes require disposable tips that come in contact with the fluid. These pipettes operate by piston-driven air displacement. A vacuum is generated by ...

The dilution of insulin is such that 1 mL of insulin fluid has 100 standard "units" of insulin. [6] Since insulin vials are typically 10 mL, each vial has 1000 units.
The Raven 1000 UL is an American aircraft engine, that was designed and produced by Raven Redrives of El Prado, New Mexico for use in ultralight and homebuilt aircraft. [ 1 ] The company seems to have gone out of business in 2017 and production ended.
