Abstract

The utility model discloses a kind of filtrate scriber, comprise the first slide, the second slide, sponge, the 3rd slide and the 4th slide; The first described slide and the second slide have angle by the bonding shape of described sponge; The same side of described the 3rd slide and the first slide and the second slide is bonding; Another of described the 4th slide and the first slide and the second slide is bonding with side; The first slide, the second slide, the 3rd slide and the 4th slide form a V groove; This filtrate scriber, select sponge to have certain water suction and the performance of water storage, by the method with slide folder sponge, solved and merely with slide, done tank and cause crack tension to be difficult for the shortcoming of flow liquid or wide not liquid storage, overall structure is simple, raw material are easy to get and cheap, just can easy manipulation without the need for any technology in the time of can making Faculty and Students draw filtrate line, practical, be easy to promote the use of.

Description

A kind of filtrate scriber

Technical field

the utility model relates to pigment and extracts and Separation Test Technology field, especially a kind of filtrate scriber.

Background technology

at present, in Senior Two textbook < < tests six chloroplasets, the extraction of pigment is with in separated > >, generally need to use writing brush, thin cotton thread or draw filtrate fine rule with capillary syring on dry qualitative filter paper, the picture that requires while drawing filtrate fine rule to try one's best is thin, drawing direct sum draws clear neat, with this, reach and prevent from partly overlapping between pigment zone, pigment molecular is uniformly distributed point-blank, accomplish to spread starting point consistent, increase the pigment molecular quantity on filtrate fine rule, make more significantly object of experiment effect.But use writing brush drawn liquidus inhomogeneous; With the bad operation of capillary syring and easily disconnected, increase experimentation cost; And because of process, point bullet with cotton cord bullet, can, because touching rope with finger, affect the color and luster of filtrate; We carry out picture filtrate line with toothpick after improving, and because toothpick does not absorb water, being used for picture filtrate line needs repeated multiple times operation cause setting-out unclear, inconvenience; Therefore, manufacture be a kind ofly both easy to use, practicality simple to operate and the cheap scriber of cost of manufacture be that people wait the problem solving.

Summary of the invention

in order to solve the defect in prior art, the utility model aims to provide a kind of practicality easy to use, simple to operate and the cheap filtrate scriber of cost of manufacture.

for realizing this technical purpose, scheme of the present utility model is: a kind of filtrate scriber, is characterized in that: comprise the first slide, the second slide, sponge, the 3rd slide and the 4th slide; The first described slide and the second slide have angle by the bonding shape of described sponge; The same side of described the 3rd slide and the first slide and the second slide is bonding; Another of described the 4th slide and the first slide and the second slide is bonding with side; The first slide, the second slide, the 3rd slide and the 4th slide form a V groove.

further, between the first described slide and the second slide, angle is 60 degree.

further, the bonding employing glass cement between the first described slide, the second slide, sponge, the 3rd slide and the 4th slide is bonding.

compared with prior art, the beneficial effects of the utility model are: this filtrate scriber, select sponge to have certain water suction and water storage performance, by the method with slide folder sponge, solved and with slide, done tank merely and cause crack tension to be difficult for the shortcoming of flow liquid or wide not liquid storage; Meanwhile, by slide being made into triangle reservoir, inner clip sponge does to cut off, and the principle by sponge leaching is imprinted on liquid on filter paper bar; Overall structure is simple, just can easy manipulation without the need for any technology in the time of can making Faculty and Students draw filtrate line, and practical, be easy to promote the use of.

Accompanying drawing explanation

fig. 1 is overall structure schematic diagram of the present utility model;

wherein component serial number and title in figure:

the first slide 1, the second slide 2, sponge 3, the 3rd slide 4, the 4th slide 5.

The specific embodiment

below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

refer to Fig. 1, in the utility model embodiment, a kind of filtrate scriber, comprises the first slide 1, the second slide 2, sponge 3, the 3rd slide 4 and the 4th slide 5; The first described slide 1 and the second slide 2 have angle by the bonding shape of described sponge 3; The same side of described the 3rd slide 4 and the first slide 1 and the second slide 2 is bonding; Another of described the 4th slide 5 and the first slide 1 and the second slide 2 is bonding with side; The first slide 1, the second slide 2, the 3rd slide 4 and the 4th slide 5 form a V groove.

further, between the first described slide 1 and the second slide 2, angle is 60 degree.

further, the bonding employing glass cement between described the first slide 1, the second slide 2, sponge 3, the 3rd slide 4 and the 4th slide 5 is bonding.

the utility model is when making: (1) first gets a slide, isometric sponge (about 3mm thick) placement is coated with the slide limit of glass cement on after being stained with glass cement on a limit;

(2) after the glass cement that is stained with sponge is dry fixing, uses the same method another piece slide is stained with and makes two slide shapes in an angle;

(3) at each sticky slide of glass cement for both sides of two slides, make it to form a triangle reservoir, these two slides also play the fixing effect of filtrate scriber of placing.

the utility model is in use: directly pour a small amount of filtrate into filtrate scriber, make filtrate saturated sponge, the method by impression prints to filtrate lines on filter paper bar, can obtain filtrate line clean, neat, straight and that thickness is well-balanced.

to those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.

the above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
