With the gradual expansion of in vitro cell culture, the late culture is usually operated in a 5L large-capacity shake flask.

[0003] However, due to the large volume of 5L shake flask, the bottle body is high, and the length of the large-capacity pipette (usually 50ml serum pipette, about 40cm long) is very inconvenient for cell passage or transfection process operation in the super-clean bench. In addition, the transfection process, especially the infection link, requires mixing and infection at the same time to avoid local high concentration and affect the inoculation effect. Moreover, the bottle mouth of the shake flask needs to be burned for several weeks for sterilization before and after opening, and the 5L shake flask has large capacity and volume, and the weight of the cell suspension is also large.

[0039] A balance bar 10 is horizontally arranged at the center line of the lower side of the bottom of the containing groove 8, the two vertical bars of the balance bar 10 are respectively hinged to the two sides of the frame body 1 to perform a pendulum motion, and a plurality of clamping grooves 11 for hinging with the frame body 1 are arranged on the vertical bars in the vertical direction;

[0040] An irradiation device is arranged at the side of the frame body 1 and is used for burning the bottle mouth of the shake flask for sterilization.

[0041] It should be noted that the containing groove 8 can be arranged as a cylindrical groove structure to facilitate the containing of the shake flask, and the containing groove 8 can be made of latex and a hard structure is arranged at the bottom of the containing groove 8, so that the circumference of the containing groove 8 is a soft structure and the bottom of the containing groove 8 is a hard structure. In this way, the containing groove 8 can move up and down with the balance bar 10 and change the depth, thereby being suitable for different models and sizes of shake flasks, and only the diameter of the containing groove 8 needs to be greater than the maximum diameter of the bottom of the shake flask.

[0042] It should be further noted that the bottom support 9 connected by a thrust bearing can be freely moved circumferentially at the inner side of the bottom of the containing groove 8, and a viscous sticky plate can be arranged on the upper surface of the bottom support 9 to fix and paste the shake flask by the viscous sticky plate.

[0045] Then, the shake flask is used for infection, transfection, feeding or subculture operation, and the height of the containing groove 8 can be adjusted again by the balance bar 10 before operation, so that the shake flask is lowered to a position where the bottle mouth of the shake flask is slightly higher than the bottom of the super-clean room 2. At the same time, the balance bar 10 can be driven to swing in a pendulum motion during the infection process, so as to realize the mixing operation of the sample liquid in the shake flask. The pendulum motion of the balance bar 10 can make the bottom of the shake flask move and mix, but the bottle mouth of the shake flask is relatively stable, so as to avoid affecting the operation of the liquid handling pipette.

[0046] The device not only facilitates single person independent operation, avoids improper cooperation of two persons, and avoids the risk that the liquid handling pipette touches the reagent bottle mouth or liquid splashes, but also effectively improves work efficiency and saves human resources. After the experiment is completed, only the super-clean room 2 and the containing groove 8 need to be cleaned and disinfected, and the glass door 3 is closed.

[0047] In summary, the super-clean workbench suitable for batched shake flask infection is suitable for batched shake flask infection and is convenient for experimental personnel to complete the operation independently.

[0048] In one embodiment, the bottom of the frame body 1 is provided with a plurality of universal silent wheels 12 and a plurality of fixed spiral foot pads 13, and at least one of the plurality of universal silent wheels 12 is provided with a brake device 23. The fixed spiral foot pad 13 facilitates the transfer and fixation of the frame body 1, and the experimental personnel can select a suitable sterile workshop according to the experimental needs, and the brake device 23 facilitates the movement and fixation of the frame body 1.

[0049] In one embodiment, the super-clean room 2 comprises two oppositely distributed side wall plates 4, a back plate 6 arranged at the back side of the two side wall plates 4, a top plate 5 arranged at the top of the two side wall plates 4, a horizontal workbench 7 arranged at the bottom of the two side wall plates 4, and a glass door 3 slidingly arranged at the front side of the two side wall plates 4; the horizontal workbench 7 is provided with a through hole in communication with the top of the containing groove 8, and the side wall plates 4, the back plate 6, the top plate 5 and the horizontal workbench 7 are of an integrated structure.

[0050] In one embodiment, the super-clean room 2 is provided with a ventilation super-clean system 14 at the top to ensure the super-clean and sterile state of the environment during the experimental operation process.

