  • Petri dish
    Publication number: 20040146965
    Abstract: A self-contained petri dish container for growth of microorganism cultures. The petri dish container has a lid for the container which fits sufficiently snug to seal the container from contaminants, container pad for growth media containment positioned within the container and the container pad is made of sterile glass microfiber material, as opposed to conventional cellulose pads.

  • Method of using a water testing capsule using water soluble film membranes
    Patent number: 6004820
    Abstract: A capsule package and a touch-free method for water analysis. It allows for addition of dry ingredients and aqueous test reagent without any human intervention, and therefore substantially decreases the possibility for analysis error. Furthermore, it eliminates physical contact between the operator and the chemical reagent, thereby enhancing safety. Importantly, the packaging system allows for film protection of a water soluble membrane so that it is damage free prior to use.
    Type: Grant

  • Method for chloride ion removal prior to chemical oxygen demand analysis
    Patent number: 5683914
    Abstract: A method of pretreating aqueous chemical oxygen demand (COD) samples to remove the risk of potential chloride ion interference. The method comprises acidifying an aqueous COD test sample, and thereafter passing the acidified sample through a source of pentavalent bismuth (Bi.sup.5+) such as sodium bismuthate.
