About Steridose

Steridose was founded in the late 1970’s in Sweden with the purpose of developing innovative process components for aseptic manufacturing.  Steridose introduced technologies such as magnetically driven mixers and radial type diaphragm valves to the pharmaceutical industry in the 1980’s.  In the early 2000’s, the company became part of the Roplan Group, consolidating development and manufacturing.  Through the years, Steridose has developed an extensive distribution network with representation in over 30 countries and has a vast equipment installed base. Steridose continues innovating based on the feedback and needs of customers. In 2015, Roplan and Steridose formed Velcora Group.

The most common purpose of agitation in bio-pharmaceutical processing is liquid/liquid and solid/liquid blending (solutions and suspensions). Agitators are performing their duty while submerged in a fluid phase, and consequently designed for this intended use, considering that running in air would not fit any purpose. This article discusses different bearing designs and materials of construction typically available. Click here to read White Paper.

The Sterimixer may be the most widely used magnetically coupled mixer for bio-pharmaceutical applications world-wide.  It consists of the following major components: impeller, bearing, weld-plate, drive unit and control box.  All wetted parts of the impeller and the weld-plate are made of AISI 316 L (EN 1.4404).  Interchangeable impeller designs are available.
