Sample Preparation

ABOUT SAMPLE PREPARATION
  • Sample preparation is the method used to treat product prior to analysis. Typically this step of the process is done in a laboratory setting after harvesting is complete
  • Preparation includes evaluating quality and purity, and making physical changes to the product so that it is suitable for the next processing steps
HOW UNITED (PRODUCTS) CAN HELP
  • Pulverize leaves for quality and potency testing and to place in edibles (Centrifuge Tubes, Mortars and Pestles)
  • Transfer chemicals accurately for use in laboratory analysis protocols (Pipettes)
  • Storage for a wide variety of chemicals and for finished product (Reagent Bottles)
