Abstract
The utility model provides a chromatography sample applicator on paper, belonging to the technical field of biological teaching apparatuses, wherein a handle is perpendicularly arranged on a clamp plate, the upper end of a casing is connected on a slide block, and the slide block is connected with the clamp plate through a dovetail groove in a sliding way, and a spring and a capillary casing are arranged in the sleeve, wherein the capillary casing is provided with a capillary tube inside, and a rubber cushion is arranged between the outer wall of the capillary tube and the inner wall of the capillary tube. One end of the spring in the sleeve is fixedly connected with the slide block, and the other end thereof is fixedly connected with one end of the capillary casing, and the clamp plate is provided with a group or groups of assemblies which are respectively formed by the slide block, the sleeve, the capillary casing and the capillary tube. The utility model utilizes the spring to provide the buffer effect, thereby avoiding the breakage of the capillary tube caused by the brute force of an operator, also realizing consistent size and even strength of sample application for a plurality of samples, being beneficial for simultaneous sampling or contrast sampling, and realizing unidirectional chromatography or bidirectional chromatography.
Description
Technical field
The utility model relates to bioconversion medium technique with the apparatus field, chromatography sample applicator on specifically a kind of paper.
Background technology
General in bioconversion medium or Bioexperiment process, often use special separation method certain potpourri to be separated the characteristic that is used for analyzing this material.For example: make the separation of chloroplast pigment of the method for chromatography on the paper, in time, use exactly blade pulverized, hand-held kapillary leaches green liquid, point sample on filter paper, with filter paper one end be inserted in chromatographic solution (sherwood oil) in, then because the different solubility of four kinds of pigments in chromatographic solution just launches 4 pigment zones on filter paper.Observe out the relative content and the kind of various pigments thus, this method is exactly to do paper chromatography with the method for point sample.In the experiment or the process of operation, point sample all be by the operator with hand-held kapillary point sample on filter paper because that the power of hand is affectedly bashful is inaccurate, often cause the kapillary fracture to cause the unsuccessful of experiment.Since be the contrast experiment through regular meeting in the experiment, thus operation required sometimes accurately, point sample size uniformity, the method for free-hand point sample is difficult to grasp.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and chromatography sample applicator on a kind of paper is provided.
The technical solution of the utility model realizes in the following manner, chromatography sample applicator on this paper, its structure comprises handle, pressing plate, sleeve, kapillary sleeve pipe and kapillary, what handle was vertical is arranged on the pressing plate, the sleeve pipe upper end is connected on the slide block, and slide block and pressing plate are slidingly connected by dovetail groove, are provided with spring and kapillary sleeve pipe in the sleeve, be provided with kapillary in the kapillary sleeve pipe, be provided with rubber blanket between kapillary outer wall and the kapillary internal surface of sleeve pipe.
One end of sleeve inner spring is fixedlyed connected with slide block, and the other end is fixedlyed connected with kapillary sleeve pipe one end.
Be connected with the assembly that one or more groups is made up of slide block, sleeve, kapillary sleeve pipe and kapillary by dovetail groove on the pressing plate.
The utility model has the advantages that:
Chromatography sample applicator on this paper, utilize spring can be in the point sample process effect that a buffering is provided in a flash that contacts of kapillary and filter paper, to guarantee can not cause fracture capillaceous because of operator's rough power.Be connected with the assembly that one or more groups is made up of slide block, sleeve, kapillary sleeve pipe and kapillary by dovetail groove on the pressing plate of chromatography sample applicator on this paper, can realize that many group sample point sample sizes are consistent, strength is even, help simultaneously point sample or contrast point sample, use on this paper the chromatography sample applicator can realize simple potpourri is done unidirectional chromatography or done two-dimensional chromatography for the potpourri of complexity thus.The design of dovetail groove can realize easy installation on the pressing plate; The design easy disassembly of sleeve and kapillary sleeve pipe is cleaned.