[0051] In one embodiment, the top of the containing groove 8 is provided with two oppositely distributed semicircular ring-shaped push blocks, Figure 1 which are not marked in the figure, and the two push blocks are slidingly arranged on the horizontal workbench 7 and are used to slide along the radial direction of the containing groove 8 after being subjected to force. Among them, the two push blocks are easy to push, and the two push blocks cooperate to form a circular through hole, which is used to limit the position of the bottle mouth of the shake flask, and a gap is arranged between the circular through hole and the bottle mouth, so that the push block can be pushed to move after the bottle mouth collides with the push block, so as to avoid the push block from hindering the small range swing of the shake flask.

[0052] It should be noted that, since different types of shake flasks have different sizes, in order to make the containing groove 8 suitable for various types of shake flasks, the depth of the containing groove 8 and the size of the circular through hole can be adjusted. Among them, the depth of the containing groove 8 can be adjusted by moving the position of the balance rod 10 up and down, so that the depth of the soft containing groove 8 can be increased or decreased, for example, when the balance rod 10 moves up, the depth of the containing groove 8 decreases, and when the balance rod 10 moves down, the depth of the containing groove 8 increases. The size of the circular through hole of the containing groove 8 can be adjusted, that is, the inner diameter of the containing groove 8 is unchanged (but it needs to be larger than the maximum diameter of the bottom of the shake flask), and the size of the circular through hole can be reduced or increased (that is, the size of the circular through hole can be increased or decreased by moving the push block), so that the device has good applicability, is convenient for liquid drop operation, and can reduce the risk of other components falling into the containing groove 8 during use. In addition, the operator can wear gloves and hold the bottle neck position (i.e. near the bottle mouth) of the shake flask during use.

[0053] It should be noted that, the diameter of the containing groove 8 is generally in the range of 5-50 cm, the height of the containing groove 8 can be adjusted in the range of 0-60 cm, and the shape of the containing groove 8 is not limited to Figure 1 the cylindrical groove. When a 5L cell shake flask needs to be operated, the containing groove 8 can be set as a cylindrical groove, and the inner diameter of the containing groove 8 can be set as 30 cm, and the depth of the containing groove 8 can be set as 40 cm. In actual application process, the specific shape, size, etc. of the containing groove 8 can be selected according to the type of shake flask.

[0054] In one embodiment, as shown inFigure 1 As shown, the irradiation device includes an infrared sterilization lamp 18 arranged on one side of the super-clean room 2, and an ultraviolet lamp 15, an illuminating lamp 16, a socket 17, an external three-phase power supply line 19, a power switch 20 and a control and adjustment screen 21 arranged on the other side of the super-clean room 2. The control lines of the external three-phase power supply line 19, the power switch 20 and the control and adjustment screen 21 are located in the cavity to avoid safety hazards caused by exposed control lines. The arrangement of the illuminating lamp 16, the ultraviolet lamp 15 and the infrared sterilization lamp 18 (the circuit connection relationship can refer to the lamp connection mode of the prior art) facilitates the sterilization and illumination before and after the use, and makes the operation more convenient.

[0055] It should be noted that before using the super-clean bench suitable for batch shake flask infection, the ultraviolet lamp 15 can be controlled to be turned on to make the inside of the sterilization operation table (i.e. the inside of the super-clean room 2) reach a relatively clean state by the ultraviolet lamp 15. For example, the ultraviolet lamp 15 can be controlled to be irradiated for more than 30 minutes before using the device. When using the super-clean bench suitable for batch shake flask infection, the ultraviolet lamp 15 can be controlled to be turned off, and the super-clean room 2 is in a ventilation state.

[0056] In one embodiment, the lamp rod of the infrared sterilization lamp 18 is a rod member wrapped with a silica gel member outside. The silica gel member has high heat resistance, chemical stability and non-combustible characteristics. Therefore, during use, the experimenter can bend or move the rod member to change the position of the infrared sterilization lamp 18 to ensure that the position of the shake flask that needs to be sterilized and disinfected is accurately irradiated by the infrared sterilization lamp 18.

[0057] In one embodiment, the balance rod 10 is provided with a clamping bottom support 24 for fixing the bottom of the containing groove 8 to improve the connection effect of the containing groove 8 and the balance rod 10. The two vertical rods are respectively connected to the ends of the horizontal rod through hinges, so that the containing groove 8 can be slightly rotated.

