摘要： An object of the present invention is to provide a liquid injection attachment enabling a simple liquid injection into a feed port by merely mounting the attachment onto the distal portion of a pipette or a pipette tip when liquid is injected into the feed port, as well as capable of exhibiting an excellent sealing performance without a risk to deform or damage the pipette or the pipette tip, to thereby suppress leakage of liquid during the liquid injection. The object is achieved by a liquid injection attachment removably mounted on a pipette injecting liquid into a feed port through which liquid is introduced or on a pipette tip fitted to the pipette, the attachment including a tubular attachment body having at its distal end a liquid outlet and having at its proximal end an insertion port into which a distal portion of the pipette or of the pipette tip is inserted; and a gasket formed from a rubber-like elastic body disposed around the liquid outlet of the attachment body.

摘要： The present invention addresses the problem of providing an attachment structure that ensures a large crushing amount of a fluid injecting attachment for sealing around an inlet, in which the fluid injecting attachment will not be deformed or damaged. This problem is solved by an attachment structure of a pipette 100 and a fluid injecting attachment 1, which includes a first cylindrical hole 21 into which a tip end portion 101 having a tapered shape of the pipette 100 is inserted, on one end side of an attachment main body 2 formed in a cylindrical shape by a rubber elastic body, and a second cylindrical hole 22 that is communicated with the first cylindrical hole 21 and out through which fluid inside the pipette 100 flows, on the other end side, and a step portion 23 between the first cylindrical hole 21 and the second cylindrical hole 22 due to the second cylindrical hole 22 being formed with a smaller diameter than the first cylindrical hole 21, in which a washer 3 is provided on the step portion 23, the tip end portion 101 of the pipette 100 is inserted through the first cylindrical hole 21 and inserted into the washer 3, and while the tip end portion 101 is in a state inserted into the washer 3, the second cylindrical hole 22 has a crush allowance 24 farther toward a tip end side than the tip end portion 101.
