Abstract
The utility model discloses an eddy evaporator for concentrating a small amount of liquid sample. By means of the eddy evaporator, a volatile solvent in the liquid sample in a sample bottle can be directly, fast and effectively removed, and the eddy evaporator is especially suitable for concentrating a small amount of liquid sample (less than 1mL). The eddy evaporator is composed of the sample bottle, a condensation recoverer, a vacuum pump and a water bath kettle. The sample bottle is covered with a rubber stopper with a thread. When the eddy evaporator is used, the liquid sample is placed into the sample bottle, the rubber stopper with the thread is screwed into the sample bottle tightly, the sample bottle is placed into the water bath kettle and is connected to the air inlet of the condensation recoverer through a first pipe, the vacuum pump is connected to the outlet of the condensation recoverer, a semi-closed communicating device is formed, the vacuum pump is started, and due to the fact a little amount of air is brought into the sample bottom through negative pressure, eddy stirring is produced, and therefore the purpose of removing the volatile solvent is achieved. According to the eddy evaporator, the sample is directly concentrated in the sample bottle, the operation steps are small, the operation method is simple, and the sample losses are low.
Description
Technical field
The utility model relates to that a kind of a small amount of fluid sample is concentrated uses whirlpool evaporimeter, belongs to laboratory apparatus technical field.
Background technology
It is one of significant element operation in chemical process that the fluid sample that contains volatile solvent concentrates, conventional solvent evaporation device is Rotary Evaporators at present, Rotary Evaporators is mainly used in a large amount of effumability solvents of continuous still under reduced pressure, in actual mechanical process, for a small amount of fluid sample (being less than 1mL) that contains volatile solvent, the common matching used rotary evaporation bottle of Rotary Evaporators is obviously excessive, in sample removal process, owing to sample will being recovered in sample bottle from rotary evaporation bottle, its operating procedure is many, method of operating difficulty, finally cause sample loss amount large.
Summary of the invention
In order to overcome the deficiency of above-mentioned technology, goal of the invention of the present utility model is to provide the whirlpool evaporimeter of the concentrated use of a kind of a small amount of fluid sample, utilize this device can directly in sample bottle, remove quickly and efficiently the volatile solvent in fluid sample, particularly, for the fluid sample (being less than 1mL) that is not suitable on a small quantity using Rotary Evaporators, this device can directly be removed the volatile solvent in sample bottle.
The utility model solves the technical scheme that its technical problem adopts: a kind of a small amount of fluid sample is concentrated to be comprised of sample bottle, condensation recovering device, vavuum pump and water-bath with whirlpool evaporimeter, on sample bottle, be stamped threaded plug, threaded plug is provided with pipeline one and is connected with condensation recovering device, and pipeline one is provided with valve A; On condensation recovering device, be also provided with pipeline two and be connected with vavuum pump, pipeline two is provided with valve B; During use, fluid sample is put into sample bottle, with threaded plug jam-pack, sample bottle is put into water-bath, sample bottle is connected to the gas access of condensation recovering device by pipeline one, vavuum pump is connected to the outlet of condensation recovering device, has formed a semienclosed communication apparatus, thereby open vavuum pump, because negative pressure drives, a small amount of air enters sample bottle and produces whirlpool and stir and reach the object of removing volatile solvent.
Described threaded plug and the surfaces externally and internally of pipeline one are equipped with anticorrosive coat.
The beneficial effects of the utility model are: owing to having designed threaded plug, when vavuum pump is opened, in sample bottle, produce negative pressure, make a small amount of air enter sample bottle and produce whirlpool from screw thread, fluid sample in the process of stirring by evaporate to dryness fast.The utility model can not used to revolve and steam bottle, does not use any stirring and whirligig, and sample is directly concentrated in sample bottle, and its operating procedure is few, and method of operating is simple, and sample loss amount is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Number in the figure:
1, sample bottle 2, condensation recovering device 3, vavuum pump 4, pipeline 1, threaded plug
6, water-bath 7, valve A 8, valve B 9, pipeline two.
The specific embodiment
Example
As shown in Figure 1, this device is comprised of with water-bath 6 sample bottle 1, condensation recovering device 2, vavuum pump 3, is stamped threaded plug 5 on sample bottle 1, and threaded plug 5 is provided with pipeline 1 and is connected with condensation recovering device 2, and pipeline 1 is provided with valve A 7; On condensation recovering device 2, be also provided with pipeline 29 and be connected with vavuum pump 3, pipeline 29 is provided with valve B 8; During use, fluid sample is put into sample bottle 1, with threaded plug 5 jam-packs, sample bottle 1 is put into water-bath 6, sample bottle 1 is connected to the gas access of condensation recovering device 2 by pipeline 1, vavuum pump 3 is connected to the outlet of condensation recovering device 2, has formed a semienclosed communication apparatus, thereby open vavuum pump 3, because negative pressure drives, a small amount of air enters sample bottle 1 and produces whirlpool and stir and reach the object of removing volatile solvent.
