The magnetic stirrer is an equipment designed primarily to confirm to GMP standards in the pharmaceutical,biotechnology, and food industries, which is featured by small size, reasonable structure, excellent perfor-mance and reliable use. It is a stirring device applicable to all kinds of stainless steel reaction tanks and liquid tanks. It is mainly composed of internal magnetic steel, external magnetic steel, isolation sleeve and transmis-sion motor.
KET-type sanitary magnetic stirrer contact material parts are all made of stainless steel 316L /304, and it is through the permanent magnet coupling to drive the stirring shaft to work. It uses the static seal of the insulat-ing sleeve isolation method to replace the dynamic seal of the drive shaft which completely solves various unavoidable leakage problems of mechanical seal.
The stirring impeller of the magnetic stirrer rotates to generate a vortex, and the dissolvable powder or liquid material is sucked into the vortex and rapidly absorbed into the stirring impeller. The centrifugal force of impel-ler rotation impacts the material from the outer diameter of the impeller to the tank wall in the form of radiation.
The material rises and circulates with the collision force, and is then sucked back to the suction end of the impeller. The impeller's thrust causes the material to move and stir continuously, and is homogenized, mixed,dissolved and dispersed, and finally forms a stable and delicate product.
