Abstract
The utility model relates to a suction ball with a concave suction nozzle, which is used for a transfer pipette to suck liquid, and belongs to the technical field of a structure of a chemical examination instrument appliance. For the suction ball with the concave suction nozzle, a concave cavity is arranged in the suction nozzle and an air outlet hole in a suction ball bag is arranged at the circle center of the inner end of the concave cavity, wherein the section of the concave cavity is of a circular shape; the caliber of the outer end of the concave cavity is large; and the caliber of the inner end of the concave cavity is small. The suction ball with the concave suction nozzle is made of an elastic rubber material. When the suction ball with the concave suction nozzle is in use, an upper orifice of the transfer pipette can be inserted into the concave cavity of the suction ball, the air outlet hole in the suction ball bag is just arranged in the upper orifice of the transfer pipette, and the suction nozzle of the suction ball is tightly contacted with the upper orifice of the transfer pipette by utilizing the elasticity of the rubber material, so that solution can be easily sucked into the transfer pipette. The suction ball with the concave suction nozzle has a scientific and reasonable structure, is simple and convenient to operate and can be suitable to the matching with various specifications of transfer pipettes.
Description
Technical field
The utility model relates to a kind of suction ball that is used for the band spill suction nozzle of pipette, extract liquid, belongs to assay apparatus articles for use technical field of structures.
Background technology
Breadboard checked operation often need pipette certain quantity solution with pipette, and inhaling ball is necessary tool in this operation, and the used suction ball in laboratory is the taper suction nozzle at present; It is suitable for reading during operation the taper suction nozzle to be inserted suction pipe; Discharge and inhale portion gas in the ball, utilize negative pressure that solution is sucked in the pipette, and for the less pipette of some specifications; The taper suction nozzle of inhaling ball can't insert its upper orifice, and pipette then can't be got liquid.
Summary of the invention
The purpose of the utility model is to solve the deficiency that above-mentioned prior art exists, and a kind of suction ball with the spill suction nozzle is provided, and gets liquid with the pipette that adapts to all size.
The utility model is realized through following technical scheme:
The suction ball of band spill suction nozzle, its special feature are to be provided with in the suction nozzle cross section and are re-entrant cavity 1 circular and that bore imperial palace port footpath in outer end is little, and venthole 2 is located at the inner circle centre position of re-entrant cavity 1 in the suction sacculus.
The suction ball of said band spill suction nozzle adopts elastic rubber material to process.
The suction ball of this structure is when using the pipette of small dimension; Can the upper orifice of pipette be inserted in the re-entrant cavity 1 of inhaling ball; Inhaling the interior venthole 2 of sacculus is just putting in the upper orifice of pipette; By the elasticity of elastomeric material, the suction nozzle of inhaling ball closely contacts with the pipette upper orifice, can easily solution be sucked in the pipette.
The beneficial effect of the utility model: scientific and reasonable for structure, easy and simple to handle, can fit and the supporting use of the pipette of plurality of specifications.
Description of drawings
Fig. 1: be the utility model structural representation;
Among the figure: 1, re-entrant cavity, 2, venthole.
The specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the utility model, be used for the formation of the utility model is further specified.
Embodiment
The suction ball of the band spill suction nozzle of present embodiment is provided with a cross section and is re-entrant cavity 1 circular and that bore imperial palace port footpath in outer end is little in its suction nozzle, inhale the inner circle centre position that the interior venthole 2 of sacculus is located at re-entrant cavity 1.The suction ball of band spill suction nozzle adopts elastic rubber material to process.
The suction ball of the band spill suction nozzle of present embodiment is when using the pipette of small dimension; Can the upper orifice of pipette be inserted in the re-entrant cavity 1 of inhaling ball; Inhaling the interior venthole 2 of sacculus is just putting in the upper orifice of pipette; By the elasticity of elastomeric material, the suction nozzle of inhaling ball closely contacts with the pipette upper orifice, can easily solution be sucked in the pipette.It is scientific and reasonable for structure, and is easy and simple to handle, can fit and the supporting use of the pipette of plurality of specifications.
