Description

Technical Field

[0001] The utility model relates to the technical field of biological experimental equipment, in particular to an adjustable microcentrifuge tube transfer plate. Background Art

[0002] Microcentrifuge tubes, also known as EP tubes, are small containers commonly used in biological laboratories for dispensing and handling small volumes of liquid. Available sizes include 0.2 ml, 0.5 ml, 1.5 ml, and 2.0 ml. Transferring microcentrifuge tubes is a common requirement during experimental procedures, especially for smaller tube sizes (e.g., 0.5 ml). Due to their small size, microcentrifuge tubes can be inconvenient to handle. When transferring large samples in batches, transferring them one by one is time-consuming and laborious, and can easily lead to misplacement and experimental errors. Currently, there are no dedicated microcentrifuge tube transfer plates available on the market; only microcentrifuge tube racks or microcentrifuge tube boxes are available. Therefore, an adjustable microcentrifuge tube transfer plate, designed to adjust the spacing between microcentrifuge tubes according to actual needs, is being designed for batch transfer of microcentrifuge tubes. This plate would improve operational convenience, save time and effort, and enhance operator efficiency, while also reducing experimental errors caused by misplaced transfers. Summary of the Invention

[0009] Furthermore, a silicone rubber clamping groove is provided on the inner side of the centrifuge tube slot slider for fixing the microcentrifuge tube.

[0010] Furthermore, a raised anti-slip strip is provided on the surface of the handle slider to increase the friction between the hand and the handle during operation.

[0011] Furthermore, a silicone track groove is provided on the adjusting rod, which is slidably connected to the handle track on the handle slider through the silicone track groove, so as to be used for adjusting the position of the rod on the handle slider.

[0024] like Figure 1-6 As shown, the utility model is an adjustable microcentrifuge tube transfer plate, comprising an upper track 1, a lower track 6 and two handle sliders 9, a plurality of centrifuge tube slot sliders 4 slidably connected to the upper track 1 are arranged between the upper track 1 and the lower track 6, and two adjacent centrifuge tube slot sliders 4 are connected by a connecting spring 2; the two handle sliders 9 are respectively placed at the two ends between the upper track 1 and the lower track 6, and the upper and lower ends of the two handle sliders 9 are respectively slidably connected to the upper track 1 and the lower track 6.

[0025] The two handle sliders 9 are respectively connected to the adjacent centrifuge tube slot sliders 4 via handle springs 7 .

[0026] The inner sides of the two handle sliders 9 are respectively provided with handle rails 12 arranged vertically, and the handle 12 rails of the two handle sliders 9 are respectively slidably connected with adjustment rods 10, and the two adjustment rods 10 are connected to the corresponding handle sliders 9 through adjustment springs 8; a movable groove 11 is provided on the lower track 6 along its length direction, and the lower ends of the two adjustment rods 10 are slidably sleeved in the movable groove 11.

[0027] An elastic silicone strip 5 is fixed between the two adjusting rods 10 , and the microcentrifuge tube is clamped and fixed by the cooperation between the elastic silicone strip 5 and the centrifuge tube slot slider 4 .

[0028] A slotted silica gel 3 is provided inside the centrifuge tube slot slider 4 for fixing the microcentrifuge tube.

[0029] A raised anti-slip strip is provided on the surface of the handle slider 9 to increase the friction between the hand and the handle slider 9 during operation.

[0030] The adjustment rod 10 is provided with a silicone track groove 13, which is slidably connected to the handle track 12 on the handle slider 9, and is used to adjust the position of the rod 10 on the handle slider 9. The silicone track groove 13 on the adjustment rod 10 has two functions: first, it uses the friction with the handle track 12 to prevent excessive stretching of the adjustment spring 8; second, it uses the buffering effect of the silicone itself to reduce wear of the track groove of the adjustment rod 10 and the handle track 12 under the long-term tension of the elastic silicone strip 5.

[0031] The adjustable microcentrifuge tube transfer plate is constructed from polypropylene (PP), silicone, and stainless steel springs. The transfer plate's main frame (upper rail 1 and lower rail 6) is made of PP, which offers high impact resistance, mechanical toughness, and resistance to various organic solvents, acids, and alkalis, making it suitable for use in routine laboratory conditions. The elastic silicone strip 5 is made of fluorosilicone rubber, offering excellent elongation and thermal stability. The connecting spring 2, handle spring 7, and adjustment spring 8 are all 304 stainless steel extension springs, offering high temperature resistance and toughness.

[0032] Taking the transfer of a microcentrifuge tube with a specification of 0.5 ml as an example, the transfer plate is implemented as follows:

[0033] The transfer plate is 120mm long, 15mm wide and 5mm high;

[0034] Upper track 1 is 120mm long, 3mm wide and 5mm high;

[0035] The lower track 6 is 120 mm long, 2 mm wide and 5 mm high;

[0036] The distance between the upper track 1 and the lower track 6 is 10 mm, and the centrifuge tube slot slider 4 can slide between the upper track 1 and the lower track 6;

[0037] The centrifuge tube slot slider 4 is 9 mm long, 6.5 mm wide and 3 mm high;

[0038] The inner groove diameter of the centrifuge tube slot slider 4 is 7mm and the height is 5mm;

[0039] The adjustment rod 10 is a T-shaped rod with specifications of 4mm*1.5mm (diameter of the head*height of the head)+2mm*9mm (diameter of the lower part*height of the lower part);

[0040] The elastic silicone strip 5 has a length of 75 mm.

[0041] Under the action of external force, the adjusting rod 10 slides on the handle slider 9 to control the distance between the elastic silicone strip 5 connected to the adjusting rod 4 and the centrifuge tube slot slider 4, that is, to control the size of the centrifuge tube slot.

[0042] The microcentrifuge tube is fixed in the groove of the centrifuge tube slot slider 4 under the action of the slot silicone 3 and the elastic silicone strip 5. Due to the anti-slip properties of the silicone, the microcentrifuge tube is fixed in the groove of the centrifuge tube slot slider 4 and will not slide up and down.

[0043] By adjusting the distance between the handle sliders 9 on both sides of the transfer plate, the connecting springs 2 between the centrifuge tube slot sliders 4 on the transfer plate and the handle springs 7 between the centrifuge tube slot sliders 4 and the handle sliders 9 will expand and contract accordingly, thereby adjusting the distance between the centrifuge tube slot sliders 4. At this time, the adjustment rod 10 can correspondingly slide within the movable groove 11 of the lower track 6. The adjustable transfer plate can be used with various conventional microcentrifuge tube racks and centrifuge tube boxes.

[0044] The size of the adjustable microcentrifuge tube transfer plate is used to further understand the present invention and does not constitute a limitation to the present invention.

[0045] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
