Abstract
The utility model discloses a tip, particularly relates to a tip used on a pipette, and aims to provide a tip with accurate liquid suction and discharge and is convenient to dismount from the pipette or fix. The tip comprises an upper taper pipe with 15-degree taper and a lower taper pipe with 20-degree taper, the upper taper pipe and the lower taper pipe are integrally connected, a connector connected with the pipette is arranged at the other end of the upper taper pipe, multiple raised ribs are arranged on the outer surface of one end, connected with the pipette, of the upper taper pipe, and the length directions of the raised ribs are the same with the length direction of the tip. The tip has the characteristics of simple structure, convenience in use, reasonable design and the like.
Description
Technical field
The utility model relates to a kind of suction nozzle, the suction nozzle using on especially a kind of pipettor.
Background technology
The suction nozzle of the pipettor of selling on market is mainly used on pipettor, but at present suction nozzle on the market exists and while moving liquid, controls accurately not, when suction nozzle is installed to pipettor or takes away in the time that people's hand is perspired simultaneously, by larger power, when serious, can damage suction nozzle.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of imbibition and fluid accurate suction nozzle, and pulls down or the suction nozzle of convenient fixing from pipettor.
In order to achieve the above object, the suction nozzle that the utility model is designed, it comprises cone tube and lower cone tube, and the tapering of upper cone tube is 15 degree, and the tapering of lower cone tube is 20 degree; Upper cone tube and lower cone tube link into an integrated entity, the other end of upper cone tube is provided with the interface being connected with pipette, one end outer surface joining at upper cone tube and pipette is provided with many protruding muscle, and the length direction of this protruding muscle is identical with the length direction of suction nozzle.
The liquid sucting port internal diameter 0.30mm of the lower cone tube of suction nozzle is best, and liquid sucting port is crosswise for preferred certainly; This suction nozzle is made up of polypropylene material.
The inwall of the interface of upper canalis spinalis body is stepped, is applicable to the pipettor of different model.
According to the above, the suction nozzle of the utility model gained, has the features such as simple in structure, easy to use and reasonable in design.
