blotting
A blot, in molecular biology and genetics, is a method of transferring proteins, DNA or RNA onto a carrier (for example, a nitrocellulose, polyvinylidene fluoride or nylon membrane). In many instances, this is done after a gel electrophoresis, t ...

Cell culture or tissue culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. The term "tissue culture" was coined by American pathologist Montrose Thomas Burrows. This te ...
and gentle mixing.
Two-dimensional rockers use a platform that moves in a seesaw motion to create waves in liquid laboratory samples. Three-dimensional rockers move a platform in a three-dimensional gyratory motion to create a gentle swirling of samples.
Typical features of laboratory rockers include variable speeds, and tilt angles. Rockers are often designed to accept stackable platforms or may be outfitted with multiple tiers to increase capacity without increasing the footprint.