[0058] In one embodiment, the bottom of the clamping bottom support 24 is provided with a control rod 26, and the bottom of the control rod 26 is provided with a displacement control member 25 for accommodating the foot of the operator. That is, the foot of the experimenter can be inserted into the displacement control member 25, and the displacement control member 25, the control rod 26 and the clamping bottom support 24 can be moved by one foot, so as to kick the balance rod 10, and further drive the containing groove 8 and the shake flask to swing. The volume of the liquid in the shake flask is about 1 / 3 of the capacity, so the liquid will not overflow when the shake flask swings.

[0059] In one embodiment, the containing groove 8 and the clamping bottom support 24 are detachably connected. For example, an adhesive sticker can be arranged on the outer side surface of the lower part of the bottom of the containing groove 8 to be fixedly connected with the clamping bottom support 24 through the adhesive sticker, so as to ensure the structural stability of the whole device and make the mixing operation of the shake flask more safe and efficient.

[0060] In order to further illustrate the use method of the super clean bench suitable for batch shake flask virus infection provided by the utility model, examples are given as follows.

[0061] In actual use, first, the glass door 3 is closed, the containing groove 8 is placed at the lowest position, the cavity is irradiated by the ultraviolet lamp 15 for more than 40 minutes in advance, the glass door 3 is opened, and ventilation is performed for more than 20 minutes. After the surface of the shake flask to be operated and experimental equipment is disinfected by 75% alcohol, the shake flask is placed in the cavity at a proper position, the height of the containing groove 8 is adjusted to a proper position, the shake flask is fixed on the adhesive sticky plate at the bottom center position of the containing groove 8, the infrared sterilization lamp 18 is close to the interface between the bottle mouth and the bottle cap of the shake flask after reaching the highest temperature, and the shake flask is rotated for several turns to burn the outer edge of the shake flask for sterilization and disinfection. Then, the bottle cap of the shake flask is opened, and the shake flask is rotated for several turns in circumferential motion, which is beneficial to the high-temperature burning of the bottle mouth of the shake flask by the infrared sterilization lamp 18 to disinfect and sterilize the bottle mouth. Subsequently, virus infection, material supplement or subculture operation is performed, and the height of the containing groove 8 can be adjusted again before operation to make the bottle mouth of the shake flask drop to the horizontal workbench surface 7 again. In addition, during the virus infection process, the experimental personnel can insert one foot into the displacement control member 25 to drive the displacement control member 25 to swing appropriately, and the swing motion of the swing pendulum can realize the mixing operation of the sample liquid in the shake flask and ensure that the moving range of the bottle mouth is minimized, so that the sample bottle at the bottom of the containing groove 8 is shaken easily to realize the mixing operation of the sample liquid.

[0062] The device not only facilitates single person independent operation, avoids improper cooperation of two persons during cooperation, and avoids the risk of touching the reagent bottle mouth or liquid spilling of the pipette, but also effectively improves work efficiency and saves human resources. After the experiment is completed, the experimental personnel can clean and disinfect the horizontal workbench surface 7 and the containing groove 8 of the super clean room 2, then the glass door 3 is closed, the cavity is irradiated by the ultraviolet lamp 15 for more than 40 minutes, and finally the power is turned off.

[0063] The device is convenient and practical, safe and efficient, and can be sterilized and disinfected by ultraviolet irradiation before and after the experiment, and the filtration and ventilation during the experiment ensure that the whole experiment is operated in a clean environment, ensuring the sterility of the sample and avoiding pollution. The setting of the thrust bearing realizes the free circular motion of the shake flask on the bottom support 9, the design of the viscous sticky board ensures the stability, and the rotation of the shake flask bottle mouth is easily realized. Burn for several weeks to achieve sterilization and disinfection treatment, avoiding the risk of wear or spilling of the shake flask bottle bottom. The design of the convenient lifting containing groove 8 breaks the space limitation of the clean bench, and the large capacity shake flask can be fixed in the containing groove 8 and adjusted to the appropriate height, which can effectively avoid the high bottle mouth and affect the convenience of operation. In addition, since the bottom of the containing groove 8 can perform a simple pendulum motion to shake and mix the sample liquid, the maximum fluidity of the liquid in the bottle is ensured, and the displacement of the shake flask bottle mouth is minimized, which is convenient for continuous drop of virus liquid. Moreover, the original operation assisted by two people is changed to be completed independently by one person, which greatly improves the work efficiency of the experimental personnel, saves human resources, and has higher controllability, reduces the pollution risk in the process of multi-person operation, reduces the batch difference, and ensures the safe and smooth progress of the experiment.
