Abstract
The utility model discloses a large-bore glass chromatographic column bracket. The bracket is vertically arranged on a base, and a fixing plate is arranged on the bracket. The bracket is characterized in that the fixing plate and the bracket are arranged in a manner as follows: the middles of the bracket and the fixing plate are connected and fixed by middle bolts and nuts, an elastic clamping hoop is respectively arranged at the upper part and the lower part of the fixing plate, and a supporting plate is arranged at the lower part of the fixing plate. According to an optimum scheme, the bracket and the inner sides of the clamping hoops are provided with silica gel pads, the top end of the fixing plate is provided with an upper positioning clamping slot, the bottom end of the fixing plate is provided with a lower positioning clamping slot, the top end of the bracket is provided with a positioning bolt corresponding to the positioning clamping slots, and a chromatographic column can be kept vertical and be opened at the upper part and inclined downwards by a 45-degree angle by respectively using the positioning bolt and one poisoning clamping slot as well as the positioning bolt and the other poisoning clamping slot, namely, an eluting mode and a cleaning mode. According to the bracket, the large-bore glass chromatographic column can be installed and fixed conveniently and well, the operations of material loading in chromatographic separation ahead of an experiment, material unloading and airing after the experiment and the like can be conveniently simplified, and the bracket is simple in structure, low in manufacturing cost and easy to popularize and use.
Description
Technical field
The utility model relates to a kind of laboratory equipment, is specifically related to a kind of heavy caliber glass chromatography column support.
Background technology
Chromatography is the synthetic middle mode commonly used of purifying of separating of present bulk drug, intermediate; Increase along with product consumption; The disposal ability of chromatographic column and the volume of chromatographic column are also in continuous increase; Operation has brought inconvenience to chromatography, and the amplification that has restricted the chromatography technology is used, and the popularization of heavy caliber glass chromatography column.Mostly present widely used heavy caliber chromatographic column is stainless steel, convenient pressurization, and through pressure or vacuum mode charging and discharging, this device technique requires high, and the product cost is high, and situation is not directly perceived in the chromatographic column, and affected complicacy is difficult to batch duplicating.If the heavy caliber chromatographic column that adopts glass to make then exists the frangible deficiency of glassware, particularly heavy caliber glass chromatography column to be difficult on the column holder install and fix analysing of prior art, bring a lot of inconvenience for experimenter's operation.
Summary of the invention
The purpose of the utility model is the deficiency that exists in the chromatography equipment in order to improve; A kind of simple heavy caliber glass chromatography column support is provided; This heavy caliber glass chromatography column support can install and fix bigbore glass chromatography column easily, and has conveniently simplified before the experiment charging in the chromatography, experiment back discharging and operation such as dried.This apparatus structure is simple, and cheap being easy to promoted the use of.
The technical scheme of the utility model is; A kind of heavy caliber glass chromatography column support; On base, vertically be provided with support; On this support fixed head is installed, it is characterized in that, described fixed head with the mounting means of support is: said support is connected, fixes with middle bolts and nuts with the middle part of fixed head; At the top and the middle part of said fixed head, respectively be respectively arranged with scalable clip (abbreviation clip) together; Bottom at said fixed head is provided with carriage.
Support in the utility model can be around the arbitrarily angled rotation of base; Carriage, fixing hoop and locating groove are housed on the fixed head, and fixed head is connected through bolt with support, and fixed head can bolt be the arbitrarily angled rotation in center; Glass chromatography column places on the carriage, fixes through clip.
The utility model has following prioritization scheme:
Said carriage is provided with flexible material layer;
The inboard of said scalable clip also is provided with flexible material layer;
Described flexible material layer can adopt silicagel pad or foam plastic cushion;
The top of said fixed head is provided with locating groove; The bottom of said fixed head is provided with down locating groove; Cantilever tip is provided with the pilot pin corresponding with this locating groove; Described fixed card slot can keep respectively chromatographic column vertical with 45 ° on open downward-sloping, i.e. elution mode and cleaning model.
Also be enclosed with absorbent wool on the said carriage;
Described base is to be fixed on the ground through fang bolt.
The utility model patent, the problem and the advantage of solution have:
This apparatus structure is simple, and is cheap, makes heavy caliber glass chromatography easy and simple to handle, is easy to fix, operation such as simplified charging in the chromatography, discharging and dry.
This device can arbitrarily angledly rotate, and is provided with locating groove, and chromatographic column is vertical in guaranteeing to operate, and rear swivel is interior solid packing discharging of post and cleaning just, can be inverted after using up and dry.
Be lined with silicagel pad in carriage and the clip, effectively the cover glass chromatographic column has been avoided the corrosion of excessive eluent.
The absorbent wool that wraps up on the carriage can effectively absorb the moisture content that the glass chromatography column outer wall condenses in the low temperature chromatography process, avoids flowing in the receiving bottle, influences product quality.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 uses sketch map (for the side view of the Fig. 1 behind the installation glass chromatography column) for the utility model;
Fig. 3 is for fixed head and fix the rotatable direction sketch map of glass chromatography column on it;
Fig. 4 is a chromatographic column inversion state sketch map.
The specific embodiment
As shown in Figure 1, comprise base 1, fixed head 2, support 3, scalable clip 4, carriage 5, go up locating groove 6, middle bolt 7, following locating groove 8, silicagel pad 9, absorbent wool 10, pilot pin 11.
, be fixed on the ground earlier through fang bolt with base, after support inserted the base internal thread fix, fixed head passes support through bolt, and fixing, glass chromatography column is placed on the carriage fixing hoop, installation.
In the chromatography process, pilot pin is fixedly arranged in the draw-in groove of fixed head top, after separation finishes; Bolt in the middle of on the releases clamp, downward 45 ° of rotation chromatographic column end opening, pilot pin places in the draw-in groove of fixed head bottom; Water is gone out the interior fixedly phase of post, after the cleaning, is further rotated chromatographic column; Keep chromatographic column to be inverted, bolt in the middle of tightening dries.
