In the field of consumable materials for automatic analytical instruments, transparent plastic cuvettes having increased scratch resistance and a method for producing same includes contacting exclusively an outer surface of the transparent plastic cuvette with a liquid comprising at least one surfactant or with a triglyceride and subsequently drying the outer surface such that scattered-light optical properties of the transparent plastic are not adversely affected.

Plastic cuvettes having increased scratch resistance and methods for increasing the scratch resistance of same

A nephelometry system for an automatic analysis device may include a light source, a stop, and a photodetector on the one hand and a receptacle position on the other hand that are movable relative to one another in order to improve the measurement quality of a nephelometry system. The nephelometry system may determine a location of an interval I of recorded light intensity signals which only contains light intensity signals that emerge from a scattered portion of a light beam after passing through a measurement cell placed into the nephelometry system. Methods of nephelometric determination of an analyte are also provided, as are other aspects.
