Laboratory stirrers | Choosing the Right Laboratory Stirrer
Stirrers, or shakers, are widely used in laboratories to mix and agitate samples before analysis. There are various types of laboratory stirrers (magnetic, vortex, roller, etc.). Although they all allow liquid solutions to be mixed, each one meets different needs, so choosing the right type of stirrer is important. To do this, the properties of the sample must be taken into account (viscosity, presence of living cells, etc.), which will largely dictate the...

How to choose this product
laboratory-stirrer

An agitator mixes liquids to ensure homogeneity. It also speeds chemical reactions among the mixture's constituents.

Applications

These devices are found in laboratories and industrial settings, including biological, chemical and petrochemical facilities, in metallurgy, pharmaceuticals, agribusiness, water treatment plants, paper and perfume manufacturing. They mix paints and varnishes, fruit juice, wine and milk products, among others.

Technologies

In magnetic laboratory models, the container holding the liquid sits on a plate. A rotating magnetic field beneath it spins a small bar magnet placed in the liquid. The plate also may be a heating element. Other types include shakers, vibrators and mechanical agitators with a plunger.

Industrial versions are mechanical, driven by an electric motor with electronic variable speed control. They include impeller, propeller, anchor or butterfly models. Some are double-action, with an element that scrapes the sides of the vessel. Magnetic drive ensures that the container remains watertight. These machines have a horizontal or vertical axis and create radial or axial motion in the liquid.

How to choose

Choice will depend on speed range (in rpm), the type of motion imparted and the operational conditions (pressure, liquid viscosity, corrosion factors).
