Abstract
The utility model discloses the chromatogram bottle fixing devices on a kind of nitrogen evaporator, the device is placed below the syringe needle of nitrogen evaporator, including water-bath, the spring wire that the equally distributed bilayer of several rows intersects anyhow is installed in the water-bath, chromatogram bottle is equipped between the spring wire gap of the intersection, the transition that is combined into of the chromatogram bottle and spring wire coordinates, and the fixed position of chromatogram bottle is adjusted according to the needle position, and the syringe needle is inserted into chromatogram bottle.The utility model is because being that transition coordinates between spring wire and chromatogram bottle, the fixed position of chromatogram bottle can be adjusted according to the needle position on nitrogen evaporator, solves the fixed position because of nitrogen evaporator needle position Different Effects chromatogram bottle, auxiliary heat or cooling solution can be added in water-bath simultaneously, facilitate experimental implementation.In addition, limiting its scope of application also for because of chromatogram bottle difference in size using spring wire purpose, there is certain universality.
Description
Technical field
The utility model is related to the auxiliary device technical fields of nitrogen evaporator, and in particular to the chromatogram bottle on a kind of nitrogen evaporator is solid
Determine device.
Background technology
Chromatogram bottle is mainly used for containing the necessary container of solution to be measured before chromatography, is the common of chromatography laboratory
Utensil.Usually in some experimentations, need that the solution to be measured in chromatogram bottle is dried up or concentrated with nitrogen evaporator, and portion
Divide experiment that can directly be operated in chromatogram bottle, for example, pre-column derivatization can directly be incited somebody to action with nitrogen evaporator in chromatogram bottle
Component drying to be measured, is then added certain derivative reagent and is reacted, and can directly loading be analyzed after derivatization is complete, together
When, sample segment concentration can also directly carry out directly in chromatogram bottle.
Currently, unspecial fixing device, cannot with nitrogen evaporator directly to sample to be tested in chromatogram bottle carry out purging or
Concentration transfers to after the completion of often elder generation is by means of other container operations in chromatogram bottle.However, due to increasing intermediate ring
Section, will necessarily increase experimental procedure, lose in transfer process so as to cause component to be measured, be brought centainly to testing result
Experimental error, and unfavorable factors such as cause low conventional efficient, poor reproducibility, impurity pollution risk big.
Utility model content
To solve the above-mentioned problems, the utility model provides the chromatogram bottle fixing device on a kind of nitrogen evaporator, to reach
It realizes and chromatogram bottle is directly fixed on the technique effect on nitrogen evaporator, to improve conventional efficient, ensure testing result accuracy.
To achieve the above object, the technical solution of the utility model is：
A kind of chromatogram bottle fixing device on nitrogen evaporator, which is placed below the syringe needle of nitrogen evaporator, including water-bath,
The spring wire of at least one layer of vertical and horizontal cross-distribution is installed, the vertical and horizontal direction is all made of several rows and uniformly divides in the water-bath
Cloth, is equipped with chromatogram bottle between the spring wire gap of the intersection, and the chromatogram bottle and spring wire are combined into transition cooperation, described
Syringe needle is inserted into chromatogram bottle.
Further, the water-bath is made of stainless steel.
Compared with prior art, advantage is the utility model：
The utility model, can be according to the needle position tune on nitrogen evaporator because being that transition coordinates between spring wire and chromatogram bottle
The fixed position of whole chromatogram bottle, solves the fixed position because of nitrogen evaporator needle position Different Effects chromatogram bottle, while can be
Auxiliary heat or cooling solution are added in water-bath, facilitates experimental implementation.In addition, using spring wire purpose also for because chromatogram bottle it is big
Small difference limits its scope of application, has certain universality.

Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view of the utility model；
The meaning of reference numeral in figure：1, water-bath, 2, spring wire, 3, chromatogram bottle, 4, syringe needle.
Specific implementation mode
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1：
A kind of chromatogram bottle fixing device on nitrogen evaporator, the device are placed on 4 lower section of syringe needle of nitrogen evaporator, including water-bath
1, the spring wire 2 of two layers of vertical and horizontal cross-distribution is installed, wherein spring wire overall diameter is 2-5mm, two layers in the water-bath 1
Between spacing be 5-15mm.The horizontally-arranged spring wire 2 is 4-10 roots, and vertical setting of types is 4-10 roots, and spring wire spacing is 5-
20mm.Chromatogram bottle 3,3 preferred 2mL chromatogram bottles of chromatogram bottle are equipped between 2 gap of spring wire of the intersection.The chromatogram bottle 3 with
Spring wire 2 is combined into transition cooperation.
Wherein, the water-bath 1 is made of stainless steel.
In use, the 2 vertical and horizontal spacing of spring wire can be adjusted according to 3 inner diameter size of chromatogram bottle.By the needle on nitrogen evaporator
First 4 are inserted into chromatogram bottle 3, you can carry out the purging of solution to be measured in chromatogram bottle under nitrogen protection.
Above-described embodiment simply to illustrate that the utility model technical concepts and features, the purpose is to be to allow this field
Interior those of ordinary skill can understand the content of the utility model and implement according to this, can not limit the utility model with this
Protection domain.The equivalent changes or modifications that every essence according to the utility model content is made, should all cover in this reality
With in novel protection domain.
