Title: PIPETTE TIP AND LIQUID INJECTION METHOD
Abstract:
The present invention provides a pipette tip and a liquid injection method capable of reliably preventing the adhesion of residual droplets of an ejection port at the injection port of a sample container. The pipette tip is provided with a main body part and protruding parts (15). In the main body part are provided a flow passage through which liquid from a syringe flows and an ejection port (20A) that ejects to the outside the liquid that has flowed through the flow passage. The ejection port (20A) is provided at the distal end part (20). The protruding parts (15) are provided at the distal end part (20) so as to protrude in the ejection direction (ED) of the liquid from the periphery of the ejection port. The protruding parts (15) are partially arranged about the center axis (CA) of the main body part. Even when residual droplets have adhered to the ejection port (20A), since the protruding parts (15) guard the periphery of the residual droplets, there is no adhesion of the residual droplets at the injection port of the sample container.
