Description
[technical field]
The utility model relates to laboratory accessory appliances, specifically a kind of bottle cap for liquid chromatography solvents bottle.
[background technology]
Existing traditional liquid chromatograph mobile phase bottle used adopts on bottle cap perforate on perforate or inner casing cover, and number of aperture is generally 2-4.Except the hole that mobile phase pipeline accounts for, remaining hole directly communicates with air, easily make dust fall into or be climbed into by small worm, easily cause mobile phase in bottle by the pollutions such as dust in external environment, when serious, can cause the obstruction of mobile phase pipeline filtering head and chromatographic instrument associated components, in the service life that shortens instrument, affect experimental result; Organic facies in mobile phase bottle can be volatilized in the perforate on bottle cap simultaneously, waste solvent, pollute experimental situation simultaneously, experimenter's respiratory tract and mucosal sites etc. are produced to potential harm, and gases such as carbon dioxide and oxygen in bottle also easily react with the generation of mobile phase liquid, thereby cause the chromatogram character of mobile phase to change, and then affect experimental result.
In recent years, along with the development of liquid chromatogram (LC) corollary equipment, famous consumptive material company of several families has released brand-new solvent bottle in the world, on bottle cap, has designed general 1/8 " hydraulic pipe jointing; solved to a certain extent sealing problem, but but exist following contradiction.If sealed solvent bottleneck, though can thoroughly prevent volatile liquid volatilization, can just easily cause a bottle interior negative pressure once solvent is exported, causes solvent cutout, impact analysis effect greatly because infusion pump suction is not enough completely.
[summary of the invention]
The utility model is in order to solve the existing above-mentioned deficiency of prior art, a kind of cover of dust of mobile phase bottle in liquid chromatography is provided, it can overcome in prior art external environment flow, and to pollute mutually probability larger, experimental situation is polluted in mobile phase organic solvent volatilization, and the some shortcomings that easily change of the chromatogram character of mobile phase.
To achieve these goals, the utility model provides a kind of bottle cap for mobile phase bottle in liquid chromatography, bottle cap is provided with mobile phase pipeline hole and air extractor vent, in described bottle cap, be provided with inner cap, on the outside face relative position of the inside face of bottle cap and inner cap, be equipped with positioning teeth, bottle cap and inner cap are connected with a joggle by positioning teeth, on the upper surface of inner cap, offer and mobile phase perforate and ventilation opening that on bottle cap, mobile phase pipeline hole and air extractor vent are corresponding, in described ventilation opening, there is inside hole wall, on hole wall, cover air filter film, in bottle cap top surface edge, be fixed with a blowout patche, blowout patche is connected with a stopple by cord, stopple matches with described mobile phase pipeline hole and air extractor vent, on described stopple, cover has seal ring.
Said structure also further has following design:
The material of stopple is preferably polytetrafluoroethylene.
Described lid top is preferably provided with three mobile phase pipeline holes and an air extractor vent.
The bottle cap of mobile phase bottle in liquid chromatography of the present utility model, owing to being provided with air filter film and stopple in the ventilation opening of inner cap, by opening and closure of stopper, realized mobile phase bottle in liquid chromatography and extraneous being communicated with closed, can keep in use inner and outer air pressure consistent, avoid because negative pressure in bottle causes mobile phase cutout, guarantee analytical effect, go back actv. simultaneously and reduce solvent evaporates, dust falls in bottle, stop small worm to climb into, postpone the instrument life-span.

[specific embodiment]
Below by specific embodiment, the utility model is described further, following embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, bottle cap for mobile phase bottle in liquid chromatography is provided with three mobile phase pipeline holes and an air extractor vent, in bottle cap top surface edge, be fixed with a blowout patche, blowout patche is connected with a stopple by cord, the quantity of stopple can increase and decrease according to demand, and the material of stopple is preferably polytetrafluoroethylene, and stopple matches with described mobile phase pipeline hole and air extractor vent, on described stopple, cover has seal ring, and seal ring increases the leak tightness of stopple and lid.
As shown in Figure 2, in described bottle cap, be provided with inner cap, on the outside face relative position of the inside face of bottle cap and inner cap, be equipped with positioning teeth, bottle cap and inner cap are connected with a joggle by positioning teeth, on the upper surface of inner cap, offer and mobile phase perforate and ventilation opening that on bottle cap, mobile phase pipeline hole and air extractor vent are corresponding, in described ventilation opening, there is inside hole wall, on hole wall, cover air filter film.
Mobile phase pipeline hole is used for inserting mobile phase pipeline, no mobile phase pipeline hole available backup stopple (not shown) clogs, prevent that dust from falling into or small worm climbs into and mobile phase volatilization, air extractor vent is closed with stopple when instrument cuts out, and during work, opens.
To sum up, the utility model simplicity of design, has solved the phenomenon of mobile phase volatilization, contamination by dust and the solvent cutout of traditional liquid phase Mobile-phase reagent bottle bottle cap existence.
