Mixing Up The Microplate In The Lab

Mixing the contents of microplates can be seemingly tricky, particularly when done by hand. Powder mixing before inoculation or delivery of liquids may also be formidable if done manually. The use of a good microplate shaker is a decent step forward to correct mixing of powders, compounds and liquids in the laboratory microplate system.

There are many sorts of mixing products available to the science laboratory. Orbital shakers revolve in a circle, which creates a more mild swirling motion of the liquids in the microplate wells. This is wonderful to keep fluids in an incubating microplate from forming a “skin”, or to keep it from gelling. It's also for the gentle blending of delicate proteins or enzymes.

The reciprocating shaker systems can move the liquids in a backward and forward motion, which is good mixing for a number of applications using different sizes of microplates including 96 well plate products. The liquids in the wells are carefully swished about, which should give general mixing over a period. A membrane-covered microplate could be mixed using this method, as the sloshing liquids have no possibility of spilling out.

The “figure-eight” motion shakers are excellent for cell biology studies, as they create a better oxygenation of the liquids the living cells are suspended in. Cell cultures benefit from this type of shaking microplate, and each well achieves a similar mixing quality. This type if shaker can be adjusted for different speeds, which is useful to the lab, as it provides more diversity in what can be mixed in this technique.

Vortex shakers are used so usually in labs, they can be discovered in nearly all kinds of laboratories. These shakers make a vortex within the liquids to be mixed, which is a slightly robust technique for mixing. They may also be used to break down components with the fluid, for elimination later on. A touch-sensitive base is standard kit, so the tube can be set on the mixing cup, pushed down lightly, and the vortex action can then take over.
