The Easy Way To Make A Stir In The Lab Environment

Magnetic laboratory stirrer instruments have been in existence for many years, their easy yet ingenious design aiding in the the emulsification of solids into liquids and also the mixing of chemicals. There are numerous kinds of mixing instruments in the laboratory which fall into the categories of warmed and cooled stirring, laboratory jaw crusher devices, batch mixing, magnetic products and fast mixing applications.

The development of these flexible machines is comprised of a motor fixed to a shaft, attached to a bar magnet. This rests underneath a plate where the mixing container is located. A capsule, or “flea”, composed of a plastic coated bar magnet, is situated in the media to be mixed and the unit is turned on. This spins the larger bar magnet under the base, therefore spinning the flea in the media, causing a mixing action called a vortex.

To advance even further with stirring chemicals for reaction, the magnetic stirrer features a heated or cooled platform. This is handy to cause or diminish catalytic reactions within the mixable media. The heating part can be changed for a wide temperature range, giving great control over experimental or testing reactions.

The cooling mechanism for the laboratory hotplates is a thermoelectric device called a Peltier thermoelectric plate. Using electricity, the principle is that the plate draws heat away from a surface, therefore cooling it. This system is useful as it can bring freezing temperatures to the mixing process. It’s also handy for preserving reagents before use, and keeping the reagents well mixed.

These warmed and cooled magnetic stirrers come in a variety of sizes to handle nearly any mixing or stirring requirement. There are far more powerful stirrers that may compensate for the viscosity of a liquid, keeping the materials mixed up well.

The importance of these versatile devices is paramount to R&D. They have a massive niche in chemistry analysis and chemical development. Without correct stirring, most chemical reactions would lack the capability to occur, and without cooling or heating, the reactions would be either nonexistent or too slow for practical purposes.
