Abstract
The utility model discloses a device for metering the amount of added liquid through nitrogen filling and oxygen dispensing, which is characterized by comprising a sunk-bottomed glass bottle (1), an extraction apparatus (9), a nitrogen cylinder (12) and a nitrogen conveying pipe (10), wherein the sunk-bottomed glass bottle (1) is provided with a scale (2), the extraction apparatus (9) is inserted in the glass bottle, vent holes (11) are fully distributed at one end of the nitrogen conveying pipe (10), the upper end of the extraction apparatus (9) is provided with a pressure head (6) and a spray pipe (5), the middle section of the extraction apparatus (9) is sleeved with a bottle cap (7) of the glass bottle (1), a scale (4) is engraved on the outside of a pipe between the bottle cap and the pressure head, and the upper top surface of the glass bottle is provided with a nitrogen conveying pipe through hole (8) and an oxygen and nitrogen discharge hole (3). The device relates to a chemical experimental apparatus, and specially used for carrying out nitrogen filling and oxygen dispensing on liquid and metering the amount of added liquid; the device is simple in structure and wide in applicability; and nitrogen filling and oxygen dispensing can improve the accuracy of experiments, and through a pressing operation, the amount of added liquid can be known by observing the two scales. A sunk bottom of the glass bottle facilitates that a straw absorbs a liquid in the bottle, thereby saving the cost.
Description
Technical field
The present invention is a kind of chemical experimental instrument, specifically with the liquid addition metering device of oxygenation Qu Dan mechanism.
Background technology
In the related experiment of Study on Protein, often can add liquid to adjust pH of cushioning fluid.At present, trace or marginally add liquid, by liquid-transfering gun, realize, but add liquid in a large number, can only lean on graduated cylinder or buret to determine, this kind of method accessory is many, complicated operation, experimental period is long, and easily contaminated.In configuration buffer solution process, the oxygen peak that the oxygen in solution produces conventionally can produce certain impact to subsequent experimental result.So far, not yet finding that there is the relevant chemical experimental instrument that overcomes above-mentioned deficiency exists formerly open.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of nitrogen that fills and drives oxygen liquid addition metering device.
Addressing the above problem adopted technical scheme is: originally fill nitrogen and drive oxygen liquid addition metering device, comprise concave bottom vial with scale, be inserted in the nitrogen feeding pipe that extractor, nitrogen cylinder and one end in this bottle is covered with venthole, there are pressure head and jet pipe in described extractor upper end, stage casing cover has the bottle cap of vial, pipe between bottle cap and pressure head is carved with scale outward, has nitrogen feeding pipe through hole and deoxygenation nitrogen hole on the upper end face of vial.
The beneficial effects of the utility model are: by logical nitrogen, drive oxygen, avoided the interference of oxygen peak in solution testing result coordinate diagram, improved the accuracy of experiment; The concave bottom of vial, liquid at the bottom of favourable suction pipe draws bottle, does not waste: by pressing operation, observing two kinds of scales is known added amount of liquid, both can add soon, also can drip, and has expanded the applicability of device.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
The specific embodiment
The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: referring to accompanying drawing, originally fill nitrogen and drive oxygen liquid addition metering device, comprise concave bottom vial 1 with scale 2, be inserted in the nitrogen feeding pipe 10 that extractor 9, nitrogen cylinder 12 and one end in this bottle is covered with venthole 11, there are pressure head 6 and jet pipe 5 in described extractor 9 upper ends, stage casing cover has the bottle cap 7 of vial 1, pipe between bottle cap and pressure head is carved with scale 4 outward, has nitrogen feeding pipe through hole 8 and deoxygenation nitrogen hole 3 on the upper end face of vial.
During use, first twist-off closure 7, after taking out together with extractor 9, in vial, add solution, again extractor is reinserted in this bottle, tightens bottle cap, by nitrogen feeding pipe 10 with one end of venthole 11 through nitrogen feeding pipe through hole 8 straight cuttings the concave bottom place to vial 1, another termination nitrogen cylinder 12, then pass into nitrogen in this bottle.If need to add in a large number this solution, logical nitrogen after a few minutes the oxygen in solution can be displaced completely, constantly pass into nitrogen, make to maintain an atmospheric air pressure in vial, so that solution extrudes.With the scale 2 on vial, judge the amount of added solution.First writing down scale is a, and by head 6 suddenly, solution, from jet pipe 5 ejections, adds solution to adjust pH in buffer solution, after being transferred to required pH value, writes down scale b now, and calculating a-b, knows amount of solution used.If only need add on a small quantity this solution, flicking head 6, just can drip solution.Structure and the inflator of the extractor in this liquid addition metering device are similar, the check valve of upper and lower a pair of opposite direction, by first time head, in solution suction line, by second time head, in pipe, solution is just from jet pipe 5 ejections, jerk just spray, flicking just drips, the amount of its interpolation, the reading from the scale 2 of vial of large quantity, the reading from the scale 4 of extractor of smallest number.
Claims (1)
1. one kind is filled nitrogen and drives oxygen liquid addition metering device, it is characterized in that comprising band scale (2) concave bottom vial (1), be inserted in the nitrogen feeding pipe (10) that extractor (9), nitrogen cylinder (12) and one end in this bottle is covered with venthole (11), there are pressure head (6) and jet pipe (5) in described extractor (9) upper end, stage casing cover has the bottle cap (7) of vial (1), pipe between bottle cap and pressure head is carved with scale (4) outward, has nitrogen feeding pipe through hole (8) and deoxygenation nitrogen hole (3) on the upper end face of vial.
