Product Description

Hotplate Magnetic Stirrer

The hotplate stirrer (or hot plate stirrer or hot plate magnetic stirrer) is used for mixing and heating aqueous solutions for a great variety of chemical reactions such as synthesis. VELP hotplate stirrers are available in various models and combinations in both analog and digital configurations.

A hotplate magnetic stirrer works by using a rotating magnetic field to stir a liquid in a container. The hot plate heats the liquid to the desired temperature, while the stirrer ensures that the temperature is even throughout the solution.


Safety:

Safety: Wear appropriate personal protective equipment (PPE), including lab coats, safety goggles, and gloves.
Ventilation: Work in a well-ventilated area or inside a fume hood when dealing with hazardous chemicals.
Emergency shutdown: Familiarize yourself with the emergency shutdown procedures for both the hotplate and the stirrer.
Don’t leave it unattended: Don’t let the vessel boil dry.
Don’t touch it: Don’t touch the heating surface, or other parts of the unit except the control knobs.
Avoid spills: Avoid spilling liquid on the base as it will damage the unit.
Don’t use near flammable vapors: Avoid using the unit near flammable vapors or to heat flammable liquid.


Applications

A hotplate magnetic stirrer is a laboratory tool used to mix and heat liquids for a variety of scientific applications, including:
