Which Magnetic Stirrer Pdf

A hot plate is a portable self-contained tabletop small appliance cooktop that features one or more electric heating elements or gas burners.A hot plate can be used as a stand-alone appliance, but is often used as a substitute for one of the burners from an oven range or a kitchen stove.Hot plates are often used for food preparation, generally in locations where a full kitchen …

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).

A rotating magnetic field is the resultant magnetic field produced by a system of coils symmetrically placed and supplied with polyphase currents. A rotating magnetic field can be produced by a poly-phase (two or more phases) current or by a single phase current provided that, in the latter case, two field windings are supplied and are so designed that the two …

Add a magnetic stirring bar to the beaker and place the flask on a microscale magnetic stirrer. At room temperature, with stirring, carefully add 6M NaOH solution dropwise until the solution is basic to red litmus paper. Use a capillary tube to remove sample for pH testing. A

Since then, the overhead stirrer series has evolved enormously and, with its state-of-the-art engine technology, is the basis of an optimal stirring system. From the compact Hei-TORQUE Core with 40 Ncm torque to the intelligent Hei-TORQUE Ultimate models (available in 100, 200 and 400 Ncm), all Heidolph overhead stirrers are very easy to operate.

The stirrer bar is important to avoid “bumping” of hot liquid Set up and use apparatus in a fumehood The sample liquid (approx. 0.5 mL) is introduced into a 150mm diameter test tube using a Pasteur pipette and a small magnetic stirring bar is …
