Magnetic Stirrer - an overview ScienceDirect Topics

A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).

Influence of tannin and iron ions on the water resistance ...

Mar 14, 2022 The influence of the combination of oak tannin with iron chloride on the properties of clay materials in terms of rheological behavior, compressive strength, and water resistance was studied. We show that adding iron chloride can annihilate the deflocculation action of tannin by a complexation reaction between iron ions and tannin.
