Description

Multi-functional laboratory test tube rack

technical field

The utility model relates to a chemical laboratory instrument, in particular to a multifunctional laboratory test tube rack.

Background technique

In chemical experiments, after the solution is added to the test tube, it is often necessary to keep it at a certain temperature to maintain its properties or meet the reaction conditions. The current test tube rack usually does not have a heating function, and the test tube needs to be heated by an external heating device, which is cumbersome to operate. The disadvantages of this operation method are particularly prominent when multiple groups of samples are compared and tested at the same time, and the efficiency is greatly reduced. In addition, there are also a small number of test tube racks with heating function at present, but the number of test tubes placed in them is often small, which is difficult to meet the experimental needs. In addition, most of them are heated by electric heating wires. Due to the small and unstable contact area with the test tubes, the Uneven heating, low efficiency, serious heat waste, poor laboratory application effect.

Utility model content

In order to overcome the above technical problems, the utility model provides a multifunctional laboratory test tube rack with reasonable structure design, convenient and fast operation, uniform heating of test tubes, fast heating speed, low energy consumption and large test tube placement capacity.

In order to achieve the above-mentioned technical purpose, the utility model adopts the following scheme: a multifunctional laboratory test tube rack, including a base and a box body located on the base, a number of vertically placed test tube covers are arranged in the box body, and test tube covers are installed with temperature sensor; the test tube cover is spirally wound by a hollow rubber tube, the lower end is connected with a liquid inlet pipe, the upper end is connected with a liquid outlet pipe, and a switch for controlling the on-off of the pipeline is provided on the test tube cover; the base There is a heating water tank, a power supply and a controller inside. The power supply supplies power to the heating water tank, and the controller controls the power supply and temperature sensor to work; the heating water tank is connected with a liquid supply pipe and a liquid return pipe through a circulation pump. The liquid pipe is connected with the liquid inlet pipes of several test tube sets, and the liquid return pipe is connected with the liquid outlet pipes of several test tube sets; one end of the base is provided with an inclined operation panel, and the operation panel is provided with a The display screen and control buttons connected to the controller.

The utility model has the following beneficial effects: the hot water in the heating water tank is pumped into the test tube casing through the circulation pump to circulate and flow, and can serve the purpose of heating the test tube. With the above-mentioned design, only one heating device is needed to supply heat to several test tube covers, the working status of each test tube cover can be controlled through the switch, and the working status of each test tube cover can be fed back through the temperature sensor. Its structure is simple and easy to use. Since the test tube cover is spirally wound with a hollow rubber tube, it is in close contact with the test tube wall, and can quickly and uniformly heat the test tube. The heating efficiency is high, and the number of test tubes that can be placed is large. sex.
