In a typical analytical laboratory, sample and solution preparation is a crucial part of many processes, lying at the heart ofaccurate, precisedata generation. Errors in sample prep steps have various consequences, particularly in regulated environments, where any non-compliance may require time-consum...
the purity of the reagents used, they should be tested by standard methods for the impurities that might cause errors in the determinations. In any analytical laboratory it is essential to maintain stocks of solutions of various reagents: some of these will be of ...
A measuring cell has been designed for fast preparation of multicomponent solutions and express characterization of them in three parameters: their electrical conductivity, optical density, and viscosity. The relative error in determining the electrical conductivity and the optical density is 5–10%, and...

A laboratory instrument for the preparation of samples includes a base housing with a work compartment enclosed by protective walls, at least one multifunctional work head having the ability to turn a
(Kern Microtechnik, Germany). Due to the high positioning accuracy of ± 0.001 mm and a working accuracy of ± 0.0025 mm, the system is particularly suitable for high-precision micromachining processes. By setting up the 3-axis tool machine in a temperature-controlled laboratory on a...
