A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or 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.
A hot plate or hotplate is a heated flat surface on a stove or electric cooker on which food may be cooked. [3] It comprises a heated top which is flat and usually circular, and may be made of metal, ceramic, or heat-resistant glass, with resistive wire forming a heating element fitted underneath and a thermostat to control the temperature.
The tube is wider and its top is covered with a plate mesh, which separates the flame into an array of smaller flames with a common external envelope, ensures uniform heating, also preventing flashback to the bottom of the tube which is a risk at high air-to-fuel ratios and limits the maximal rate of air intake in a Bunsen burner.
Although the magnetic stirrer has lately come to replace the shaker, it is still the preferred choice of equipment when dealing with large volume substances, when simultaneous agitation is required or when stirring bar could destroy delicate content like living cells. [1]
Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
Circulating water baths (also called stirrers [10]) are ideal for applications when temperature uniformity and consistency are critical, such as enzymatic and serologic experiments. Water is thoroughly circulated throughout the bath resulting in a more uniform temperature.
#3 The Tomorotec's Expandable Shelf Organizer Keeps Your Plates In Place. Review: "These were perfect for what I needed. They are sturdy, stand firm, and can hold the weight of glass. They don't ...
The sample is then heated, either by a heating block or an oil bath, and as the temperature increases, the sample is observed to determine when the phase change from solid to liquid occurs. The operator of the apparatus records the temperature range starting with the initial phase-change temperature and ending with the completed phase-change ...
