  • Patent number: 10539584
    Abstract: A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced. As a result of the reduced friction, the wear of the tip of the nozzle is minimized.
