  • Describing Solutions

    Describing SolutionsPresentation

    Most scientists use a common language of measurement, called the International System of Units. David Caprette, PhD, shows you how to use this language to describe solutions.

  • Introduction to Chemical Mixtures

    Introduction to Chemical MixturesPresentation

    Dr. David Caprette describes the types of mixtures, and their properties, that might be encountered in a biological laboratory, and discusses basic equipment for solution making.

  • Mixtures


    What is a mixture, how is a mixture made and separated, and what are some common mixtures? Learn these answers to these and other questions in this engaging video.

  • Quantitative Methods: Part 1. Solutions and Dilutions

    Quantitative Methods: Part 1. Solutions and DilutionsPresentation

    David Caprette, PhD, discusses the types and properties of mixtures prepared and/or encountered in a biological laboratory. He also introduces basic lab equipment, terms and concepts related to formulas, and the concept of the mole.

  • Quantitative Methods: Part 2. Diluting Solutions

    Quantitative Methods: Part 2. Diluting SolutionsPresentation

    It is relatively easy to work out dilution problems once a solid frame of reference is established. David Caprette, PhD, explains the process.
