Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a Qubit detection tube fixing bracket. Background Art

[0002] Qubit assay tubes are commonly used in molecular laboratories. They are highly effective tools for measuring nucleic acid and protein concentrations, widely used in clinical laboratories and research settings. They are compatible with the Qubit Fluorometer. These assay tubes offer high sensitivity and accuracy, enabling rapid and precise measurement of nucleic acid or protein concentrations in samples. Qubit assay tubes are 0.5mL thin-walled polypropylene tubes designed for use with the Qubit Fluorometer.

[0003] In the existing technology, the components of the Qubit detection kit are divided into Reagent, Buffer, Standard 1 and Standard 2 or 1x Working Solution, Standard 1 and Standard 2. Currently, when laboratories use the Qubit instrument to detect sample concentration, they first place the 0.5mL test tube on the 96-well plate, then use a single-channel pipette to add the test working solution to the corresponding test tubes one by one, and then use a single-channel pipette to add the samples to be tested to the corresponding tubes in sequence.

[0004] However, when there are many samples to be tested, the experimental operation time is relatively long, and it is easy to add the wrong wells when using a single-channel pipette. In addition, when preparing the Reagent and Buffer mixture, they need to be placed in 1.5mL centrifuge tubes and 15mL centrifuge tubes. At this time, two specifications of centrifuge tube racks are needed, which makes the experimental operation table messy and crowded. Utility Model Content

[0027] Example 2

[0028] See also Figures 1 to 4On the basis of embodiment 1, in order to realize the rotation and storage of the support rod 8, the limit groove 4 is a square groove, and the four limit grooves 4 are symmetrically distributed. The surface of the limit groove 4 is fixedly connected with a plug 5, which consists of a square block and a semicircular rubber plug. The bracket body 1 is away from the limit groove 4. The surface of the end surface is provided with a receiving groove 11 on both sides. The receiving groove 11 is a square groove. The surface of the receiving groove 11 is fixedly connected with an axis rod 12 on both sides. The axis rod 12 is a cylindrical structure. The axis rod 12 passes through the circular hole on the surface of the support rod 8. The support rod 8 is a square block structure. The width of the support rod 8 is less than the groove depth of the receiving groove 11. Rubber grooves 19 are provided on both sides of the surface of the support rod 8. The surface of the rubber groove 19 is fixedly connected with a rubber block 13. When the rotating support rod 8 is in a vertical state with the bracket body 1, the rubber block 13 is pressed from The retracted state is restored to its original state, and the baffle 14 is popped out of the rubber groove 19 and overlapped on the surface of the bracket body 1, so that the support rod 8 can no longer rotate and move. When the support rod 8 needs to be stored, the baffle 14 is pressed into the rubber groove 19, and one end of the inclined surface of the baffle 14 is squeezed by the surface of the storage groove 11 and gradually retracted into the rubber groove 19. At this time, the rubber block 13 changes from the original state to the compressed state, and the rubber pad 15 on the surface of the baffle 14 is clamped on the surface of the storage groove 11 to prevent the support rod 8 from escaping from the storage groove 11. The other end of the rubber block 13 is fixedly connected to the baffle 14, and the ends of the two baffles 14 away from each other are provided with an inclined surface. The surface of the end of the baffle 14 away from the rubber block 13 is fixedly connected to the rubber pad 15, and the baffle 14 overlaps the surface of the bracket body 1 to limit the support rod 8.

The surface of the sliding hole 17 is provided with a threaded groove 18. The extension rod 9 is a circular plate-shaped structure with a cross section of “T”. The surface of the extension rod 9 is provided with a threaded portion 16. The threaded portion 16 and the threaded groove 18 are matched and connected with each other. By rotating the threaded groove 18 and the threaded portion 16, the extension rod 9 can be slid out or retracted from the surface of the support rod 8, thereby adjusting the height of the support body 1. The sliding hole 17 is fixedly connected to the limit block 10 on the end surface away from the support rod 8. The limit block 10 is a square block structure. The surface of the limit block 10 is provided with a plug hole 7. The plug hole 7 consists of a square groove and a semicircular groove.

[0031] In actual use, first, manually push the multiple support rods 8 outward from the storage grooves 11. At this time, the rubber block 13 squeezed in the rubber groove 19 rebounds, and the baffle 14 pops out and presses against the surface of the bracket body 1. At this time, the multiple support rods 8 are vertically distributed with the bracket body 1. Then, the extension rod 9 is rotated to a suitable length and placed on the workbench. The test tubes are placed in hole position 1 2 in turn, and the working liquid and the sample to be tested are added to the test tubes in turn through an eight-channel pipette.

At this time, the limit block 10 in the limit groove 4 The plug block 5 fits tightly with the plug hole 7 on the surface of the limit block 10, so that multiple bracket bodies 1 can be stacked, thereby reducing the occupied space. When the support rod 8 is not needed, press the baffle 14 by hand to retract the baffle 14 into the rubber groove 19, and the support rod 8 can be rotated into the storage groove 11. At this time, the rubber pad 15 on the surface of the baffle 14 is clamped between the storage groove 11 and the baffle 14 to prevent the support rod 8 from being displaced. When there are many samples to be tested, a 15ml centrifuge tube can be configured with a mixture of Reagent and Buffer, and then an eight-channel pipette can be used to add the mixture to the 0.5mL test tube on the fixed rack.
