TRACE AMOUNT OF LIQUID DISCRIMINATING DEVICE

摘要

PROBLEM TO BE SOLVED: To automate discriminating operation which has been performed visually so far. SOLUTION: The bottom-surface material of a vessel 10 of a trace-amount liquid discriminating device is transparent, the bottom surface of the vessel 10 is smaller in cross-section as approaching a bottom part, and a light source 20 is allocated on a vertical line passing through the center of the vessel 10. Meanwhile, a photo-detecting element 40 is allocated near a condensed point when a specimen 30 is reserved in the vessel 10, and the amount of specimen is discriminated based on photo-detecting amount of the photo-detecting element.
