Abstract
The utility model discloses reaction rate measuring equipment which relates to the technical field of chemical instruments and is realized by the technical means as follows: the reaction rate measuring equipment comprises an iron support stand, a syringe, a conduit, and a big test tube, etc; the inner wall of the big test tube is provided with a magnetic boat which is absorbed by a magnet on the surface of an outer wall; the magnetic boat of the inner wall of the test tube can be driven to move up and down by moving the outer magnet, thereby leading solid drugs on the upper surface of the magnetic boat to be contacted with liquid drugs in the test tube to react; and the reaction is finished by moving the outer magnet of the test tube upwards to separate the solid drugs or catalysts from the liquid. The magnetic boat consists of the magnet and a drug storage part; the magnet is coated in the magnetic boat and a packet is not acted with the drugs; the drug storage part is of a netty shape, which is convenient for the sufficient contact between the solid and the liquid. Compared with the prior art, the reaction rate measuring equipment has the advantages of easy operation of experiment and obvious phenomenon, can control the implementation and stop of the reaction, is convenient to be used, is easy to be improved, and relates to the reaction rate measuring equipment which is very worthy of popularization.
Description
Technical field
The utility model relates to the instruments used for education that chemical reaction rate is measured, and is a kind of reaction rate determinator specifically.
Background technology
Take as an elective course in 4 " chemical principles " at senior middle school chemical teaching material, need influence the factor of reaction rate to student explain, wherein just need the influence to reaction rate such as demonstration concentration, temperature, traditional experiment is liquid to be joined carry out chemical reaction above the solid, complicated operation, and can't stop experiment, cause the waste of medicine.
The utility model content
The purpose of this utility model is the deficiency that exists at existing experiment, and a kind of reaction rate determinator is provided.
The purpose of this utility model realizes by following technological means: the reaction rate determinator, form by iron stand, syringe, conduit and Boiling tube, one magnetic boat is arranged by the attraction above the outer wall on the Boiling tube inwall, the magnetic boat that can drive inboard wall of test tube by the magnet that moves the outside moves up and down, thereby make solid medicine or catalyzer above the magnetic boat contact with invisible spectro liquid drug, reaction is carried out, move on the magnet with the test tube outside, solid medicine or catalyzer and liquid are broken away from, reaction finishes, and is convenient to control.The magnetic boat is made up of magnet and medicine storeroom two parts, and magnet is wrapped in the magnetic boat, wrappage with medicine reaction, the medicine storeroom is netted, is convenient to fully contacting of solid and liquid.
Compared with prior art the utlity model has following tangible advantage: experiment is operation easily, and phenomenon is obvious, can control reaction and carry out and stop, and is easy to use, be easy to improve, and be a kind of reaction rate determinator that promotional value is arranged very much.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
Fig. 2 is a magnetic boat enlarged drawing.
Wherein 1. rubber plugs, 2. Boiling tube, 3. solid medicine or catalyzer, 4. magnet, 5. magnetic boat, 6. liquid drug.
Embodiment
Below in conjunction with description of drawings the utility model is described in further detail:
The use of this reaction rate determinator is: add liquid drug 6 earlier in Boiling tube 2, medicine storeroom to magnetic boat 5 adds solid medicine or catalyzer 3, break away from liquid drug 6 on Boiling tube 2 inwalls with magnet 4 control magnetic boats 5, rubber plug 1 beyond the Great Wall, assemble instrument, move down magnet 4 and contact with liquid drug 6 up to solid medicine or catalyzer 3, reaction is carried out; Writing time, collect a certain amount of (as 10mL) gas after, writing time, the magnet 4 that moves up simultaneously breaks away from up to solid medicine or catalyzer 3 and liquid drug 6, experiment finishes.Open rubber plug 1, will move to 2 mouthfuls of Boiling tubes on the magnet 4, can take out solid medicine or catalyzer 3, saved medicine.
In a word, the utility model provides a kind of reaction rate determinator.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
