Description

Technical Field

[0001] This utility model relates to the field of gun head plate technology in gun head box, specifically a novel experimental gun head plate that is detachable and can accommodate multiple specifications of gun head combinations. Background Technology

[0002] This invention relates to a pipette tip tray suitable for loading various sizes of pipette tips for complex experiments. It is an essential piece of equipment in scientific research experiments and is widely used in fields such as biochemistry and biomedicine. It is frequently used in experiments in these fields, including detection and analysis, transgenic experiments, and microbiological experiments. Currently, most pipette tip trays can only hold one fixed size of pipette tip, which cannot meet the needs of simultaneously using different sizes of pipette tips in experiments. Most biological experiments require aseptic operation, demanding that the experimental consumables used be sterile and uncontaminated. As a container for pipette tips, the pipette tip tray should be easy to use and sterilize conveniently. Therefore, it is necessary to integrate existing pipette tip trays to enable the simultaneous use of multiple sizes of pipette tips. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of deformation and breakage of pipette tip trays due to high-temperature sterilization, and to provide a novel detachable pipette tip tray for laboratory use that can accommodate combinations of multiple pipette tip sizes without the need to replace the pipette tip box. This invention has a simple structure and is highly practical.

[0004] The present invention discloses a detachable gun head plate that can accommodate multiple specifications of gun heads. The technical solution is that the gun head plate includes a thickened PP material gun head plate body, gun head insertion holes of different specifications, and a miniature buckle for replacing gun head boxes.

[0005] The thickened PP material gun head disc body is rectangular in shape and further divided into 3 smaller rectangular areas.

[0006] The different specifications of the gun head insertion holes are open and have different sizes to suit different specifications of gun heads. The outermost gun head insertion hole is 0.5 cm away from the edge of the gun head plate.

[0007] There are three miniature clips for the replaceable gun head box, which are located at the center of the outer end of the three sizes of gun head areas on the gun head plate body. They are upright, flat, rectangular prisms with a length of 1.5 cm.

[0008] Furthermore, the thickened PP material gun head disc body, gun head insertion holes of different specifications, and miniature buckles for replacing gun head boxes are integral structures.

[0009] Furthermore, the diameter of the different nozzle insertion holes corresponds to the outer diameter of the 2 μL, 200 μL, and 1.0 ml nozzles.

[0010] Furthermore, the aforementioned micro-buckles can all be secured to commercially available gun head boxes.

[0011] Furthermore, the nozzle plate body, nozzle insertion holes of different specifications, and miniature buckles for nozzle replacement boxes are all made of thickened PP material that is resistant to 121℃ high-temperature sterilization, has strong impact resistance, and is more durable (bending resistant).

[0012] The beneficial effects of this utility model are: the thickened PP material can effectively prevent the pipette tip tray from thermal expansion and contraction and deformation caused by high temperature under different sterilization conditions; the different specifications of pipette tip insertion holes can realize multiple uses of one box to facilitate the completion of the entire experiment; the miniature buckle for changing pipette tip boxes can facilitate the placement and removal of pipette tips on the pipette tip tray, and can also prevent the pipette tips in the three different areas from tipping over and falling apart. Attached Figure Description

[0013] Appendix Figure 1 This is a top view of the present invention; attached. Figure 2 This is a front view of the present invention; The attached diagram shows: a thickened PP material nozzle disc body, nozzle insertion holes of different sizes, and a miniature clip for replacing nozzle boxes. Detailed Implementation

[0014] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings and specific examples. However, the embodiments of this utility model are only used to clearly illustrate and explain this utility model, and are not intended to limit the scope and implementation of this utility model in any way.

[0015] This utility model includes a thickened PP material gun head disc body, gun head insertion holes of different specifications, and a miniature buckle for replacing gun head boxes. The thickened PP material gun head disc body, gun head insertion holes of different specifications, and miniature buckle for replacing gun head boxes are an integral structure. The gun head insertion holes are used to fix gun heads of different specifications.

[0016] Photo attached Figure 1 and attached Figure 2 The thickened PP material gun head disc has a body thickness of 0.5 cm, and the three gun head areas of different specifications have a thickness of 0.5 cm. The overall shape is a right-angled trapezoid with an overall length of 12 cm and a width of 8 cm.

[0017] The different sizes of pipette tip insertion holes are mainly divided into three areas: the upper left area is for 2 μl and 10 μl universal pipette tips, the lower left area is for 20 μl and 200 μl universal pipette tips, and the right side area is for 1 ml universal pipette tips.

[0018] The replaceable nozzle box has three miniature clips, one on the outer side of each of the three nozzle areas of different sizes, which can better secure the nozzles in each area and prevent them from tipping over and falling apart.

[0019] The aforementioned micro-buckles used to manufacture the nozzle tray body, nozzle insertion holes of different specifications, and nozzle replacement boxes are all made of thickened PP material that is resistant to 121℃ high-temperature sterilization, has strong impact resistance, and is more durable (bending resistant).

[0020] This invention not only ensures that complex experiments do not require frequent replacement and opening of different specification pipette tip boxes, thus improving experimental efficiency, but also avoids sample leakage and contamination during the experiment, thereby increasing the utilization rate of experimental table space.
