PROBLEM TO BE SOLVED: To provide a liquid dispensing and distributing device which can carry out the connection and the removal of a nozzle chip rapidly, as well as making the device in a very simple structure. SOLUTION: In a device in which a nozzle chip is installed to a pipet nozzle so as to dispense and distribute a liquid such as a reagent, and then, the nozzle chip is returned to a housing, the nozzle chip 26 to connect and remove to the pipet nozzle 34 has a large part 27 larger than the pipet nozzle 34, and a small part 28 smaller than the large part 27, an entrance port 31 for nozzle chip with the width at the level to pass the small part 28, and not to pass the large part 27, is provided at the side of a hole 22 for holding where the large part 27 of the nozzle chip 26 is hitched, a removing plate 38 furnishing a hole 39 for removal with the level to pass the pipet nozzle 34 but not to pass the nozzle chip 26 is set by fixing, at the upper part of the hole 22, and when the nozzle chip 26 is removed from the pipet nozzle 34, the pipet nozzle is inserted to the hole of the removing plate 38, as well as the pipet nozzle 34 is inserted in the hole through the entrance, the nozzle chip 26 is removed from the pipet nozzle 34 by raising the pipet nozzle 34, and the nozzle chip 26 is returned to the hole. |
