  • Understanding Cuvette Volume Material Path Length Etc

    For instance a 4 mm cuvette is a cuvette with an external size of 12.5 mm x 12.5 mm and an inner size of 4 mm x 10 mm. Such a 4 mm cuvette will require a liquid volume of 1.4 mL per – 45 mm of height; similarly a 1 mm cuvette corresponds to a liquid volume of 0.35 mL per – 45 mm of cuvette height. See the examples below:

  • Mill grain under realistic conditions for preparing

    Reproducible sample preparation for determining moisture. Due to the milling system’s special design heating of the grist and loss of moisture during the milling process is reduced. The SM 4 is therefore especially well suited to preparing samples for moisture determination as well as for analyses of protein or fat content for example.

    Timing: Most samples that are smaller than the size of a fist are processed through the Wiley Mini-Mill. On the average 1 minute per sample if less than 15 grams or 3-4 minutes for samples of 100-150 grams. Samples larger than two fists are sent through the model 4 Wiley Mill. Average time is 4-5 minutes per sample.
