Description
Technical field
The utility model relates to a kind of chemical experimental unit, especially a kind of paper chromatography test unit.
Background technology
Paper chromatography, also known as paper chromatography, is often applied to the inspection of chlorophyllous pigment composition at present, the correlation test of amino acid whose qualification mensuration and some specific cells examinations.At present, when carrying out the coherent detection of paper chromatography, conventional testing equipment comprises Boiling tube, fine rule and rubber plug, wherein in vitro add developping agent, be inlaid in rubber plug by the upper end of the filter paper bar sheared afterwards, after closed rubber plug, the bottom of described filter paper bar contacts with developping agent and carries out reactions change.
Although above-mentioned method is simple, but because described filter paper is in a kind of state of outstanding dress and its quality kicks the beam, therefore filter paper a kind of bending shape often in Boiling tube, cause the uncontrollable problem of bottom length of described filter paper, its bottom may hang be loaded on developping agent liquid level on also may with the bottom connection of Boiling tube touch, thus the result of impact test, be not easy to scientific research; In addition because the upper end of filter paper is inlaid in gap that rubber plug makes, when after Adsorption of Filter Paper developping agent, due to the increase of filter paper quality, therefore probably cause filter paper to be occurred by situation about coming off in gap, thus cause the failure of test.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to facilitate filter paper to hang, and can make filter paper extension uniform pickup developping agent, a kind of paper chromatography test unit that liquid feeding dosage is controlled.
The utility model is achieved through the following technical solutions:
A kind of paper chromatography test unit, it is characterized in that: comprise a test tank made with transparent material, this test tank upper end is shaped with a gland bonnet, a pallet is shaped with between the bottom surface of sealing lid and described test tank, this pallet upper end is set with one can move up and down fixing geometrical clamp along pallet, this geometrical clamp is used for the upper end of fixing filter paper, and described pallet bottom is shaped with one for the stationary installation of fixing filter paper bottom.
And described stationary installation comprises pallet base and magnet piece, described pallet base adopts by the metal material of magnet adsorption, can clamp the bottom of described filter paper between this pallet base and described magnet piece.
And be shaped with a feed tube be connected with described test tank inside in the outer wall of described test tank, the end of this feed tube is integrally shaped with an addition funnel, and the outer wall of described feed tube is shaped with one for controlling the valve of feed tube opening and closing.
Advantage of the present utility model and good effect are:
In the utility model, pallet coordinates geometrical clamp, and pallet base and magnet piece, can fix the upper and lower end parts of filter paper respectively, thus filter paper is fully extended out, be more conducive to filter paper and absorb developping agent uniformly; In addition, the overall extensible test tank of pallet, can carry out for the fixing of filter paper outside test tank, and the suspension of filter paper of being more convenient for is installed; Namely the valve that described addition funnel coordinates feed tube and its outer wall to make according to the quantitative interpolation developping agent of the situation of test, can avoid the waste of developping agent, if it is too short and can not carry out the problem tested to it also avoid filter paper length.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of paper chromatography test unit, the utility model innovation is, comprise a test tank 1 made with transparent material, this test tank upper end is shaped with a gland bonnet 2, a pallet 3 is shaped with between the bottom surface of sealing lid and described test tank, this pallet upper end is set with a geometrical clamp 4, one side end of this geometrical clamp is shaped with a nut 11, geometrical clamp can be loosened mobile by the rotation of nut or be fixed on pallet upper end, described geometrical clamp is used for the upper end of fixing filter paper 5, and described pallet bottom is shaped with one for the stationary installation of fixing filter paper bottom.Described stationary installation comprises pallet base 7 and magnet piece 6, and described pallet base adopts by the metal material of magnet adsorption, can clamp the bottom of described filter paper between this pallet base and described magnet piece.
In the present embodiment, in order to reach the controlled object of developping agent liquid feeding, a feed tube 9 be connected with described test tank inside is shaped with in the outer wall of described test tank, the end of this feed tube is integrally shaped with an addition funnel 10, and the outer wall of described feed tube is shaped with one for controlling the valve 8 of feed tube opening and closing.
Use procedure of the present utility model is:
When the utility model uses, pallet can be shifted out by entirety in test tank by user, and by magnet piece and pallet base, first the filter paper bottom that length is applicable to is fixed, afterwards the upper end of filter paper is installed in and geometrical clamp is adjusted to by the degree of tightness of setting nut being applicable to that filter paper is fully extended in geometrical clamp and is highly then fixed, finally the pallet entirety clamping filter paper is put into the combination that test tank can complete test unit.Developping agent only need be added addition funnel and be closed the appropriate developping agent that can add and contact with filter paper bottom by the unlatching of valve regulated feed tube by user afterwards, thus starts to observe test.
In the utility model, pallet coordinates geometrical clamp, and pallet base and magnet piece, can fix the upper and lower end parts of filter paper respectively, thus filter paper is fully extended out, be more conducive to filter paper and absorb developping agent uniformly; In addition, the overall extensible test tank of pallet, can carry out for the fixing of filter paper outside test tank, and the suspension of filter paper of being more convenient for is installed; Namely the valve that described addition funnel coordinates feed tube and its outer wall to make according to the quantitative interpolation developping agent of the situation of test, can avoid the waste of developping agent, if it is too short and can not carry out the problem tested to it also avoid filter paper length.
