Laboratory Mixers

Laboratory mixers are indispensable tool used in chemical and industrial laboratories. They are used for technological advancement, specifically in the areas of production of food, building materials like cement, pharmaceuticals, and several others.
Lab mixers caters to the various need of the pharmaceutical industry such as homogenizing, dissolving, emulsifying, and disintegrating. Pharmaceutical lab mixers are preferred because of their speed range, operating mode, and dimensions. And it is usual to find several types of industrial lab mixers but the basic elements that are found in laboratory mixer are speed adjustment controls, mixing blades, feeding hopper, and timer. To summarize the functionality of lab mixers, they should be able to perform a wide range of applications, efficiently and safely.
Display features of laboratory mixers:
  • Video display
  • Digital and
  • Analog
Some of the common applications of lab mixers are:
  • Granulation
  • Heating
  • Coating
But one of the common features in all the laboratory mixers is that they are driven by direct gear mechanisms, which can be easily controlled to reach certain speed or velocity. This is usually done performed with the help of a hand lever as the controlling device during operations.

Types of laboratory mixers:
  • In line
  • Batch
  • Planetary
  • High shear
  • Three roll lab mixers, and so on.
For all of the above types of mixers, there are certain industrial terms common to them. Specifications, capacity, height and weight varies from model to model. But the specification range, include speed range, maximum torque, motor power shaft and diameter, which are approved standards. Motor power in each lab mixer is also different, it actually means the energy or capacity level of motor that drive the laboratory mixer.

Advantages of laboratory mixers:
  • They help to get rid of air and also act as smoother to the finished products.
  • They give high gloss looking to products in pharmaceutical companies.
  • They churn out products homogeneously, at quicker rate.
  • It also ensures that products can’t be contaminated.
