Abstract
This utility model involves a titration removing liquid instrument, especially refers to a drop bottle usually using in comparatively accurate liquid extraction, which may solve problem of many plastic parts and can not use for volatile or the corrosive liquid transferring by the present expensive ration moving liquid guns. The technical plan is: This quantitative drop bottle comprises a capacity bottle and a liquid moving device. The moving liquid device is fixed on capacity bottle. The liquid moving device has a syringe. The external diameter of the syringe is smaller than the diameter of the bottle bottleneck. The tube body has scales. The connection between the wall of the syringe and bottleneck applies the method of seal connections. A free pushing rod is arranged in the syringe tube body. The pushing rod top and syringe top are all connected with regular fixing parts. The syringe top has a spring which positioned between the syringe entrance and boss of pushing rod end. One end of sliding rod is arranged on the horizontal extension of syringe fixing parts. The other end passes through the horizontal extension of pushing rod fixing parts. The upper end of sliding rod is connected with the slip bar which can slip alone the sliding rod. The flank of slip bar is arranged the fixing screw. This utility unit mainly applies in the transferring volatile or the corrosive liquid.
Description
Technical field: the utility model relates to a kind of titration liquid-transfering device, is meant a kind of drop bottle that is applied in often and uses will draw certain amount of fluid comparatively accurately the time especially, and this liquid may have volatility and corrosivity, and needs airtight preservation.Especially be applied in to do and draw deuterated reagent in the nmr analysis.
Background technology:
In the structure authentication method of compound, nmr analysis is a kind of comparatively common method.It need be dissolved in compound in the middle of the deuterated reagent, the amount of each used deuterated reagent is probably about 0.6ml, the price comparison costliness of deuterated reagent, the researcher adds solvent with common Dropping bottle with rubble cap generally speaking, but because consumption seldom, and the nuclear-magnetism pipe is very thin, be difficult to the control addition, during most operation all is to add excessive deuterated reagent, in order to add deuterated reagent less, the researcher can only cautious adding reagent, therefore greatly reduces operating efficiency.When the chemical experiment of doing other and analysis experiment, also often need quantitatively pipette certain amount of fluid reagent simultaneously.The at present general quantitative liquid-transfering gun that uses costs an arm and a leg, and inside has a lot of plastic components, can not be used for volatility or corrosive reagent pipettes.Therefore need a kind of simple structure, low price and can be used to volatilize and the quantitative drop bottle of corrosive liquids.
Summary of the invention:
The purpose of this utility model provides a kind of drop bottle of quantitative imbitition.Solve existing quantitative liquid-transfering gun, cost an arm and a leg, and inside has a lot of plastic components, can not be used for the technical problem that volatility or corrosive reagent pipette.The technical solution of the utility model is: this quantitative drop bottle comprises that volumetric flask and liquid-transfering device constitute, and liquid-transfering device is fixed on the volumetric flask.
Liquid-transfering device includes syringe, and the external diameter of this syringe is less than the volumetric flask bottleneck diameter, and stack shell has scale, and syringe outer wall and volumetric flask bottleneck are tightly connected.The push rod that can be free to slide in stack shell is arranged in the syringe, push rod top and syringe top all are socketed with fixture, push rod top is socketed with spring, Spring Card is connected between syringe inlet and the push rod head boss, slide bar one end is fixed on the horizontal-extending end of syringe fixture, the other end of slide bar passes the horizontal-extending end of push rod fixture, and the upper end of slide bar is socketed with can be along the slide block of slide bar slip, and the side of slide block is provided with holding screw.
This device following advantage of tool in the process of using: the first, can when doing experiment, draw certain amount of fluid reagent comparatively accurately.The second, increase work efficiency, reduce the consumption of reagent, save cost.The 3rd, simple structure, inner no plastics or lubricating component can pipette volatilization or corrosive liquid.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
Among the figure: 1-slide block, 2-push rod fixture, 3-spring, 4-slide bar, 5-syringe securing member, 6-push rod, 7-syringe, 8-volumetric flask.
The specific embodiment: with reference to accompanying drawing, quantitatively drop bottle comprises that volumetric flask and liquid-transfering device constitute, and liquid-transfering device is fixed on the volumetric flask.Volumetric flask 8 is a port grinding bottle, and liquid-transfering device includes the syringe 7 of stack shell band ground, and the ground and the port grinding bottle of this syringe are complementary, and stack shell has scale.The push rod 6 that can be free to slide in stack shell is arranged in the syringe, push rod top and syringe top all are socketed with fixture, push rod top is socketed with spring 3, spring 3 is connected between syringe inlet and the push rod head boss, slide bar one end is fixed on the horizontal-extending end of syringe fixture 5, the other end of slide bar passes the horizontal-extending end of push rod fixture 2, and the upper end of slide bar is socketed with can be along the slide block 1 of slide bar slip, and the side of slide block 1 is provided with holding screw.When screw tightening, slide block 1 just can be fixed on certain position of slide bar 4, and slide block can be used for regulating the height that push rod 6 is pressed, and therefore can control the volume of imbitition.
This device is easy to use, processing ease.Before use, take out liquid-transfering device earlier, volume as required by to needed scale, is tightened the screw of slide block 1 side to push rod 6, makes push rod 6 be fixed on a certain scale, so just can draw certain amount of fluid.
Claims (2)
1, a kind of quantitative drop bottle, it is characterized in that comprising volumetric flask and liquid-transfering device structure, liquid-transfering device is fixed on the volumetric flask, liquid-transfering device includes syringe, the external diameter of this syringe is less than the volumetric flask bottleneck diameter, stack shell has scale, syringe outer wall and volumetric flask bottleneck are tightly connected, the push rod that can be free to slide in stack shell is arranged in the syringe, and push rod top and syringe top all are socketed with fixture, and push rod top is socketed with spring, slide bar one end is fixed on the horizontal-extending end of syringe fixture, the other end of slide bar passes the horizontal-extending end of push rod fixture, and the upper end of slide bar is socketed with can be along the slide block of slide bar slip, and the side of slide block is provided with holding screw.
