Multifunctional laboratory box

Abstract

The invention relates to a multifunctional experimental box, which comprises a box body and a bracing frame. The box body is arranged on the bracing frame; an operating seal retainer is arranged on the box body internally provided with a fan; the box body is connected with a high-pressure steel bottle through an admitting port by a flowmeter; an exhaust opening is arranged on a box body wall; the operating seal retainer is provided with a sealing cap; a uviol lamp is also arranged on the box body, and black cloth is arranged on an outer housing of the box body; and a waterspout is also arranged on the bottom of the box body. The multifunctional experimental box solves the disadvantages that an old anaerobic box cannot contact with water and the cost is high, can be used as an anaerobic box, also can be used as a superclean bench and an aquatic tank, and also can be used for collecting volatile compounds in a pollution system such as a water body, settlings or the like at the same time. The equipment composition of the multifunctional experimental box is simple, the operation is simple, the cost is low, and the functions of the single anaerobic box, the superclean bench and the aquatic tank are integrated.

Description

technical field [0001] The invention relates to equipment for biological experiment research, in particular to a multifunctional experiment box. Background technique [0002] The impact of reducing compounds distributed in polluted water, especially volatile reduced sulfides on the environment has been paid more and more attention. However, for a long time, due to the limitation of experimental equipment, the research on reduced compounds in water and sediment has been slow. The current detection methods for reducing substances mainly use anaerobic chambers or small sealed glass containers (erlenmeyer flasks or flasks, etc.). As for the anaerobic box, there are two main types on the market at present. One is the original imported anaerobic box made in Germany, the price is about 140,000 RMB. Regardless of whether the equipment is used or not, it requires a large amount of nitrogen to be fed without interruption, so routine maintenance The cost is high; the domestic product...

Problems solved by technology

As for the anaerobic box, there are two main types on the market at present. One is the original imported anaerobic box made in Germany, the price is about 140,000 RMB. Regardless of whether the equipment is used or not, it requires a large amount of nitrogen to be fed without interruption, so routine maintenance The cost is high; the domestic product is the anaerobic box produced by Nanjing University, the price is about 60,000 yuan, and the equipment is required not to touch water

The above two anaerobic boxes not only have many shortcomings such as high price and high requirements for operating conditions, but also have a single function and use. Generally, they can only be used to provide an anaerobic environment, and the anaerobic environment is required to be free of water.

Since the above-mentioned anaerobic box is actually a sealed anaerobic environment, that is, before the experimental operation, the box is filled with nitrogen and then sealed, and all operations are completed in the box, so there are differences during the test, especially for volatile substances. Interference of the sample, thus distorting the measurement results
