LIQUID SAMPLING DEVICE FOR MANUAL MANIPULATOR

摘要

PURPOSE:To sample liquid by a manual manipulator by pushing down a jug against a hollow needle linearly in parallel and securely sticking the jug into the hollow needle. CONSTITUTION:The upper part of the opening part 8a of a jug holder 8 is pressed toward a support arm 10a by the hand part of the manipulator and the jug holder 8 is fallen down backward to open the upper part of the needle holder 5. Then a jug 9 is mounted on a jug receiving opening 7 by a hand part and a chain 20 is gripped and drawn to this side to cover the jug 9 with the jug holder 8. The chain 20 is further drawn down to apply a linear downward force to a pusher 12 through an arm 14 for the pusher and a support rod 13, and the jug 9 is pressed down against the resistance of an elastic material 6 to stick into the hollow needle 3a. A vacuum is produced in the jug 9, so the sample liquid in a liquid reservoir container 1 is sucked in through the hollow needle 3a.
