Laboratory Shakers

Laboratory shakers, also known as mixers, are laboratory products used in the chemistry and biology industries to mix liquids and prepare solutions and suspensions. These equipments create a movement between liquids or between liquids and solids in order to achieve mixing, suspension, dispersion, homogenization, heat transfer, etc. At present, stirring systems (agitators) are used in all laboratories, be they chemistry, biology, among others. .

The different models of shakers, rockers and rotators are designed to house tubes, microplates, cell culture flasks, flasks or similar containers. Mini stirrers are small and space saving; Other shakers, rockers, and rotators are the size of a standard table, although some are freestanding and stackable.

Laboratory shakers: porcelain or glass dishes

The laboratory shaker are electromechanical devices that are commonly used in specialized chemistry and / or biology laboratories to homogeneously mix solutions and suspensions for tests and trials.

Average stirrers are made up of a plate, which is driven by an electric motor. The sample to be mixed is introduced into a container, which can be a beaker, tube or flask, which is positioned on a vibrating surface. These devices can be used in the production of chemicals, cosmetics, food, coatings among others. In research, development, clinical research and education laboratories, the shaker is essential equipment, easily adapting to small spaces and also easy to move from one location to another.

Laboratory shakers: different types and applications

Laboratory stirrers are electromechanical devices that are commonly used in laboratories to homogeneously mix solutions and suspensions. These are generally made up of a plate, which moves propelled by an electric motor. The sample to be mixed is introduced into a container, which can be a beaker, tube or flask, which is positioned on a vibrating surface.

These equipments are used in the elaboration of chemical products, cosmetics, food, coatings, among others. They are equipment that easily adapt to small spaces and are easy to move from one place to another.

They are used to shake test tubes or the like in laboratories. This type of mixer consists of an electric motor with the transmission shaft oriented vertically and attached to a piece of rubber or rubber in the shape of a cup, slightly eccentric, where the tube to be stirred rests. Also, they have suction cup feet at their base to prevent displacement.

Magnetic Multi-Position Thermostatic Stirrer (Hot Plates) YR02948

Magnetic stirrers are often used in chemistry and biology. They are preferred over motorized agitator gear driven ones because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet). Due to its small size, a stir bar is more easily cleaned and sterilized than other stirring devices.

They do not require lubricants that can contaminate the reaction vessel and product. They can be used inside hermetically sealed containers or systems, without the need for complicated rotary seals. Magnetic stirrers can also include a hot plate or some other means to heat the liquid.

Very compact and easy to operate
Temperature and speed digital display, heating temperature: Rt-380 degrees and mixing speed: 100-1800 RPM

How is a tube shaker made?

The agitators are composed of multiple procedures and here we will mention the most relevant ones:

A tube shaker is generally composed of an electric motor with the shaft connected to a cup-shaped piece of rubber mounted slightly off-center, or to a movable rack.

The rubber part motor oscillates rapidly in a circular motion. When a test tube is pressed into the rubber cup (or its edge is touched), the movement is transmitted to the liquid

They have a different speed setting that can be adjusted for continuous use. As the engine is running, the rubber part oscillates

When a test tube or other suitable container is pressed into the rubber cup, the movement is transmitted into the liquid and a vortex is created, thus producing effective mixing of the solution.

Most vortex mixers are designed in 2- or 4-plate formats, have variable speed settings between 100 and 3,200 rpm, and can be adjusted to operate.

Types of Agitators most used in the laboratory:

Vortex stirrers

They are used to shake test tubes or the like in laboratories. This type of mixer consists of an electric motor with the transmission shaft oriented vertically and attached to a piece of rubber or rubber in the shape of a cup, slightly eccentric, where the tube to be stirred rests. Also, they have suction cup feet at their base to prevent displacement. The stirring speed can be regulated.

Orbital shakers

The orbital shaker is a piece of equipment used in laboratories, clinics and others; for mixing, homogenizing and / or preparing combinations of substances. There is a great variety of presentations of these teams and they depend mostly on their size and if their speed is fixed or adjustable. This equipment consists of a time control which can be adjusted according to the need

Magnetic stirrers

They are the most used in laboratories and at the same time the safest, because they use stirring bars that can be disinfected. This type of mixer is composed of a plate with a magnet or a series of electro magnets, arranged in a circular shape at the bottom, which create a rotating magnetic field that acts by means of an electric motor controlled by an electronic device.

Tube shakers in a laboratory

The agitators for tubes in a laboratory are equipment used in laboratories to mix tubes with liquid, and thus obtain homogeneous suspensions. They consist of an electric motor with a vertically oriented drive shaft attached to a slightly mounted rubber part, or to an arm attached to a movable rack.
