PURPOSE:To save manhours and to improve safety, by tumbling every one of many sample containers, which are attached to a sample-container attaching board, several times, and picking up the stirred sample. CONSTITUTION:When a power source is turned ON, a sample-tube attaching board is rotated, and the first sample tube 205 is brought to a position facing a pickup needle 209 and stopped. A sample turning lever 211 is reciprocated back and forth several times at an angle of 90 deg. with a pin 212 as a shaft. The sample tube 205 is tumbled several times and the sample is stirred. Thereafter the sample tube 205 is stopped at an approximately horizontal state. A supporting tool 207 for the pickup needle and the like is made to advance, and an air feeding needle 208 and the pickup needle 209 are pierced through the rubber cap of the sample tube. An air feeding pump is actuated, and the air is fed into the sample tube 205 through the air feeding needle 108. The sample 214 is sent to an automatic measuring device through the pickup needle 209 and a connecting tube. Therefore manhours are saved and safety for dangerous samples can be improved. |
