Abstract

The invention belongs to the field of sealing, and particularly relates to an ampoule bottle low-temperature heat-sealing method which comprises the following steps: carrying out heat-sealing on an ampoule bottle filled with a standard solution prepared from a low-boiling-point solvent at the temperature of lower than 15 DEG C which is provided by a low-temperature heat-sealing device, the low-temperature heat-sealing devicecomprises a flame nozzle and a rotating motor, the low-temperature heat-sealing device also comprises a brass sleeve, whereina cavity matched with the ampoule bottle in shape is formed in the brass sleeve, the brass sleeve is sleeved with a red copper sleeve, a semiconductor chilling plate is connected to the outer side of the red copper sleeve, an aluminum heat dissipation plate is connected to the outer side of the semiconductor chilling plate, an exhaust fan is connected to the outer side of the aluminum heat dissipation plate, and the red copper sleeve, the semiconductor chilling plate, the aluminum heat dissipation plate and the exhaust fan are arranged on a support. A rotating motor is hung on the support, and a rotating rod of the rotating motor is connected with the brass sleeve. The invention provides the heat-sealing method for the standard solution prepared from the low-boiling-point solvent, so that volatilization of the solvent caused by sealingunder a high-temperature condition and change of other properties of the standard solution at high temperature are avoided, and other properties such as accuracy of the standard solution are ensured.

Description

technical field [0001] The invention belongs to the field of sealing, in particular to a method for low-temperature melting and sealing of ampoules. Background technique [0002] Ampoule is a sealed glass vial with a capacity of 1-25mL, commonly used to store standard solutions of solvents, etc. After the ampoule is filled with the standard solution, the ampoule is usually sealed by hot-melting, and the glass at the mouth of the ampoule is melted and sealed by the high temperature generated by the combustion. The standard solvent sealed and melted by this method is easily volatilized due to the high temperature of the flame, especially for the standard solution prepared with a low boiling point solvent, which affects the quality, concentration and other properties of the standard solution in the bottle. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned technical problems, the present invention provides a method for low-temperature melting and sealing of amp...
