Latest App Notes & Case Studies

The turbidity of a liquid sample is traditionally measured either with a nephelometer or a photometer. The measure of turbidity (also called optical density, OD) refers to the scattering of light from the particles of the measured sample. When measuring turbidity of a bacterial culture, the amount of scattered light is directly proportional to the number of bacterial cells in the sample.

Oxidative stress has been demonstrated to be involved in many diseases including atherochlerosis, Parkinson disease and cancer. Oxidative stress is caused by an imbalance between the production of reactive oxygen and a biological system’s ability to detoxify the reactive intermediates, or easily repair the resulting damages.

Biobanking is becoming a central element in the study of patient genetic data and clinical application of genetic research. Until recently, collections of DNA samples have tended to be fairly small and localized with varied sample containers that were unsuitable for an increasing throughput and automated system use.

With the storage of biological samples such as DNA, protein, blood fractions and viable cells becoming commonplace. The need to store them at lower temperatures has resulted in reading challenges for traditional rack readers.
