TECHNICAL FIELD
[0001] The utility model relates to chemical analysis field, concretely is a pipette gun adapter. BACKGROUND
[0002] In chemical analysis experiment, often need to accurately measure various organic solvents, such as halogenated hydrocarbon, ketone, aromatic hydrocarbon etc. Traditional pipetting tool is faced with different material and shape glass container and special nature's organic solvent, there is poor adaptability, the measurement precision is difficult to guarantee etc. Problem. For example, some pipette may be only applicable to specific specification or material glassware, it is extremely inconvenient when needing to switch different types of glass tube and measure operation, and for volatile, corrosive or sticky organic solvent, it is difficult to realize accurate and stable measurement process, which has a great influence on the accuracy and efficiency of chemical analysis experiment. SUMMARY
[0003] The utility model discloses a pipette gun adapter, to solve the limitation of the existing pipetting tool in the measurement of different glass tubes and organic solvents in chemical analysis experiment.
[0004] To achieve the above object, the utility model provides the following technical scheme: the utility model discloses adapter as the key connecting component, it is mainly by silica gel outer wall, sand core filter constitutes, silica gel outer wall has good flexibility and sealing property, it can be closely combined with the connecting part of micro pipettor and glass tube, effectively prevent liquid leakage.
[0005] The sand core filter is arranged in the middle of the adapter. The sand core filter can filter impurities, prevent the micro particles or impurities in the glass tube from being sucked into the micro pipettor during the pipetting process, and affect the accuracy and service life of the pipettor. At the same time, it also prevents the impurities from polluting the measured organic solvent, and ensures the accuracy of the experimental results.
[0006] The adapter internally reserves a cylindrical space with a certain diameter. This space design is to adapt to different specifications of micro pipettor and glass tube, so that a stable liquid transmission channel can be formed during connection, and the pipetting process can be smoothly carried out.
[0007] Compared with the prior art, the adapter has wide compatibility and can connect glass tubes of different materials. Whether it is common borosilicate glass tube or glass tube of other special materials, it can be well matched with the adapter. This feature allows flexible selection of glass tube materials according to different experimental requirements in chemical analysis experiments, without worrying about the compatibility of the pipetting tool. It can also connect glass tubes of various shapes, such as straight tubes, bent tubes, tapered tubes, etc. This adaptability to various shapes of glass tubes greatly expands the application range of the pipette in different experimental scenarios, improving the convenience of experimental operation. Through the cooperative work of the adapter, micro pipette and glass tube, halogenated hydrocarbon organic solvents can be accurately measured. Halogenated hydrocarbon organic solvents usually have volatility and certain corrosiveness. The special structure and material of the adapter can effectively cope with these characteristics, ensuring that the loss of organic solvents during measurement is minimized and the accuracy of pipetting is not affected. Similarly, for ketone organic solvents, which may have different viscosity and chemical activity, the adapter can also ensure that a stable liquid transfer system is formed with the micro pipette and glass tube during measurement, accurately measuring the required volume of ketone organic solvents. For aromatic hydrocarbon organic solvents, due to their special chemical structure and properties, such as the oxidation of some aromatic hydrocarbons, the adapter can prevent external factors from affecting them when connecting the micro pipette and glass tube, thereby achieving accurate measurement.
