Device for calibrating a microorganism quantifying apparatus

Abstract

A microorganism-collecting chip, for efficiently collecting microorganisms from a test sample and accurately detecting and quantifying the collected microorganisms, comprises a filter for removing contaminants and a filter for trapping microorganisms. A microorganism-collecting kit comprises the foregoing microorganism-collecting chip and a suction filtration unit, which may be a negative pressure tube provided at an opening with a rubber stopper. The microorganism-collecting chip has a liquid specimen injection container for injecting a liquid specimen and a hollow needle capable of penetrating the rubber stopper mounted at the opening of the negative pressure tube. The liquid specimen injected into the liquid specimen injection container is suction-filtered with a pressure of the negative pressure tube. Contaminants are removed with the filter for removing contaminants, and microorganisms are trapped on a filter for collecting microorganisms. The microorganisms trapped on the filter for collecting microorganisms are then detected and quantified by using a unit including the filter for collecting microorganisms.
