[0002] The gas-controlled operation rack is a tool designed to facilitate column operation. It can be used not only for immunoaffinity column operation, but also for multifunctional purification column, molecular imprinting column and other column operations. The use of the gas-controlled operation rack can process multiple samples at the same time, improve the operation efficiency, and make the operation simple and fast.

[0003] Existing pneumatic operation stands are composed of a base plate, an upper plate, and support rods. The base plate and the upper plate each have two mounting holes. There are two support rods, and the lower ends of the support rods are disposed in the mounting holes on the base plate, while the upper ends of the support rods are disposed in the mounting holes on the upper plate. In actual use, waste liquid is generated during operation, and the existing pneumatic operation stands do not have a waste liquid collection device, resulting in inconvenience in use. In addition, the existing pneumatic operation stands are in a fully open state, and when using volatile liquids, they can only be operated in a fume hood; however, in actual experimental processes, operations often need to be performed in an environment outside the laboratory, and at this time, volatile gases are prone to overflow, which is detrimental to the health of the experimenters.

[0006] Preferably, there are four adsorption magnetic blocks and positioning magnetic sheets, and the four adsorption magnetic blocks are fixed to the four corners of the waste liquid collection box by gluing. The four positioning magnetic sheets are fixed to the bottom plate by gluing. The area enclosed by the lines connecting two adjacent ones of the four positioning magnetic sheets is a rectangle, and the shape of the rectangle is the same as the shape of the lower surface of the waste liquid collection box.

[0007] Preferably, there are four fixed magnetic strips, which are fixed on the two long sides and two short sides of the upper plate respectively by gluing; the number and length of the adsorption magnetic blocks correspond to the fixed magnetic strips.

[0008] Preferably, the barrier soft material is a transparent plastic cloth, and the barrier soft material is arranged on the movable magnetic strip by gluing.

[0010] A waste liquid discharge pipe is also provided on one side of the bottom of the waste liquid collection box.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting up a waste liquid collection box, the waste liquid produced during use can be well collected to prevent the waste liquid from polluting the experimental environment. A waste liquid discharge pipe is also provided on one side of the bottom of the waste liquid collection box.

[0013] 2. The adsorption magnetic block of the utility model is arranged on the lower surface of the waste liquid collection box, and the positioning magnetic sheet is arranged on the bottom plate. The positioning magnetic sheet and the adsorption magnetic block are magnets of different polarities. The waste liquid collection box is set on the positioning magnetic sheet through the suction force between the positioning magnetic sheet and the adsorption magnetic block. It can be seen that the waste liquid collection box of the utility model is positioned and adsorbed on the bottom plate by magnetic force, which is convenient for disassembly and carrying, so that it can better adapt to different experimental environments.

[0014] 3. The barrier material of this utility model is suspended in mid-air by the attraction between the fixed and movable magnetic strips, enclosing the space between the bottom and upper plates. This allows volatile gases generated during the test to be trapped between the barrier material, the upper plate, and the bottom plate, reducing the risk of volatile gases to experimenters. This suspension of the barrier material by the attraction between the fixed and movable magnetic strips also facilitates removal and portability.

[0015] 4.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the protection scope of the present invention is not limited by the embodiments. Example 1

[0020] An improved pneumatic control operating frame, consisting of a base plate, an upper plate and a support rod, wherein the base plate and the upper plate each have two mounting holes, the support rods are two, the lower ends of the support rods are arranged in the mounting holes on the base plate, and the upper ends of the support rods are arranged in the mounting holes on the upper plate, and further comprising a waste liquid collection portion and a volatile gas barrier portion; the waste liquid collection portion is composed of a waste liquid collection box, a positioning magnetic sheet and an adsorption magnetic block; the waste liquid collection box is a rectangular parallelepiped with an opening on the upper surface, the adsorption magnetic block is arranged on the lower surface of the waste liquid collection box, and the positioning magnetic sheet is arranged on the base plate, The positioning magnetic sheet and the adsorption magnetic block are magnets of different polarities, and the waste liquid collection box is set on the positioning magnetic sheet by the suction force between the positioning magnetic sheet and the adsorption magnetic block; the volatile gas barrier part is composed of a fixed magnetic strip, a movable magnetic strip and a barrier soft material, the fixed magnetic strip is set on the lower surface of the upper plate and along the circumference of the upper plate, the barrier soft material is set on the movable magnetic strip, the fixed magnetic strip and the movable magnetic strip are magnets of different polarities, and the barrier soft material is suspended by the suction force between the fixed magnetic strip and the movable magnetic strip and surrounds the space between the bottom plate and the upper plate.

[0021] There are four adsorption magnetic blocks and positioning magnetic sheets. The four adsorption magnetic blocks are fixed to the four corners of the waste liquid collection box by gluing, and the four positioning magnetic sheets are fixed to the bottom plate by gluing. The area enclosed by the lines connecting two adjacent positioning magnetic sheets is a rectangle, and the shape of the rectangle is the same as the shape of the lower surface of the waste liquid collection box.

[0022] There are four fixed magnetic strips, which are fixed on the two long sides and two short sides of the upper plate respectively by gluing; the number and length of the adsorption magnetic blocks correspond to the fixed magnetic strips.

[0023] The barrier soft material is a transparent plastic cloth, and the barrier soft material is arranged on the movable magnetic strip by gluing.

[0024] The barrier soft material is also provided with a seam, which is arranged in the middle of the operating surface of the air control operating frame; an iron wire is arranged in the barrier soft material on one side of the seam, and a magnetic rope is arranged in the barrier soft material on the other side of the seam.

[0025] A waste liquid discharge pipe is also provided on one side of the bottom of the waste liquid collection box.

[0026] During the liquid extraction experiment, the liquid extraction column needs to be clamped to the gas-controlled operating stand described in the embodiment, and then the lower end of the extraction column is opened, and the liquid inside will drip down. The pre-extraction treatment requires adding a buffer solution to the extraction column, and then adding the sample solution. These liquids flow out from the lower end after passing through the extraction column. These flowing liquids are unnecessary and are called waste liquids. The waste liquid collection box in this embodiment can collect the waste liquid, and after the collection is completed, the waste liquid is collected and processed uniformly through the waste liquid discharge pipe on the bottom side.

[0027] At the same time, during the addition of the extract and diluent to the extraction column, the volatile extract is released directly into the air, creating a very pungent and toxic odor and posing a significant health hazard to the experimenter. By providing a barrier material, this embodiment can prevent the release of large amounts of volatile gases in a short period of time, thereby reducing the harm to the human body. Furthermore, an exhaust port can be provided on the barrier material of this embodiment, allowing simultaneous extraction of volatile gases while they are being generated, allowing the trapped volatile gases to be extracted and centrally processed.

[0028] When the experimenter needs to operate, the seam can be opened and the experimenter's hand can enter the space surrounded by the barrier soft material to operate. After the operation is completed, the iron wire on one side of the seam and the magnetic rope on the other side of the seam are attracted together under the action of magnetic force, so that the seam is closed.

[0029] When the device needs to be moved, the magnetically adsorbed components are extremely easy to disassemble, reducing the difficulty and cost of carrying the device.
