Description

A laboratory cryogenic box

technical field

The utility model relates to the field of biological and chemical laboratory supplies, more particularly, to a laboratory cryogenic box.

Background technique

A large number of experiments need to be carried out at low temperature. Ice bath, ice water bath or low temperature water bath are the most commonly used methods to keep samples at low temperature during operation. At present, ice bath devices used in laboratories are mostly simple devices for experimenters, such as a foam box filled with ice. After that, the experiment was carried out directly on the ice surface. All kinds of reagent tubes and reagent bottles used in the experiment were placed on the ice surface in a disorderly manner, which could easily lead to the failure of the experiment due to the disordered order of adding reagents. In addition, the PCR experiment is the most common ice bath experiment, and it is also an error-prone experiment. The well plates used for PCR are often placed directly on the ice surface and are easy to slide, which often causes irreversible effects on the experiment. Therefore, a new laboratory cryobox is needed.

The sample support plate is provided with a tube area and a plate area, the tube area is provided with a plurality of EP tube through holes for placing EP tubes, the plate area is provided with one or more microplate support parts, the micropores are The plate support part includes a micro-plate through hole and a supporting component, the micro-plate through-hole is configured to accommodate a micro-plate, the supporting component is arranged at the bottom of the micro-plate through-hole, and is connected with the sample support plate main connection. Preferably, the through holes of the microplate are rectangular.

When the experimenter operates, the box body is filled with ice, ice-water mixture or low temperature water until the ice surface or the water surface basically contacts the lower surface of the sample support plate, and then the sample support plate is installed in the low temperature box. The cryogenic box allows the experimenter to conveniently and neatly place the EP tube in the tube area and place the microplate in the plate area, so that the EP tube and the microplate are not easily overturned and maintain an orderly operating environment during low temperature operation.

In a specific embodiment, the support assembly is fixedly connected to the main body of the sample support plate. Specifically, the support component is a support foot, which is arranged below the four sides of the through hole of the microplate. The feet have a simple structure and are easy to operate.

In another embodiment, the support assembly is a support rod, and the microplate support portion includes 2 or more of the support rods.

Preferably, the support rod is arranged to be parallel to the short side of the through hole of the microplate, and can slide along the direction of the long side. This setting allows the user to adjust the support rod in a proper position according to the size of the microplate, thereby facilitating the support of the microplate.

In a preferred embodiment, the pipe area is provided with EP pipe through holes of various sizes. During the experiment, EP tubes of different sizes are often used according to different volumes, ranging from 50 μL to 50 mL. Various sizes of EP pipe through holes can be provided to place EP pipes of different sizes.

In a preferred embodiment, the tubular section is removable. The advantage of arranging detachable pipe sections is that pipe sections with different sizes of EP pipe through-holes can be set, and a suitable pipe section can be selected to be installed on the sample support plate according to specific experiments.

In a preferred embodiment, a handle is provided on the outside of the box to facilitate moving the cryobox.

Detailed ways

The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

Example 1

As shown in FIGS. 1 and 2 , the laboratory cryogenic box of this embodiment includes a box body 1 and a sample support plate 2 . The upper part of the box body 1 is opened, and the sample support plate 2 is detachably mounted on the box body 1 . Make the board surface of the support plate 2 parallel to the bottom surface of the box body 1 on the inner wall of the box;

The sample support plate 2 is provided with a tube area 21 and a plate area 22. The tube area 21 is provided with a plurality of EP tube through holes for placing EP tubes. In this embodiment, two sizes of EP tube through holes are provided. More sizes of EP pipe through holes can also be provided.

The plate area 22 is provided with two microplate support parts, and each microplate support part is composed of a microplate through hole 221 and a support component 222, and the microplate through hole 221 is configured to accommodate micropores. The support assembly 222 is disposed at the bottom of the through hole 221 of the microplate, and is connected to the main body of the sample support plate 2 .

The through-hole 221 of the micro-plate is rectangular, and the supporting component 222 is a support foot, which is fixedly connected under the four sides of the through-hole 221 of the micro-plate.

It should be noted that, although the shape of the through hole of the microplate and the position of the support component are specifically limited in this embodiment, this does not affect the use of other shapes of the through hole of the microplate by those skilled in the art, and the adjustment of the support component. The shape and position can be set differently, and it is only necessary to set the microplate to pass through the microplate through hole and keep the microplate from detaching from the sample support plate.

A handle can be provided on the box body 1 to facilitate movement and handling.

Example 2
