Generally, low speed centrifuges do not exceed 4000 rpm in rotational speed and have a maximum capacity of 2-4l. They are usually handled in laboratories, for primary separation and extraction of large amounts of biological macromolecules and sediments. They have mechanisms made with aluminum fusion, flat type and angle type.

Centrifugal tubes are made of hard glass, hard polyethylene plastic and stainless steel tubes. The centrifuge is equipped with a drive motor, a timer, a regulator (speed indicator). This type of centrifuge is mainly used to collect microorganisms, cellular debris, cells, large organelles, sulfuric acid precipitates and immunoprecipitation.

Types of Centrifuges a Laboratory May Need

Centrifuges, non-refrigerated

They are easy to handle and compact centrifuges, that is, they are small centrifuges and do not have refrigeration so they usually operate at room temperature. Reaches speeds between 4000-5000 rpm. They are used for general laboratory applications, such as separating large particles such as cells, cell suspensions, separating sera, plasma, urine, sperm, among others. 

So they are used in the chemical, environmental, pharmaceutical industry, in clinics and laboratories. They can use tilting and fixed-angle rotors.

Refrigerated centrifuges

Centrifugation is a separation technique used to isolate or concentrate suspended particles in a liquid, taking advantage of the different displacement speeds depending on their shape, size or weight when subjected to centrifugal force. Centrifugal force is the force exerted on a body when it rotates around an axis.

This force, whose magnitude is directly proportional to the mass of the body, the radius of gyration and the speed of rotation (or angular), is perpendicular to the axis and tends to move the body away from it. Centrifugal force can accelerate the sedimentation process of particles that tend to do so spontaneously (density higher than liquid), or those that tend to float (density lower than liquid).

Our Best Selling Centrifuge

  • When the centrifuge is in the pre-cooling state, the cap of the centrifuge must be closed. Once the centrifuge is finished, the rotor must be placed on the test bench and the residual water must be dried in the cavity.
  • Rotating head During pre-cooling, the rotary head cover can be placed on the centrifuge platform or on the test bench. Do not screw it into the swivel head, because once it is accidentally activated, the rotary head cover will fly and cause an accident.
  • After tightening the threaded lid, be sure to touch the space between the rotor and cover with your fingers. If there is a space, unscrew and press again until the space is confirmed before the centrifuge can be started.

Centrifuges in operation

Centrifugation has been the most important process for isolating olive oils since their introduction in the 1960s. It is a mechanical process of separating solid particles of liquids, used to separate high oil content components, not soluble in water. Separation requires the use of a centrifuge, built to allow the flow of liquid through different compartments, separating solids and liquids and allowing separation, based on viscosity and density.

It should be noted that in Kalstein we have the ideal equipment, which has microcomputer control, brushless DC motor, stable operation, low noise level and high speed precision. Touch panel, programmable operation, operation data can be configured according to demands and are stored automatically.
