Abstract

The utility model discloses a simple column chromatography case suitable for various chemical laboratories. The simple column chromatography case is provided with a case body, wherein two baffle plates are arranged in the middle of the case body to divide the case body into an upper chamber, a middle chamber and a lower chamber, the upper chamber is a sealed compression chamber, the lower chamber is a receiving chamber, bearing holes for bearing a chromatography column are correspondingly formed on the two baffle plates, and respectively provided with flexible sealing washers, a gas inlet is arranged on the door of the upper chamber, and a side door is assembled on the case wall at the front side of the lower chamber. By using the simple column chromatography case, the column pressure can be stable, and even though the instant compression is large, the spilling-out eluent can not hurt an experimenter due to the protection of the case body; besides, by adopting the case body, a plurality of columns can penetrate the case body simultaneously in the condition of only using one gas source, therefore, the experiment efficiency is improved, and the experimental equipment is saved.

Description

Simple and easy column chromatography case

Technical field

The utility model relates to a kind of chest, relates in particular to a kind of simple and easy column chromatography case.

Background technology

In order to raise the efficiency, save time the present pressing mode that mostly adopts when crossing pillar.Mainly contain two kinds of pressing mode at present: a kind of is directly to use the pressurizing ball pressurization, because pressurized systems is smaller, continuous minimizing along with eluant, eluent, the pressure of system is also constantly reducing in fact, and then adding eluant, eluent, that is to say that pillar is in during a kind of pressure changes all the time, the separation of composition is exerted an adverse impact.Another kind is to use inert gas, above pillar, use stopper, perforate inserts inert gas on the stopper, this mode can be so that pressure be more stable, and inert gas can also prevent that the sample in the pillar is rotten, but is easy to wash open stopper when instantaneous pressure is big, allow the eluent of pillar the inside spray, hurt the experimenter of pillar, and a source of the gas can only cross a pillar usually, if use Y-pipe separately also can cause branch gas inhomogeneous source of the gas.

The utility model content

The purpose of this utility model just is to provide a kind of simple and easy column chromatography case, can make the pillar pressure stability, can also prevent eluent injury experimenter and just can be simultaneously under the situation of only using a source of the gas too much root pillar, improved the efficient of testing.

To achieve these goals, the technical solution adopted in the utility model is such: simple and easy column chromatography case has a casing and last chamber door, this casing middle part has two dividing plates, this casing is divided into, in, following three Room, last chamber is the sealing compression chamber, following chamber is a receiving chamber, the all corresponding bearing hole that is used for the bearing chromatographic column that offers on two dividing plates, all is furnished with soft seal washer on each bearing hole, should go up the chamber door and be provided with air inlet, be equipped with side on the tank wall of front side, following chamber and open the door, can open the door by this side and put into or take out receiving bottle and switch chromatography column valve door.

As preferably: casing adopts transparent material to make, and makes things convenient for the laboratory technician to observe.

Compared with prior art, advantage of the present utility model is: adopting soft seal washer on the bearing hole is in order to keep air-tightness, is for better fixedly pillar and adopt two dividing plates.By using this column chromatography case can be so that the pressure stability when crossing pillar; because the protection of casing is arranged; even experimenter's moment pressurization when opening the inert gas valve is excessive; can or not make the eluent that spills injure the experimenter owing to the casing protection is arranged yet; be provided with a plurality of bearings hole in the case; in that just use under the situation of a source of the gas can simultaneously too much root pillar, improved conventional efficient.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment: referring to Fig. 1; simple and easy column chromatography case of the present utility model has a casing 5 and last chamber door 6; these casing 5 middle parts have two metal partion (metp)s 3; this casing 5 is divided into; in; following three Room; last chamber is the compression chamber; the compression chamber is in sealing state; following chamber is a receiving chamber; chromatographic column 2 is placed in the bearing hole 4 corresponding on two dividing plates 3; in order to increase air-tightness and the protection chromatographic column 2 of going up the chamber; all is furnished with soft seal washer on each bearing hole 4; should go up chamber door 6 and be provided with air inlet 7; air inlet 7 links to each other with the inert gas steel cylinder, has side on the tank wall of front side, following chamber and opens the door 8, can be by this side 8 valves of putting into or taking out receiving bottle 1 and switch chromatographic column 2 that open the door.

Casing 5 is made by transparent material, can make things convenient for the laboratory technician to observe.

In use, open chamber door 6 earlier, in the bearing hole 4 of correspondence, put into chromatographic column 2, insert silica gel and sample to be separated, add eluent, close and close chamber door 6, open the air inlet 7 that is connected with the inert gas steel cylinder, can begin pillar.

Simple and easy column chromatography case of the present utility model, not only can be so that the stable gas pressure of pillar, can also prevent effectively that eluent from spilling the injury experimenter, owing to be provided with a plurality of bearings hole 4 in the casing of the present utility model, too much root pillar can used under the situation of a source of the gas, improve conventional efficient, saved experiment equipment.
