Embodiment

The utility model will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the overall structure diagram of the utility model extractive reaction device；Fig. 2 fills for the utility model extractive reaction The exploded perspective view put.

Fig. 1 and Fig. 2 are referred to, the extractive reaction device that the present embodiment provides includes reaction bulb 3, and the port of reaction bulb 3 is set Lid 1 is equipped with, upper lid 1 is preferably aluminium lid, and upper lid 1 can be sealed by jaw with reaction bulb 3 and screwed, and aluminium lid jaw can provide non- Often closely sealing, reduce sample and the possibility of reagent volatilization；Sealing dottle pin 2 is provided with upper lid 1, dottle pin material is silicon Glue/PTFE, silica gel/PTFE strands display is intensive, limits the heat activity of polymer molecule, thus air penetrability is low, air-tightness It is good, both possessed excellent corrosion-resistant, high temperature resistant, nontoxic, resistance to bond, and there is good elasticity and sealing again, it is not easy to change Learn reagent to react, property is stable；Reaction bulb 3 is using high-boron-silicon glass conductive characteristic at high operating temperatures, by glass Heated inside glass to realize glass melting, borosilicate glass has low-down thermal coefficient of expansion, is approximately the three of simple glass / mono-.This will be reduced influences caused by thermograde stress, so that there is stronger break resistance, wall thickness 1.0 ± 0.05mm, pipe thickness is uniform, can carry out high speed centrifugation.Principle of negative pressure is utilized simultaneously, forms the bottom with needle tubing shape, i.e., The bottom of reaction bulb 3 is connected formed with pin tube-shaped through hole 5, pin tube-shaped through hole 5 with Luer plug 6 or negative-pressure container, and Rule is blocked up First 6 be that the micro nothing of standardization oozes joint, is made of medical grade polypropylene (pp) virgin material, the transparent acid and alkali-resistance of intrinsic colour, resistance to Dissolving, high temperature resistant；The bottom of reaction bulb 3 is additionally provided with sieve plate 4；The material of sieve plate 4 is polyethylene, adapts to 40mL glass Bottle, is resistant to soda acid and most organic solvent.When extractive reaction is completed, Luer plug 6, pin tubular base 5 can be removed External connecting negative pressure container, negative-pressure container top are connected with aspiration pump, coutroi velocity, extract are filtered out.
