Abstract
The invention discloses a novel experiment dropper and belongs to the technical field of laboratory equipment. The novel experiment dropper comprises an air bag, wherein a movable plug is arranged at the outlet of the airbag; the head part of the movable plug is fixed with a connecting part; a thread is formed in the connecting part; a through hole is formed between the movable plug and the connecting part; a flow pipe is connected with the connected part through a joint. The dropper is lengthened; agent can be added through the flow pipe at an arbitrary angle without any additional conduit; the dropper has an excellent sealing performance by virtue of a self-contact curve surface, and is dielectric, erosion resistant and high temperature resistant; the direction of the dropper can be arbitrarily rotated; the dropper is a kind of supplements to the laboratory instruments.
Description
Technical field
The invention belongs to laboratory equipment technical field, be specifically related to a kind of new test dropper.
Background technology
At present, the teacher of scientific research personnel or school conventionally adopts dropper to draw in reagent injecting tube when carrying out chemical experiment, when doing some sophisticated testings, dropper length can occur to be reached test tube or dropper and need to turn an angle and carry out reagent adding, need to take ancillary method to complete, efficiency is low, and effect is bad.
Summary of the invention
For addressing the above problem, the invention discloses a kind of new test dropper, dropper length lengthens, and can arbitrarily angled interpolation reagent.
For achieving the above object, technical scheme of the present invention is as follows:
A new test dropper, is characterized in that: comprise air bag, described air bag outlet is provided with motion stops, and motion stops head is fixed with connecting portion, and connecting portion is provided with screw thread, in the middle of motion stops and connecting portion, is provided with through hole, and runner pipe is connected with connecting portion by joint.
As a modification of the present invention, described air bag is that transparent plastic or silicon rubber are made.
As a modification of the present invention, described motion stops is tapered.
As a modification of the present invention, described runner pipe is metal cooling-pipe or adjustable plastic cooling hose.
As a modification of the present invention, the head of described runner pipe is tapered.
The invention has the beneficial effects as follows:
A kind of new test dropper of the present invention, dropper length lengthens, and runner pipe can arbitrarily angled interpolation reagent, without adding any conduit, only depend on self-contact curved surface can have fabulous sealing, direction arbitrarily can turn, non-conductive, corrosion-resistant, high temperature resistant, is that laboratory is used a kind of of instrument to supplement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numerals list:
1, air bag, 2, through hole, 3, motion stops, 4, connecting portion, 5, joint, 6, screw thread, 7, runner pipe, 8, the head of runner pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
As shown in the figure, a kind of new test dropper of the present invention, comprises air bag 1, described air bag 1 outlet is provided with motion stops 3, and motion stops 3 heads are fixed with connecting portion 4, and connecting portion 4 is provided with screw thread 6, motion stops 3 and the middle through hole 2 that is provided with of connecting portion 4, runner pipe 7 is connected with connecting portion 4 by joint 5.
Air bag 1 of the present invention is made for transparent plastic or silicon rubber, and wherein silicon rubber is also transparent material, uses transparent material to make air bag, can see clearly liquid in air bag number.
Motion stops 3 of the present invention is tapered, and clogging air bag mouth can leakage, and motion stops 3 is rubber or plastic material, has certain elasticity, is convenient to better and the tight-lipped subsides of air bag.
Runner pipe 7 of the present invention is metal cooling-pipe or adjustable plastic cooling hose, can make dropper length lengthen, and runner pipe can arbitrarily angled interpolation reagent, without adding any conduit, only depend on self-contact curved surface can have fabulous sealing, direction arbitrarily can turn, non-conductive, corrosion-resistant, high temperature resistant, easy to use.
The head of runner pipe 7 of the present invention is tapered, be convenient to add liquid, during work, test tube is vertical, and the head of runner pipe 7 is above test tube, unsettled, above test tube, drip liquid, runner pipe 7 can not touch test tube wall, except draw solution, tip can not contact other implements, in order to avoid impurity contamination.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being comprised of above technical characterictic.
