Abstract
The utility model relates to a test tube demonstrating jack horse for biological teaching, in particular to test tube demonstrating experimental rack equipment in the technical field of biological teaching facilities. The test tube demonstrating jack horse for biological teaching is characterized in that a supporting rack, two layers of flat-plate test tube racks and upright plates at the front face and the back face are connected to a base, a plurality of test tube placing circular holes and a plurality of test tube placing circular grooves are respectively arranged on the two layers of flat-plate test tube racks, the test tube placing circular holes are test tube placing circular openings, the test tube placing circular grooves are test tube placing circular bottoms, the test tube placing circular holes and the test tube placing circular grooves are mutually symmetrical so as to form a test tube placing model, background paper with different colors is placed between the upright plate at the front face and the upright plate at the back face, both sides of the upright plate at the front face are provided with scale marks, and the tops of the upright plate at the front face and the upright plate at the back face are connected and fixed on the base by the supporting rack. The test tube demonstrating jack horse for biological teaching has the effects that the structure is simple, the operation is convenient, the conditions that the steps and the effect of an experiment are observed by students and the test tube demonstrating experiment is contrastively carried out are not influenced, and the test tube demonstrating jack horse for biological teaching is widely used for teaching demonstration facility rack equipment for the experiments of various biochemical reactions in test tubes.
Description
Technical field:
The utility model relates to a kind of bioconversion medium and demonstrates stand with test tube, and particularly the test tube lecture experiment in the bioconversion medium equipment technical field sets up and is equipped with.
Background technology:
At present, chemistry or the most frequently used lecture experiment of biological teacher are the test tube experiments in the teaching equipment technical field, and when utilizing test tube to do experiment, a lot of teachers are because handgrip part is improper, be easy to block the observation of student, influence teaching efficiency experimental phenomena and experimental implementation; The teacher is not easy to instruction of papil and observes keypoint part when hand-held test tube lecture experiment, also is not easy in time add medicine or order is added medicine, the experiment of some heat release teacher's health of may burning.
Summary of the invention:
The purpose of this utility model, provide a kind of bioconversion medium and demonstrate stand with test tube, it is to adopt the transparent high temperature resistant plastic material to make, two-layer dull and stereotyped rack for test tube and two risers and graduation mark are set on the base, many test tubes are set respectively on the two-layer dull and stereotyped rack for test tube place circular hole and many test tubes placement circular grooves, place the background paper of different colours between two risers, help demonstrating reaction color phenomenon contrast, realize the clear significant purpose of observing effect of test tube experimental implementation.
The utility model bioconversion medium takes following technical scheme to realize with test tube demonstration stand, it is to be integral by base and dull and stereotyped rack for test tube and front-back riser and supporting framework, connect bracing frame and two-layer dull and stereotyped rack for test tube and front-back riser on the base, many test tubes are set respectively on the two-layer dull and stereotyped rack for test tube place circular hole and many test tubes placement circular grooves, it is that test tube is placed round mouth that many test tubes are placed circular hole, it is that test tube is placed round bottom that many test tubes are placed circular groove, many test tube placement circular holes and many test tubes are placed circular grooves and are constituted the moulding of placement test tube symmetrically, place the background paper of different colours between front riser and the back riser, riser both sides, front are provided with graduation mark, front riser and riser top, back are fastened on the base by bracing frame, and framework sheet material adopts the transparent high temperature resistant plastic material to be made into.
The utility model bioconversion medium is simple in structure with the effect of test tube demonstration stand, easy to operate, test tube demonstration effect is clear significantly, do not influence observation of students test procedure and effect, single test can adopt the demonstration of number of chemical reagent, the test tube Demonstrator Trials is carried out in contrast, is widely used in teaching demonstration equipment that various biochemical reactions test in vitro and sets up and be equipped with.
Description of drawings:
The utility model bioconversion medium will describe in further detail in conjunction with the accompanying drawings with test tube demonstration stand.
Accompanying drawing is the structural representation of the utility model bioconversion medium with test tube demonstration stand.
