Abstract
The utility model discloses a kit for experiment in senior middle school. A plurality of cavities that are in different structures are arranged in the inner sides of an upper cover and a lower cover of the kit in symmetry, a plurality of chemical experiment appliance are arranged in the cavities. A plurality of test tube holders is arranged vertically at the edge of the inner side of the upper cover and the lower cover. The chemical experiment appliances comprise a beaker, a measuring flask, a graduated flask, a flask, a test tube, a wash bottle, a test tube clamp, a dropping bottle, and a drip tube with a rubber head. The positive effect of the utility model is in that all experiment apparatus and pre-filled reagent for the experiment are prepared in the kit, therefore the scattered students experiments can connected together organically; the raw materials are saved, and the extra waste of and the pollution of pulling off the reagent is reduced; moreover, the working efficiency is increased, the labor and the time that the school and the teachers prepare the experiment for the students are reduced; the expense is saved, a large number of glass apparatus and reagent purchased for experiment are reduced, providing the chemical experiment appliances that are safe, convenient, simple and environment protected.
Description
Technical field
The utility model relates to a kind of kit, especially a kind of chemical experiment kit, particularly a kind of high school chemical experiment kit.
Background technology
Middle school student lecture on chemistry and be unable to do without experiment, and experiment needs instrument and reagent.For this reason, school, teacher remove to buy glass apparatus and reagent for preparing a large amount of manpowers of student experimenting spend and time, and glass apparatus is purchased many, causes waste, and the reagent preparation causes surplus to waste and damping pollution.
Summary of the invention
The purpose of this utility model is that organic collection is associated in together, for the student provides high school chemical experiment kit safe, convenient, simple and easy, environmental protection with student's chemical experiment fragmentary, that disperse.
To achieve these goals, the utility model adopts following technology: a kind of high school chemical experiment kit, comprise the box body of forming by upper and lower covers, it is characterized in that: the loam cake of described box body and lower cover inside are symmetrically arranged with the hole, cave that structure has nothing in common with each other, and the chemical experiment articles for use are placed in the hole in the cave.
Further, described loam cake is provided with the lower cover internal edge and is used for the vertical jack of placing test tube.
Further, described chemical experiment articles for use comprise beaker, measuring bottle, graduated cylinder, flask, test tube, wash bottle, test tube clamp, drop bottle and leather point dropper.
Good effect of the present utility model is: according to high school student's chemical experiment needs, be equipped with most of laboratory apparatus and can in advance in the kit quantitatively, decide the experiment reagent of concentration, with the student experimenting that sporadicly disperses, organic collection is associated in together, save raw material, reduced the surplus waste and the damping pollution of reagent preparation; Improved operating efficiency, reduced school, teacher for preparing a large amount of manpowers and the time that student experimenting spends; Save spending, reduced a large amount of glass apparatus and reagent that school buys for experiment; Loam cake and lower cover internal edge are provided with jack, can insert the test tube of different thicknesses, are used for the replacing test tubes frame, and a box is used more.The utility model provides chemical experiment articles for use safe, convenient, simple and easy, environmental protection for the high school student.
Description of drawings
Fig. 1 is preferred embodiment loam cake of the utility model and lower cover combination schematic diagram;
Fig. 2 is preferred embodiment loam cake of the utility model and lower cover internal structure schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2.High school chemical experiment kit of the present utility model, it is combined into by loam cake 1 and lower cover 2, and its material is a foamed plastics, and advantage is a light weight, and cost is low.Loam cake 1 and lower cover 2 inside are symmetrical arranged and are useful on the hole, a plurality of cave 3 of placing the chemical experiment articles for use, the chemical experiment articles for use that are equipped with in the cave hole 3 for beaker 31 commonly used, measuring bottle 32, flask 33, wash bottle 34 (interior dress distilled water), etc., graduated cylinder, big small test tube (experiment reagent is housed in the part small test tube) etc. can be placed in the storehouse 35 broad in the middle, test tube clamp, drop bottle (interior dress indicator) and leather point dropper etc. can be placed in the standby storehouse 36.Simultaneously in the part container also can in advance quantitatively, decide the experiment reagent of concentration.Loam cake 1 is provided with lower cover 2 internal edges and is used for vertical 16 jacks 4 placing test tube, can insert the test tube of different thicknesses, is used for the replacing test tubes frame, and a box is used more.Article are an entire combination in kit of the present utility model and the box, and are for the serial experiment indispensability, indispensable.
