Abstract
The utility model relates to drawing of a metal phase diagram in physical and chemical experiments, in particular to a test tube which is convenient and safe to operate. In order to solve the technical problems, the test tube adopts the scheme that the test tube comprises a sleeve consisting of a large flat-bottomed cylindrical glass test tube and a small flat-bottomed cylindrical glass test tube; a tube orifice of the large flat-bottomed cylindrical glass test tube is connected with a tube orifice of the small flat-bottomed cylindrical glass test tube; and both sides of the tube orifice of the large flat-bottomed cylindrical glass test tube are connected with L-shaped circular tubes symmetrically. Due to the sleeve consisting of the large flat-bottomed cylindrical glass test tube and the small flat-bottomed cylindrical glass test tube, a flat bottom can prevent bottom glass from cracking when the bottom of the test tube impacts on a hard object. Both sides of the tube orifice of the large flat-bottomed cylindrical glass test tube are connected with the L-shaped circular tubes symmetrically, so that the structure is balanced, a sample can be added conveniently, molten metal liquid in the test tube can be prevented from spilling at an excess temperature, and the test tube is convenient and safe.
Description
Technical field
The utility model relates to the drafting of metal phase diagram in the Physical Chemistry Experiment, specifically a kind of easy to operate, safe test tube.
Background technology
The Physical Chemistry Experiment metal phase diagram is drawn the sleeve pipe that the test tube that adopts is two round bottom teat glasses compositions of size at present, and the large cuvette mouth of pipe links together; The Boiling tube mouth of pipe has a horizontal pipe in order to add sample; Place metal sample in the layer glass pipe, main laying temperature sensor or thermometer in the inner glass pipe.
The test tube of this kind structure following problem can occur in specific operation process: the asymmetric meeting of structure disequilibrium, and the inequality of being heated is difficult for placing, and is easy to cracking if circular test tube bottom runs into hard thing; If the excess Temperature of heating, metal are understood melting even gone out by horizontal pipe, there is potential safety hazard.For convenient, safe testing, be badly in need of a kind of special test tube.
The utility model content
The purpose of this utility model is to provide the test tube of a kind of convenience, safety.
The scheme that the utility model solve the technical problem is: a kind of test tube comprises that the big or small flat cylindrical glass test tube mouth of pipe links together by two sleeve pipes that flat cylindrical glass test tube forms of size; Large flat cylindrical glass test tube mouth of pipe bilateral symmetry connects L shaped pipe.
By two sleeve pipes that flat cylindrical glass test tube forms of size, flat can prevent that test tube bottom from colliding with hard thing the time bottom glass crack; Large flat cylindrical glass test tube mouth of pipe bilateral symmetry connects L shaped pipe, and constitutional balance can conveniently add sample on the one hand, the motlten metal liquid of test tube inside ejection in the time of can preventing excess Temperature on the other hand.
Of the present utility model have a following beneficial effect:
The utility model changes the round bottom glass bushing into flat glass bushing, and bottom glass cracks in the time of can preventing the test tube bottom with hard thing collision.Large flat cylindrical glass test tube mouth of pipe bilateral symmetry connects L shaped pipe, and constitutional balance can conveniently add sample on the one hand, the motlten metal liquid of test tube inside ejection in the time of can preventing excess Temperature on the other hand, convenient, safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of test tube, comprise large flat cylindrical glass test tube 1, little flat cylindrical glass test tube 2, described large flat cylindrical glass test tube 1 and little flat cylindrical glass test tube 2 form sleeve pipe, the flat cylindrical glass test tube mouth of pipe of size links together, and large flat cylindrical glass test tube mouth of pipe bilateral symmetry connects L shaped pipe 3.
Claims (1)
1. test tube, it is characterized in that: comprise large flat cylindrical glass test tube (1), little flat cylindrical glass test tube (2), described large flat cylindrical glass test tube (1) and little flat cylindrical glass test tube (2) form sleeve pipe, the flat cylindrical glass test tube mouth of pipe of size links together, and large flat cylindrical glass test tube mouth of pipe bilateral symmetry connects L shaped pipe (3).
