The MININEPH is a bench top laser nephelometer capable of performing a range of quantitative serum protein assays simply, accurately and economically. It is ideal as an alternative method to Radial Immunodiffusion (RID) and other manual techniques, or to back up a main analyser by performing low volume tests. With reaction times between 15 seconds and a few minutes, assays are completed rapidly and results reported quickly. A rapid swipe card system allows instant programming of assay parameters and provides a calibration curve for each specificity. The user is then guided through the protocol by prompts displayed on the LCD in a choice of 6 operational languages.
