Hotplates and Stirrers
Hotplates and hotplate stirrers are benchtop laboratory tools that are used to heat evenly and mix various types of liquids and solutions. Conventional hotplates are used for heating only, while combination hotplate stirrers are able to simultaneously heat and mix. Infrared hotplates are an energy-efficient alternative to conventional and combination hotplate stirrers.
Available in various formats, our hotplates and hotplate stirrers offer the latest technology in single or multiple platforms and in both analogue and digital formats. A variety of capacities are available, ranging from a few milliliters up to 10 L or more, with a choice of top plate materials to fit application requirements.
The combination of operational simplicity, reliable performance, and advanced safety makes choosing the perfect hotplate or hotplate stirrer easy.
Hotplates and Hotplate Stirrer Features
Conventional hotplates or specialty hotplates offer ceramic, aluminum, or stainless-steel top plate surfaces, with multiple plate shapes and dimensions.
Combination stirring hotplates range from the most basic stirring design to explosion-proof models for hazardous lab applications, while providing precise control and repeatability to meet a variety of application needs.

Magnetic stirring Hotplate Price in Bangladesh
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). And. So so. And. So so. And. So so
Much of the current magnetic stirrers rotate the magnets by means of an electric motor. This type of equipment is one of the simplest to prepare mixtures. 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. However, the limited size of the stir bars enables using this system only for volumes less than 4 L.

A stir bar consists of a magnetic bar used to agitate a liquid mixture or solution (Figure 6.6). Because the glass does not affect a magnetic field significantly, and most of the chemical reactions are performed in glass vials or beakers, stirring bars function adequately in glassware commonly used in laboratories. Typically, stirring bars are coated with Teflon® or glass, so they are chemically inert and do not contaminate or react with the system in which they are immersed. Their shape may vary to increase efficiency during stirring. Their size varies from a few millimeters to a few centimeters.
The magnetic or mechanical stirring by itself is not effective for dispersing nanoparticles. And. So so. And. So so. And. So so
