Cole-Parmer Lab Companion M5-53M Multi-position Stirrer, 15 position 100-240V
These multiposition stirrers have four user-friendly operating modes that allow the selection of specific rows and columns, individual stirring of each position, or simultaneous stirring of all positions. Units are easy to read with digital VFD control monitors and LED operating lamps. The advanced microprocessor PID controls accurately control stirring speed. Top plates are stainless steel for excellent chemical resistance. Brushless DC motors are quiet and durable. Gradual start-up, built in thermal shutdown, and current limit protection device provide user safety.
Across International 350C 2000RPM 2-Gallon PID Magnetic Stirrer w/ 11" Heated Plate
A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called "flea") immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. Since glass does not affect a magnetic field appreciably (it is transparent to magnetism), and most chemical reactions take place in glass vessels (i.e. see beaker (glassware) or laboratory flasks), magnetic stir bars work well in glass vessels. On the other hand, the limited size of the bar means that magnetic stirrers can only be used for relatively small experiments. They also have difficulty dealing with viscous liquids or thick suspensions. For larger volumes or more viscous liquids, some sort of mechanical stirring is typically needed.
