Description
Technical field
The present invention relates to a kind of drying and filtering integral device, behind especially a kind of liquid-liquid extraction, the integrated apparatus of organic extract liquid dry filter.
Background technology
In chemical analysis; Liquid-liquid extraction is one of the most frequently used abstraction technique of fluid sample; It is the solvent that in liquid mixture, adds with its not miscible (or miscible slightly), utilizes the difference of its component solubility in different solvents and reaches the purpose of separating or extracting.In the process of extraction, some water meeting diffusion transfers are always arranged in solvent, therefore, for ease of follow-up analysis (like gas chromatographic analysis), extract just need dehydrate processing.Because the liquid mixture component is complicated, and in the extraction process, some impurity may get into extract, when therefore carrying out organic analysis, also need filter simultaneously extract.Conventional way is earlier extract to be dehydrated, and then filters again, filtrating is transferred in the cucurbit to concentrate at last.In the extract transfer process, have a spot of loss, and the number of times that shifts is many more, final loss also can be obvious more.In that to carry out some required precisions high, during the less again experiment of extract, tend to because these are former thereby influence experimental result.The repeatedly transfer of extract not only pollutes the environment, and has increased labour intensity and to operating personnel's murder by poisoning, but also in transfer process, has also increased the contaminated possibility of material.
For the filtration of extract, suction filtration and press filtration dual mode are arranged usually.Suction filtration is a negative pressure, how to carry out with vavuum pump, if boiling point substance is lower, then suction filtration is prone to cause the loss of material.Press filtration is a malleation, can adopt air compressor machine or inert gas to increase pressure, adopts the press filtration meeting to reduce loss for low-boiling point material, if material is responsive to air ratio, generally adopts the inert gas press filtration.These two kinds of filter types need adopt different devices to accomplish usually, and cost is higher.
Summary of the invention

Said sintering filter top is the plain grinding mouth, and outer rim is as flange, and the bottom is the outer frosted mouth of standard, and sintering filter one side is provided with the ventilation mouth, can carry out the suction filtration operation to device through it.
Said receiving bottle is a frosted mouth in the standard.
Said clip material is a stainless steel, can dry packed column, filter membrane and sintering filter be linked through it
Said except that loam cake, glass core, filter membrane and clip, the remainder material is the high-quality borosilicate glass.
3. beneficial effect
The invention provides a kind of drying and filtering integral device for organic extract liquid, drying and filter process that can disposable completion organic extract liquid, and can select press filtration or suction filtration according to the character of solvent; Filtrating can directly concentrate on Rotary Evaporators, need not shift, and greatly reduces the loss amount of sample; Certainty of measurement is high; Simple to operation, save and hold agent, can also reduce the murder by poisoning of sample treatment to second environmental pollution and operating personnel.
