Abstract
The utility model relates to a test tube sleeve, belonging to the field of laboratory apparatuses, in particular to test tube accessories. The test tube sleeve comprises a circular annular test tube sleeve body, and an exocentric pick-end slot opening convenient to pouring out liquid is arranged at the upper end of the test tube sleeve body. In use, the test tube sleeve is jointed with a test tube in a sleeving manner, and then a solution can flow out from the pick-end slot opening when the solution in the test tube is poured out and can conveniently fall into a small-mouth container, thus a problem of solution leakage when the solution is transferred to the small-mouth container (such as a cuvette) can be effectively prevented, and the pollution on a laboratory due to the solution leakage, the waste of medicines and the direct contact between the medicines and human skin can be effectively prevented; simultaneously, the test tube sleeve disclosed by the utility model has a simple structure and also is very convenient to use.
Description
Technical field
The utility model belongs to the experiment instrument field, particularly belongs to a kind of test tube accessory.
Background technology
In the laboratory experimentizes process, often from test tube in cuvette pouring soln also survey its absorbance, the frequency of its use is very high.Yet the place that common test tube in use comes with some shortcomings; The cuvette mouth is less because the test tube mouth is big during such as each pouring soln; When shifting solution to cuvette, tend to take place the phenomenon that solution overflows; The easy like this waste that causes medicine, breadboard pollution directly contacts human body skin with medicine, for our experiment brings some inconvenience.
Summary of the invention
The purpose of the utility model is in order to solve the inconvenient problem of pouring soln that common test tube in use exists, a kind of convenient and practical test tube cover to be provided.
The described test tube cover of the utility model comprises the test tube cover body of circular ring type, and test tube cover body upper end has the sharp mouth notch of the extroversion of being convenient to pouring liquid.During use, test tube cover and the mode of test tube with socket are bonded together, like this, solution just can flow out from sharp mouth notch during solution in toppling over test tube, and solution can be taken advantage of a situation and fallen into the osculum container.
The beneficial effect of the utility model is: can avoid the problem that solution overflows to osculum container (like cuvette) transfer solution the time effectively; Prevented effectively to cause laboratory pollution because of solution overflows; The waste of medicine directly contacts human body skin with medicine; Simultaneously, simple in structure, use also very convenient.
Description of drawings
The utility model has 2 width of cloth accompanying drawings.
Fig. 1 is the structural principle sketch map of the utility model.
Principle schematic when Fig. 2 is used for the utility model and test tube.
In the drawings, 1-test tube cover body; 2-point mouth notch; The 3-test tube.
The specific embodiment
Like accompanying drawing 1, shown in 2, the test tube cover that the utility model provided comprises the test tube cover body 1 of circular ring type, and test tube cover body 1 upper end has the sharp mouth notch 2 of the extroversion of being convenient to pouring liquid.During use, test tube cover and the mode of test tube 3 with socket are bonded together, like this, solution just can flow out from sharp mouth notch 2 during solution in toppling over test tube, and solution can be taken advantage of a situation and fallen into the osculum container.
