Abstract
The utility model discloses a novel chromatographic device which comprises a chromatographic pillar (1) and a collection bottle (2), wherein the collection bottle (2) is provided with two openings, one opening is connected with the lower end of the chromatographic pillar (1), and the other opening is connected with a ground opening of a connecting pipe (3); a ground opening at the other end of the connecting pipe (3) is connected with a rotary evaporator (5); a pipette (4) is arranged in the connecting pipe (3); and the lower half part of the collection bottle (2) is immersed in a mixed ice-water bath kettle (7), thus being capable of realizing separation and concentration recovery of mixture in a relatively closed pipeline, reducing contact between easily decomposable substance and air, being capable of preventing decomposition of easily decomposable substance, and guaranteeing the separation effect, in addition, being capable of preventing volatilization of toxic organic solvent, reducing loss of the solvent, preventing environment pollution simultaneously and guaranteeing health of operators. The novel chromatographic device has novel structure, is beneficial to protecting environment and is simple and practical.
Description
Technical field
The utility model relates to a kind of chemical experiment equipment, relates in particular to a kind of unstable material separation, eco-friendly novel chromatographic apparatus of being used for.
Background technology
Chromatographic technique be a kind of according to different material in different medium physics, chemistry or biological property difference and the migration velocity difference, thereby realize the technology of the separation and purification of material now has been widely used in industries such as chemical industry, food, medicine.Chromatographic column is one of a kind of separation equipment the most frequently used in the chromatography process.Common chromatographic column can be divided into normal pressure post, middle compression leg and high-pressure column according to the pressure difference.The normal pressure post is with the most use in practice, usually is the chromatographic column that oneself adopts different materials as required, the separation and purification that the different filler of filling is realized target substance.Glass chromatography column is especially commonly used again, often comprises cylinder, piston, is positioned at also comprising of having the barb that is used for fixing the liquid feeding ball of cylinder upper end etc.
There is following deficiency in common glass chromatography column device at present: owing to usually being separates and concentrate to reclaim to divide to cover row, for character instability, labile material, usually owing to the long period ingress of air, perhaps environment temperature is higher, can decompose.And, the easy more decomposition of the material that normally biologically active is high more, purity is high more.In addition, separation solvent commonly used all is poisonous organic solvent, and long term exposure is easily lost because of volatilization in air on the one hand, and operator's health is threatened also influences environment on the other hand.
The utility model content
The purpose of this utility model just be to provide a kind of address the above problem can collect and reclaim, be easy to prevent substance decomposition simultaneously and the operator is healthy and eco-friendly novel chromatographic apparatus.
To achieve these goals, the technical solution adopted in the utility model is such: comprise chromatographic column and the receiving flask that is connected with chromatographic column lower end ground, described receiving flask is two mouthfuls of receiving flasks, be connected with the chromatographic column lower end flatly, another mouthful is connected with the tube connector ground, and the other end ground of described tube connector is connected with a Rotary Evaporators, is provided with a pipette in the tube connector, described pipette one end stretches into receiving flask, and the other end stretches into the evaporative flask upper end of Rotary Evaporators.
As preferably: described receiving flask Lower Half is dipped in frozen water mixing water bath.
Compared with prior art, advantage of the present utility model is: because each junction adopts ground to connect, can in the pipeline of a relative closure, realize the separation of mixture and concentrate reclaiming, reduce contacting of easy decomposed substance and air, and below receiving flask, be placed on frozen water mixing water bath, can prevent the decomposition of easy decomposed substance, guarantee separating effect, in addition, can prevent poisonous organic solvent volatilization, prevent the pollution of the environment when reducing solvent loss, and guarantee operator's health, the utility model novel structure is beneficial to environmental protection, and is simple and practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
Referring to Fig. 1, comprise chromatographic column 1 and the receiving flask 2 that is connected with chromatographic column 1 lower end ground, receiving flask 2 is two mouthfuls of receiving flasks, be connected with chromatographic column 1 lower end flatly, another mouthful is connected with tube connector 3 grounds, and the other end ground of tube connector 3 is connected with a Rotary Evaporators 5, be provided with a pipette 4 in the tube connector 3, pipette 4 one ends stretch into receiving flask 2, and the other end stretches into evaporative flask 6 upper ends of Rotary Evaporators 5, and receiving flask 2 Lower Halves are dipped in frozen water mixing water bath 7.
During use, flow point after the chromatography enters receiving flask 2, liquid in receiving flask 2 reaches certain amount, when perhaps being a certain one-component, can start Rotary Evaporators, because pressure differential, the liquid in the receiving flask 2 enters the evaporative flask of Rotary Evaporators 5 by pipette 4, realizes the concentrated recovery to liquid; Because each junction adopts ground to connect, can in the pipeline of a relative closure, realize the separation of mixture and concentrate reclaiming, reduce contacting of easy decomposed substance and air, and below receiving flask 2, be placed on the frozen water mixing water bath 7, can prevent the decomposition of easy decomposed substance, guarantee separating effect, the utility model novel structure, simple and practical.
Claims (2)
1. novel chromatographic apparatus, comprise chromatographic column (1) and the receiving flask (2) that is connected with chromatographic column lower end ground, it is characterized in that: described receiving flask (2) is two mouthfuls of receiving flasks, be connected with chromatographic column (1) lower end flatly, another mouthful is connected with tube connector (3) ground, the other end ground of described tube connector (3) is connected with a Rotary Evaporators (5), be provided with a pipette (4) in the tube connector (3), described pipette (4) one ends stretch into receiving flask (2), and the other end stretches into evaporative flask (6) upper end of Rotary Evaporators (5).
