Janssen Pharmaceutica

When preparing samples organic solutions must often be mixed according to certain calibrated procedures in the laboratory. In order to replace the manual shaking with a mechanical system, Janssen Pharmaceutica asked Peira to develop a test bench.

Situation

When preparing samples organic solutions must often be mixed according to certain calibrated procedures in the laboratory. In order to replace the manual shaking with a mechanical system, Janssen Pharmaceutica asked Peira to develop a test bench.

Solution

The apparatus, which is a stand-alone device, offers a standardised method for determining the re-dispersion of pharmaceutical suspensions. The sideways movement of the new equipment has a radius of around 300 mm (which corresponds roughly to the human shaking movement) and it can shake for a maximum of 30 seconds. The drive belt is fitted with a universal holder and can work at frequencies of up to 5 Hz.

Result

The apparatus, which does not require a display, is fitted with just three push-buttons so it is very simple to operate. The end result is a very compact, smart device which was designed and produced to fully meet pharmaceutical GMP guidelines. It is thought to be the first time that an apparatus with such impressive dynamics has been designed with just one belt.
