Description

Test tube drying equipment suitable for many sizes

Technical Field

The invention relates to the technical field of chemical auxiliary instruments, in particular to test tube drying equipment suitable for multiple sizes.

Background

Test tubes are common tools in chemical and biological laboratories and are used mainly as reaction vessels for small amounts of reagents. In order to reduce the error of the experiment and get rid of the external interference to the experiment, when using the test tube to carry out the experiment, generally need wash, disinfect and dry the test tube, just can reuse, otherwise moisture, bacterium that contain in the test tube all lead to the experiment to appear the error great easily, the experiment failure even, consequently, whether clean of test tube has decided whether the test tube can reuse immediately completely, and when carrying out multiunit experiment and comparing or observing, often need clean good test tube in a large number, also need clean, dry the test tube after the experiment finishes moreover.

However, most of the existing test tube drying methods are to spread and dry the cleaned test tube on a test table, and place the tube opening end of the test tube toward a ventilation position, so as to dry the test tube, and by adopting the drying method, water in the test tube needs to gradually flow out of the test tube, but the water in the test tube is dispersed, and the inner wall of the test tube is easy to adhere to moisture, so that the water flows out slowly or even cannot flow out, so that the drying efficiency of the test tube is low, the drying effect is poor, so that people cannot use the test tube in time after cleaning, the time and frequency for using the test tube by people are greatly limited, inconvenience is brought to the experiments of people, and the test tube rolls even when the test tube is dried, so that the test tube is damaged; in addition, people need distinguish test tube nose end and seal end earlier when putting the test tube, have also greatly reduced the efficiency that people dried in the air the test tube in the stand, and people often can forget to distinguish test tube nose end and seal end at the actual in-process of placing, lead to the test tube to place also unable complete drying for a long time, influence the use and the collection of test tube.
