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.
These devices allow to mix gently and resuspend with force, cells and liquid components in tubes, with a high degree of efficiency and precision at the moment of mixing, compared to other equipment with the same characteristics; Therefore, it is considered a very useful tool since it is used to mix substances and save time in stirring liquids.
How is a tube shaker made?
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 touched), the movement is transmitted to the liquid inside and a vortex is created.
They 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, 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 set to run continuously or to run only when downward pressure is applied to the rubber part.
How do you use a tube shaker?
A tube shaker is designed to be used with one tube or multiple tubes as needed. It has two modes of operation, continuous stirring and by contact.
To begin using this device, you must place the shaker on a stable, level surface near a grounded outlet. It is recommended that the surface be clean and dust-free to ensure that the feet of the equipment are firmly attached to the surface. Leave enough free space on all sides of the unit for proper ventilation. With the switch in the OFF position, connect the power cord to a grounded electrical outlet.
