The versatile lab mixer

April 16, 2013

Lab mixers and blenders are quite a classic category of manufacturing equipment. Their designs and configurations have been perfected over decades and even centuries, till they exist in the forms that we recognize today. In the modern age, these mixers are needed for the lab scale production of processed food products, adhesives and sealants, batteries, ceramics, cosmetics, personal, healthcare and pharmaceutical products, plastics, metals, and the list goes on.

Mixers are categorized as suitable for industrial scale or lab scale use based on the capacity of material they can handle in one go. The typical lab mixer handles anything between 1 and 50 gallons. In fact there is nothing that may be called a ‘typical’ lab mixer; the name covers a whole range of equipment, from simple stirrers that are powered by air motors, to electric mixers. The latter is the most popular and most versatile category, as it can work at different speeds, and includes electronic transmissions, digital displays and standard controls as part of the entire package.

A lab mixer system is comprised of a few generic components. The first of these is the stand, which is generally a base with a vertical rod. It may not sound like much, but it is the key to keeping the mixer still, which in turn is the key to a successful agitation of the ingredient materials. The stand can of course be varied in height. The second component of the system is the mixer clamp, which joins the vertical rod of the base with the horizontal rod of the stirrer. The third component is the body of the mixer itself. The fourth is the shaft, which is made of a half inch diameter ground and polished stainless steel rod. The lab stirrer impellers make up the fifth and final component, and are responsible for converting the power of the mixer to shear or pumping force within its contents.

These components may either be purchased separately and assembled on the site, or bought together as a package deal. Setting the entire system up is a fairly complicated process, and marketing brands usually offer to send a technician to do the same for the customer in order to make things easier. The customer can choose from many different varieties of the components described, and select one based on his particular requirement. If he is unsure, the manufacturing or marketing company or brand can advise him regarding the same.
