Food Manufacturing. The food industry is ever changing. Regulation changes seem to be constant and the need for 3rd party services is becoming more important.

Usually liquid layer thickness in a centrifuge is low, so we can assume that R = rav. Thus it is possible to make a replacement, where F is sedimentation area To obtain maximum average throughput of a filtering centrifuge tf is usually assumed to be equal to the aggregate time of centrifugation (tc)

Centrifuge calibration- it's what we have been doing for over 30 years. During this time, we have frequently been asked the same question: how often should I calibrate my centrifuge in any given year?

interesting film from scientists at EPFL that have managed to model the shape of the wave created in a glass of wine while swirling it. They figured out that given parameters allow reproducing the exact wave form, whatever the size of the recipient. These finding are useful to better calibrate orbital shaking bioreactors for cell culture.
