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.

2022年11月25日 · A magnetic stirrer is a laboratory device that employs a rotating magnetic field generated by a rotating magnet or stationary electromagnet to cause a stirrer bar immersed within a liquid to spin and thus quickly stir or mix the solution.

2023年10月26日 · A magnetic stirrer, also known as a magnetic stir plate or magnetic mixer, uses a rotating magnetic field to cause a stir bar immersed in a liquid to spin rapidly, thus stirring it. The core component of a magnetic stirrer is a spinning magnet or a set of stationary electromagnets, creating a rotating magnetic field.

2024年2月12日 · What is a magnetic stirrer? A laboratory tool extensively employed is the magnetic stirrer, alternatively termed a magnetic mixer, which has significantly transformed the stirring and mixing of solutions in scientific settings.

2024年5月14日 · A magnetic stirrer is a laboratory instrument designed to mix liquids using a rotating magnetic field. This field causes a magnetic stirring bar, submerged in the liquid, to spin rapidly and mix the contents.

The magnetic stirrer is an essential piece of laboratory equipment used for stirring or mixing in laboratory experiments by creating a rotating magnetic field. The rotating magnetic field is created with the help of a rotating magnet (i.e., stir bar) and a stationary magnet.

Our multi-point magnetic stirrers are designed with 4, 6, 15 or 60 stirring points with good speed control to meet various needs in all labs. They are applicable in various operating conditions such as daily lab use, or in water baths and CO 2 incubators.

Benchtop stirrer units that employ a rotating magnetic field to spin magnetic rods or stir bars to aid in laboratory stirring applications. Products are available in various sizes and stirring speed capabilities and may have multiple stirring positions. …

2024年10月1日 · Magnetic stirrers are quieter and more efficient than mechanical stirrers. They require little maintenance. Magnetic stirrers are suitable for aqueous solutions and media with a low viscosity of up to 100 mPa. The best speed is usually between 400 and 800 rpm.

2024年3月19日 · A magnetic stirrer, also known as a magnetic mixer, is a widely used laboratory device that revolutionized the process of stirring and mixing solutions.

2025年1月21日 · What Exactly Is a Magnetic Stirrer? its a simple & durable device designed to mix liquids. At its main work is by using a magnetic field to spin a small bar inside the liquid, called a stirrer bar. This setup ensures that the liquid gets mixed evenly without much hassle.

2021年2月25日 · What is a magnetic stirrer? Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples, and some are coupled with stirring hot plate. The movement of this stir bar mixes the samples thoroughly with rapid movement and agitation.

Magnetic stirrers are silent and provide the possibility of stirring closed systems without the need for isolation, as in the case with mechanical agitators. Because of their size, stir bars can be cleaned and sterilized more easily than other devices such as stirring rods.

2022年11月29日 · A magnetic stirrer is a device that is designed for stirring a liquid using a rotating magnetic field. It is a piece of lab equipment that is widely used for the preparation of solutions, especially for low viscosity fluid mixing.

What is the Magnetic Stirrer ? A magnetic stirrer or magnetic mixer is a laboratory device that uses a rotating magnetic field to make a stirring rod immersed in a liquid rotate very quickly, stirring it. The rotating field can be created by a rotating magnet or a set of stationary electromagnets, placed under the vessel with the liquid.

Benchmark Scientific Hotplates and Stirrers provide reliable performance and safe operation for everyday laboratory use. Our space efficient 7 x 7inch hotplate/stirrer series features a durable, chemical resistant white ceramic top plate and advanced microprocessor controls.

2023年9月1日 · Magnetic stirrers are widely used in laboratories for mixing, stirring, and homogenizing liquids. When selecting a magnetic stirrer, consider the following factors: Stirring Capacity: Choose a model with an appropriate stirring …

Magnetic declination (variation) calculator based on the IGRF magnetic field model. Estimates magnetic delination world-wide from 1900 - present.

Enter a street address, street name, or street intersection. For best results, include as much location information as possible with the street address in your search, such as city, state, zip code.

Magnetic declination (sometimes called magnetic variation) is the angle between magnetic north and true north. Declination is positive when this angle is east of true north and negative when it is west. Magnetic declination changes over time, and with location.
