Description
Technical field
The present invention relates to a kind of flared method, the flared method sealing lid of the pressure used during a kind of micro-wave digestion.
Background technology
Microwave dissolver is configured with pressure, is used for holding sample and digestion solution.The obturating cup covered by sealing when pressure uses realizes airtight, to produce the effect of airtight supercharging when micro-wave digestion, i.e. sample and digestion solution is heated by the quick of microwave in hermetic container, make sample at high temperature under high pressure, surface layer stirs, ruptures, constantly produce new specimen surface to contact with solution, until sample digestion is complete.
The existing big multiplex politef of lid that seals is made, and under the conditions of micro-wave digestion, the shirt rim of obturating cup can deform.Therefore, as it is shown in figure 1, general microwave dissolver can be furnished with mouth expander 20 ', before every use, directly with mouth expander 20 ' to obturating cup 12 ' enlarging.But, seal after lid 10 ' uses for a long time, this direct flared method has been unable to reach preferable enlarging effect, it is impossible to solve the problem on deformation of obturating cup, and when causing micro-wave digestion, the pressure in container does not reaches requirement, and Specimen eliminating is incomplete；And after the deformation of obturating cup shirt rim, directly result in counteracting tank gas leakage, under High Temperature High Pressure effect, there is splash, molten tank phenomenon；May result in counteracting tank framework when expulsion events is serious to dissolve；Strong acid steam brings potential safety hazard to experimenter.
Summary of the invention
It is an object of the invention to provide the flared method sealing lid in a kind of microwave dissolver, the sizing that seal lid can be better achieved, it is to avoid sealing lid in use leaks gas, expulsion events.
The invention provides the flared method sealing lid in a kind of microwave dissolver, including: a, the obturating cup sealing lid is moistened, and be filled with water in making obturating cup；B, mouth expander is inserted fill the obturating cup of water；C, the sealing lid with mouth expander is placed in baking oven, it is to avoid the water in obturating cup flows out, toasts 6 to 8 hours at 98 to 102 DEG C；Take out from baking oven again and cool down at least 18 hours；And d, mouth expander is covered from sealing and takes off.
In sealing the another kind of exemplary embodiment of flared method of lid, the material sealing lid is politef.
In sealing another exemplary embodiment of flared method of lid, by the method that obturating cup is moistening it is: sealing lid pure water is cleaned or soaks.
In sealing a kind of exemplary embodiment of flared method of lid, the action that mouth expander inserts obturating cup is carried out in water.
In sealing a kind of exemplary embodiment of flared method of lid, also include, mouth expander is covered from sealing after taking off, sealing lid is vertically mounted in pressure, stand no less than 72 hours.The sealing lid after enlarging and pressure can be made the most closely sealed, reach more preferable fixed effect.
The microwave dissolver that the present invention provides seals the flared method of lid, preferably achieves the sizing sealing lid, it is possible to decrease seal the danger that lid in use brings to experimenter because of gas leakage, splash.When covering in the face of nonexpondable sealing, common direct flared method cannot realize enlarging sizing, and the flared method sealing lid of the present invention by the recovery of deformable seal lid shirt rim extremely close to new product, and can be able to be used for multiple times after an enlarging.
