A vortex is a device used in laboratories to mix small vials of liquid. It consists of an electric motor with a vertically oriented drive shaft attached to a slightly mounted recessed rubber part.
It is an ideal instrument for gently mixing and forceful resuspension of cells and components of chemical and biological liquids in tubes using an eccentric mechanism.
This equipment is very important in the laboratory, like other equipment, since it helps and allows the development of some research. It is considered a very useful tool for mixing substances. It also saves time on stirring liquids.
A vortex mixer offers a high degree of efficiency and precision when mixing, compared to other equipment with the same characteristics.
Structure of a vortex mixer
A vortex mixer is made up of an electric motor with the drive shaft oriented vertically and connected to a cup-shaped piece of rubber mounted slightly off-center. The rubber part motor oscillates rapidly in a circular motion. When a test tube or other suitable container is pressed into the rubber cup (or its edge touched), the movement is transmitted to the liquid inside and a vortex is created. Most vortex mixers have a variable speed setting and can be set to run continuously, or to run only when downward pressure is applied to the rubber part.
They usually have a different speed setting that can be adjusted for continuous use. As the engine is running, the rubber piece swings rapidly in a circular motion. 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.
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 run continuously or to run only when downward pressure is applied to the rubber part.
How do you use a vortex mixer?
A vortex mixer is designed to be used with one tube or even multiple tubes as required. It has two working modes, continuous stirring and by contact.
This equipment is ideal for intermittent shaking work using tubes, erlenmeyer flasks, beakers, flasks, etc. being able to shake several tubes at the same time. It is not at all limited to the maximum size of the tube or container to be used, much depends on the technique, the shape of the container, the viscosity of the content and the amount of the liquid.
To begin using this equipment, place the shaker on a stable, level surface near a grounded electrical outlet. The surface must be clean and dust-free to ensure that the feet are firmly attached to the surface. Leave enough free space on all sides of the unit for adequate ventilation. With the switch in the OFF position, connect the power cord to a grounded electrical outlet.
