Title:
HEAT WEIGHT MEASURING INSTRUMENT AND SAMPLE CONTAINER EXCHANGING METHOD IN THE INSTRUMENT
Document Type and Number:
Japanese Patent JP3727141
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automate the replacement of a sample container by facilitating the replacement by improving a soaking cylinder.
SOLUTION: Below a sleeve 10 which is fixed perpendicularly, a support rod 5 which extends vertically upward while having a balance coupled with its lower end is run through and at the upper end of the support rod 5 which projects from the sleeve 10, an upper pan 6 where a sample container 15 is placed is provided and at the upper end of the sleeve 10, the soaking cylinder 30 which surrounds the upper pan 6 and sample container 15 is arranged. Of this heat weight measuring instrument having an electric furnace for heating a sample in the sample container 15 through the soaking cylinder 30 arranged outside the soaking cylinder 30, the soaking cylinder 30 is engaged with the upper end of the sleeve 10 detachably along the top/bottom direction, a tapered part 33 which decreases in diameter downward is formed at the inner periphery of the sample container storage hole part 32 of the soaking cylinder 30; and the diameter of the upper large-diameter part 33a of the tapered part 33 is set larger than the external diameter of the sample container 15 and the diameter of the lower small-diameter part 33b of the tapered part 33 is set smaller than the external diameter of the sample container 15 and larger than the external diameter of the upper pan 6. Consequently, when the soaking cylinder 30 is lifted, the sample container 15 is lifted together.
