[0002] Currently, pipettes and multi-channel pipettes are available on the market. However, due to the higher cost of multi-channel pipettes, most laboratories only purchase multi-channel pipettes for use. This results in the use of pipettes instead in some scenarios where multi-channel pipettes should be used, which greatly reduces experimental efficiency.

[0003] Moreover, the existing array guns cannot be used to experiment with 1-channel to 8-channel conversion, nor can they meet the needs of experimenters. Therefore, how to solve the above-mentioned dilemma has become an urgent problem for those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a laboratory pipette dispensing device to solve the problem that existing technologies cannot use pipettes or pipettes to convert 1 channel to 8 channels.

[0005] To address the aforementioned technical problems, this utility model provides a laboratory pipette dispensing device, comprising a pipette connection channel, a primary dispensing channel, a secondary dispensing channel, a tertiary dispensing channel, and dispensing tips; the inlet end of the pipette connection channel is connected to the nozzle of a pipette, and the outlet end of the pipette connection channel is connected in parallel to two of the primary dispensing channels; the outlet ends of the two primary dispensing channels are each connected in parallel to two of the secondary dispensing channels; the outlet ends of the four secondary dispensing channels are each connected in parallel to two of the tertiary dispensing channels; the outlet ends of the eight tertiary dispensing channels are all connected to the dispensing tips; and the dispensing directions of the eight dispensing tips are consistent.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] This invention provides a laboratory pipette dispensing device, the implementation of which is as follows: Figure 1 As shown, the device includes a pipette connection channel 100, a primary diversion channel 10, a secondary diversion channel 20, a tertiary diversion channel 30, and a dispensing tip 40. The inlet end of the pipette connection channel 100 is connected to the nozzle of a pipette. The outlet end of the pipette connection channel 100 is connected in parallel to two primary diversion channels 10. The outlet ends of the two primary diversion channels 10 are each connected in parallel to two secondary diversion channels 20. The outlet ends of the four secondary diversion channels 20 are each connected in parallel to two tertiary diversion channels 30. The outlet ends of the eight tertiary diversion channels 30 are each connected to a dispensing tip 40. The dispensing tips 40 all have the same outlet direction.

[0028] In application, the nozzle of a pipette (such as a 1000ul or 200ul pipette) can be connected to the inlet end of the pipette connection channel 100. The liquid output from the pipette will then flow into the pipette connection channel 100, and then be sequentially split into the primary split channel 10, the secondary split channel 20, and the tertiary split channel 30, and finally output through eight dispensing tips 40. Therefore, this solution can be directly matched with existing pipettes, eliminating the need to purchase expensive dispensing pipettes, and realizing the splitting of 1 channel into 8 channels, effectively solving the problem that existing technologies cannot use pipettes or dispensing pipettes to convert 1 channel into 8 channels.

[0029] like Figure 1 As shown, in this embodiment, the pipette connection channel 100, the primary diversion channel 10, the secondary diversion channel 20, the tertiary diversion channel 30, and the dispensing tip 40 are all arranged in the same plane.

[0030] This setup allows for easy matching and application with multiple test tubes arranged in a straight line on the well plate.

[0031] like Figure 1 As shown, this embodiment sets up a primary diversion channel 10 including a primary inclined tube section 11 and a primary straight tube section 12 that are connected to each other; the inlet end of the primary inclined tube section 11 is connected to the outlet end of the pipette connection channel 100, and the primary inclined tube section 11 extends obliquely outward from the pipette connection channel 100; the outlet end of the primary straight tube section 12 is connected to the inlet end of the secondary diversion channel 20, and the central axial direction of the primary straight tube section 12 is consistent with the central axis direction of the pipette connection channel 100.

[0032] With this setup, the pipette connection channel 100 can be used to divert liquid to the primary diversion channel 10 in a space-saving manner.

[0033] like Figure 1 As shown, this embodiment sets up a secondary diversion channel 20, which includes a secondary inclined tube section 21 and a secondary straight tube section 22 that are connected to each other. The inlet end of the secondary inclined tube section 21 is connected to the outlet end of the primary diversion channel 10, and the secondary inclined tube section 21 extends obliquely to the outside of the primary diversion channel 10. The outlet end of the secondary straight tube section 22 is connected to the inlet end of the tertiary diversion channel 30, and the central axial direction of the secondary straight tube section 22 is consistent with the central axis direction of the pipette connection channel 100.

[0034] With this setup, the flow can be routed from the primary distribution channel 10 to the secondary distribution channel 20 in a smaller space.

[0035] like Figure 1As shown, this embodiment provides a three-stage diversion channel 30, which includes a three-stage inclined tube section 31 and a three-stage straight tube section 32 that are interconnected. The inlet end of the three-stage inclined tube section 31 is connected to the outlet end of the two-stage diversion channel 20, and the three-stage inclined tube section 31 extends obliquely to the outside of the two-stage diversion channel 20. The outlet end of the three-stage straight tube section 32 is connected to the inlet end of the dispensing nozzle 40, and the central axial direction of the three-stage straight tube section 32 is consistent with the central axis direction of the pipette connection channel 100.

[0036] With this setup, the secondary diversion channel 20 can be used to divert traffic to the tertiary diversion channel 30 in a smaller space.

[0037] like Figure 1 As shown, this embodiment of the laboratory pipette dispensing device also includes a protective cover 50, which surrounds the pipette connection channel 100, the primary dispensing channel 10, the secondary dispensing channel 20, and the tertiary dispensing channel 30.

[0038] With this setup, the protective cover 50 can protect the pipette connection channel 100, the primary diversion channel 10, the secondary diversion channel 20, and the tertiary diversion channel 30, preventing damage to the laboratory pipette dispensing device during use.

[0039] like Figure 1 As shown, in this embodiment, eight dispensing nozzles 40 are arranged at equal intervals with their central axes parallel. Specifically, in this embodiment, the distance between any two adjacent dispensing nozzles 40 is 9 mm.

[0040] With this setup, the spacing of the separatory tips 40 is consistent with the spacing of the 96-well plate, which greatly facilitates the experimental operation.

[0041] like Figure 1 As shown, in this embodiment, the liquid outlets of eight dispensing nozzles 40 are arranged in the same plane.

[0042] By adopting this setting, the consistency of liquid output from the eight dispensing nozzles 40 can be ensured.

[0043] Preferably, the laboratory pipette dispensing device in this embodiment is made of PP polypropylene.

[0044] This setup ensures the durability of the laboratory pipette dispensing device and reduces its manufacturing costs.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
