  • Method and apparatus for collecting and chilling wastewater and like fluid samples
    Patent number: 6658876
    Abstract: A method and apparatus for collecting and chilling wastewater samples and the like provides an insulated sample container vessel that has cooling coils therein for direct contact and heat transfer with a liquid in the container to rapidly cool the liquid. A refrigeration unit keeps the cooling coils cool. The liquid can be a sample which is required to be stored at 1-3 degrees Centigrade. The chiller is different from similar chillers in that the cooling coils simply are inserted in an insulated container, and can be removed therefrom when it is desired to transport the sample. The sample remains cool during transportation even without the cooling coils. The cooling coils are arranged in the ice chest such that coolant from the chiller enters through the upper coils and exits through the lower coils, causing the liquid sample in the upper part of the container to cool more than the sample in the lower part of the container.
