Description

Environment-friendly highly efficient treatments of the sample device

Technical field

The utility model relates to a kind of chemical analysis instrument, specifically is a kind of environment-friendly highly efficient treatments of the sample device.

Background technology

In chemical analysis, sample (as fruit, vegetables, rice etc.) need carry out sour digest and decompose, changes solid sample into solution, carries out next step analytical test again.The employed digestion vessel in laboratory has digestion test tube, Kai Shi digestion bottle, conical flask, small beaker etc. at present.In real work, there is following problem: (1) digestion test tube, body is longer, for body can fully be heated, need to use special-purpose jack heater, because jack can't be observed the degree of treatments of the sample more deeply, often take place to measure the spent acid residual quantity after sample liquid is caused the phenomenon of the failure of an experiment or digestion to be finished by evaporate to dryness, the impact analysis result precision, in addition, because caliber is less, easy bumping was overflowed and is lost when treatments of the sample reacted violent, forced the minimizing sample weighting amount, had influenced Sensitivity of Analytical Method.(2) Kai Shi digests bottle, belongs to the long tube digestion vessel, adopts the heating of electric furnace or electric hot plate, needs the supporting use of special stand, and placement and transfer are inconvenient, and in addition, because the backflow effect of long tube need be adjusted to higher temperature during sample digestion, energy consumption is bigger.(3) conical flask or small beaker.All adopt the heating of electric furnace or electric hot plate, because the bottom area of container is flat and wide, can fully be digested for making sample, need to add more acid and soak sample, both consumed acid thus, increased the mensuration blank value again, the accuracy of impact analysis in addition, is caught up with quite trouble of acid, catch up with acid if uncap, sample solution is easy to be polluted by the environment dust, covered acid, the treatments of the sample overlong time (taking two days two nights sometimes) of catching up with, acid is residual too much, the impact analysis result precision.

The utility model content

The purpose of this utility model is to provide a kind of environment-friendly highly efficient treatments of the sample device at the deficiencies in the prior art, adopt the pyriform bottle to combine with spherical bottle cap, these problems that existed when having solved existing digestion vessel sample digestion, have sample weighting amount big, with acid less, recyclable acid solution, spent acid less residue, efficient height, deposit or effect such as conveniently moving.

The technical scheme that the utility model adopts:

A kind of environment-friendly highly efficient treatments of the sample device, formed by base, bottle and bottle cap, described base is flat annulus nested structure, bottle body bottom can be inserted in wherein, digester is placed on table top, pallet or heater reposefully, convenient title sample, digestion or movement simultaneously, adopt the annulus nested structure can make the bottle body bottom thermally equivalent; Described bottle is the pyriform structure, bottle body bottom is designed to cone, and sheathed connecting firmly on base, adopt the cone bottom that sample and acid solution are concentrated all the time to be immersed in the smaller size smaller space (even in digestion small amount of sample splash to the acid solution that is also refluxed on bottle wall wash back bottle and bore an end), example reaction is abundant, digestion thoroughly reaches the effect that digests big as far as possible sample weighting amount sample with minimum acid; Described bottle cap is made of the hollow glass ball that bottleneck covered, was arranged on the bottleneck side of covering, a steam vent is left in the side of the hollow glass ball of the bottleneck side of covering, ball is embedded in glass tube, the mouth of pipe of glass tube passes the bottleneck lid, when bottle cap covers the bottleneck of bottle, the mouth of pipe of glass tube communicates with bottle, utilizes both recyclable part acid of hollow glass ball, can avoid the environment dust to the pollution of sample again, improve accuracy and the degree of accuracy of analysis result.During use, take by weighing sample in bottle, add a certain amount of acid, screw the ground bottle cap, base is placed on electric hot plate or the electric furnace, first low-temperature heat, treat that sample decomposes digestion fully after, improve temperature again and drive spent acid, until a little acid amount of residue, take out cooling, shift constant volume, become solution to be measured.

The bottleneck of described bottle is interior ground or periphery ground, makes airtight cooperation of bottleneck ground of bottleneck lid with the bottle of bottle cap.

The utility model is simple in structure, easy to use, adopt the pyriform bottle to combine with spherical bottle cap, kinetic energy when effectively having slowed down the sample digestion vigorous reaction, avoid sample bumping ease to lose, both recyclable part acid, can avoid the environment dust to the pollution of sample again, can improve accuracy and the degree of accuracy of analysis result greatly, have sample weighting amount big, with acid less, recyclable acid solution, spent acid less residue, efficient height, deposit or effect such as conveniently moving, be applicable to the sample analysis that all need digest, the heat transfer efficiency height, save energy consumption, increase work efficiency.
