Abstract
The present invention provides a pipette tip structure. With the pipette tip structure, sealing of a pipette tip and a pipette is good, such that no leakage is ensured, a liquid is saved, and cleanliness of the internal liquid is ensured so as to smoothly perform the subsequent operation. The pipette tip structure comprises a tip apex, a tip connection section and a tip tail sealing section, wherein both ends of the tip connection section are respectively the tip apex and the tip tail sealing section. The pipette tip structure is characterized in that the ring surface of the tip tail sealing section sequentially comprises an internal opening conical surface, an internal cylindrical surface, a triangular slot surface, an external cylindrical surface, and an external opening cylindrical surface from inside to outside.
Description
Technical field
The present invention relates to the technical field of cell culture apparatus, be specially the liquid-transfering sucker structure.
Background technology
Liquid-transfering sucker is used for transfer liquid.Supportingly use at pipette, liquid is transferred to another place from a place.Suction nozzle and the pipette of existing liquid-transfering sucker directly are set with, and the link of liquid-transfering sucker is set in the end of pipette, owing to only by single face seal, so that sealing is poor, causing the waste of liquid, easily pollute simultaneously internal liquid, affect subsequent operation.
Summary of the invention
For the problems referred to above, the invention provides the liquid-transfering sucker structure, it guarantees the cleaning of internal liquid, so that subsequent operation is carried out smoothly simultaneously so that the good seal between liquid-transfering sucker and the pipette is guaranteed to have saved liquid without leaking.
The liquid-transfering sucker structure, its technical scheme is such: it comprises, and suction nozzle is sharp-tongued, suction nozzle linkage section, suction nozzle tail seal section, two of described suction nozzle linkage section is sharp-tongued, the suction nozzle tail seal section of tail suction nozzle respectively, it is characterized in that: the anchor ring of described suction nozzle tail seal section be followed successively by from the inside to the outside taper seat, inner circular cylinder, triangle draw-in groove face, external cylindrical surface, the outside face of cylinder of dehiscing of dehiscing, inside.
After using structure of the present invention, since the anchor ring of suction nozzle tail seal section be followed successively by from the inside to the outside the inside taper seat of dehiscing, the inner circular cylinder, triangle draw-in groove face, external cylindrical surface, the face of cylinder of dehiscing, outside, it is so that the inner taper seat of dehiscing is close to the end anchor ring of pipette, triangle draw-in groove face both sides inner circular cylinder and external cylindrical surface are close to the outer ring surface of pipette afterwards, it is so that form two-layer tight seal structure, so that the good seal between liquid-transfering sucker and the pipette, guarantee without leaking, saved liquid, guarantee simultaneously the cleaning of internal liquid, so that subsequent operation is carried out smoothly.
Description of drawings
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises that suction nozzle is sharp-tongued 1, suction nozzle linkage section 2, suction nozzle tail seal section 3, two of suction nozzle linkage section 2 is sharp-tongued 1, the suction nozzle tail seal section 3 of tail suction nozzle respectively, the anchor ring of suction nozzle tail seal section 3 be followed successively by from the inside to the outside taper seat 4, inner circular cylinder 5, triangle draw-in groove face 6, external cylindrical surface 7, the outside face of cylinder 8 of dehiscing of dehiscing, inside.
Claims (1)
