    Microcentrifuge

    Overview Knowledge Standards Terms
    The microcentrifuge generates centrifugal force through high-speed rotation, causing components of different densities in the sample to settle in layers within the capillary. An optical detector is used to record the sedimentation process. It is employed to determine the particle size distribution and dispersion stability of liquid samples such as coatings and inks, and to analyze the suspension characteristics of pigments and fillers in quality control.
    Selection
    When selecting, consider the sample characteristics to match the speed range, confirm the accuracy of the optical system based on detection requirements, check whether the temperature control system meets the stability requirements of the sample, compare the sample capacities of different models with daily detection volumes, and evaluate the suitability of the operation interface and data output format.

    Key steps for measuring the efflux time of varnish using a viscosity cup method
    This article introduces the method for measuring the outflow time of varnish using a viscosity cup. The principle is based on Poiseuille's law, where viscosity is estimated by recording the time it takes for the liquid to completely flow out from the small hole at the bottom of the cup—longer times typically indicate higher viscosity.
