Abstract
The utility model provides a rubber-head burette for sucking or dropping a small amount of liquid reagent, which includes a burette body, a suction nozzle, and a ball-saccate rubber head; wherein, the ball-saccate rubber head is sleeved at the upper end of the burette body. The burette is characterized in that the suction nozzle is made into a bent shape. The bent-head burette is added with new functions as well as keeps the original functions for dripping reagent and transferring reagent, when the liquid or mash in a bottle or container is less, the liquid or mash can be sucked clearly by the bent suction nozzle, in particular the bent suction nozzle can conveniently suck off the mash which can easily adhere to the wall of the container.
Description
Technical field
The utility model relates to a kind of chemical laboratory or Health Service Laboratory instrument, specifically is a kind of glue head dropper that is used to draw or drip small amount of liquid reagent.
Background technology
Glue head dropper claims Capsule dropper (someone claims the glue head straw) again, it is a kind of instrument that is used to draw or drip small amount of liquid reagent, the dropper structure of prior art is very simple, a rubber sacculus glue head directly is enclosed within on glass or the plastic dropper main body exactly, the downward end of dropper is the suction nozzle that diminishes gradually, in chemical experiment, extensive use in medical experiment and the Bioexperiment, be earlier sacculus glue head to be clutched with hand when using, the exclusive segment air, suction nozzle is reached below the liquid (or paste materials) of bottle or container, unclamp sacculus glue head, liquid can be drawn in the dropper main body from suction nozzle.The shortcoming that this dropper exists is: because the dropper main body is a straight tube to suction nozzle, when the liquid of bottle or container or paste materials were few, dropper was inhaled unclean, and particularly paste materials is bonded on the chamber wall easily, causes suction unclean.
Summary of the invention
The purpose of this utility model is to provide a kind of dropper, can overcome the weak point of existing straight tube, and it can be used at the original dropping of common dropper and mobile all ingredients has increased new function.
The technical solution of the utility model is achieved in that dropper comprises dropper main body, suction nozzle and sacculus glue head, and sacculus glue headgear is in the upper end of dropper main body, is characterized in that suction nozzle makes crooked shape.
The angle of above-described suction nozzle sweep is 80 °-150 °.
Above-described suction nozzle is the extension of dropper main body, or is enclosed within the part of dropper main body.
Above-described dropper main body is straight tube or fat tripe pipe, and the dropper principal length designs as required.
Above-described dropper main body can be made with glass or transparent plastic, and the dropper main body is marked with scale, also can not have scale.
The utility model advantage compared to existing technology is: the suction nozzle of design dropper lower body part is made crooked shape, and can keep the dropper original function to drip on the basis of reagent and transfering reagent has increased new function again, can remedy the deficiencies in the prior art.When the liquid of bottle or container or paste materials are few, can blot with the suction nozzle of bending only, particularly paste materials is bonded on the chamber wall easily, uses very easily.For example in hospital or medical cell culture experiment, be used to shovel and scrape the survivaling cell that is attached on the blake bottle wall, allow living cells split away off, shift the cultivation of going down to posterity then from blake bottle.Conventional method is could split away off the cultivation of then cell that splits away off being gone down to posterity to the living cells digestion that is attached on the blake bottle wall with digestive ferment.Owing to designed crooked suction nozzle, glass tube and blake bottle contact-making surface are increased, and head have certain angle, so can fully the living cells on each position that is grown in the Tissue Culture Flask can both shaving (shovel is scraped) be got off, adopt the elbow dropper in cell culture experiments, can save tradition and use the link of digestive ferment effect, save reagent, improve experiment stability, reduce repeatable operation, avoid polluting, easy and simple to handle, obviously increase work efficiency.
In addition, the utility model manufacture craft is simple, make on alcolhol burner easily as glass elbow dropper, and the Mold Making of plastic elbow dropper is also very simple, with low cost, and practical reference value is arranged.
Description of drawings
Fig. 1 is the schematic diagram of elbow dropper.
Fig. 2 is the enforcement structure chart of elbow dropper adsorbent solution in the blake bottle of solution is housed.
1-rubber sacculus glue head; 2-dropper main body; The 3-suction nozzle; 4-Tissue Culture Flask schematic diagram.
The specific embodiment
Further specify the enforcement structure below in conjunction with accompanying drawing:
With reference to accompanying drawing 1, the utility model is made of rubber sacculus glue head 1, dropper main body 2, crooked suction nozzle 3.With one in prior art glass dropper, after the thin end heating on the dropper main body, its bending that curves 80 °-150 ° is got final product, through facts have proved the stability and the operating efficiency that can effectively raise experiment.
With reference to accompanying drawing 2, in the blake bottle 4 that solution is housed, scrape the survivaling cell that is attached on bottle wall with crooked suction nozzle 3 shovels, allow living cells split away off from blake bottle, shift the cultivation of going down to posterity then, use very convenient.
Except the dropper main body of above-mentioned accompanying drawing was straight tube, laboratory main body commonly used was the dropper of fat tripe pipe, and suction nozzle 3 also can be made crooked shape.After suction nozzle 3 can be made bending separately, by glue pipe socket on dropper main body 2.
