Top 3 Things You May Not Know About Shakers & Stirrers

1. The first hot plate stirrer was patented in 1917 by Richard Stringham of Utah and consisted of stationary electromagnets built into a hotplate base. When a reaction vessel such as a flask or beaker was positioned on the stirrer, a bar magnet placed in the solution rotated as a result of the magnetic field created by the electromagnets.

2. A significant problem of early twentieth century research was the risk of fire from the necessity of heating solutions using a naked flame. This problem was resolved in the 1930s by husband and wife team Glen and Ruth Morey who invented the heating mantle, a reliable and non-flammable heating device with electric resistance wires woven into a fiberglass cloth sheath.

3. The bar magnet used with the first magnetic stirrers was gradually found to be less than ideal, particularly because the iron in the magnet could react with chemicals in the solution and change the course of a reaction. To address this problem, two inventors working independently in the 1940s devised the coated magnetic stirrer bar, which was chemically inert and took no part in the ongoing reaction.
