Embodiment 1

[0022] Such as Figure 1-3 As shown, a modular assembly type pipette tip box includes a box cover 1, a box bottom 2 and a bracket partition, the box cover 1 is directly vertically buckled to the box bottom 2, and the bracket partition is mainly composed of at least two Of course, these bracket partition modules can include bracket partition modules 3 with the same height, or all of them can be composed of bracket partition modules of different heights;

[0023] Each bracket partition module 3 has the same width, and this width is adapted to the width of the box bottom 2, so that each bracket partition module 3 is assembled in the box bottom 2 and is clearance fit with the box bottom 2. There are through holes distributed on the surface of the plate module 3 opposite to the top surface of the box cover 1, and the specifications of the through holes distributed on the surface of the at least two bracket partition modules 3 with different heights are different. The specification...

Embodiment example 2

[0036] The technical solution is the same as that of Example 1, except that this example involves PCR amplification (25 μL / tube). The following table is a statistical table of the number of pipette tips used during the experiment.

[0037]

[0038]

[0039] In this experiment, the amplification primers are the same and the 10 templates are different to calculate the number of pipette tips 5. The yellow tips are roughly equal to the white tips, and a large bracket spacer for holding the yellow tips can be used. The plate module 31 and the large bracket partition module 32 for holding the tip of the white gun are combined in equal proportions, and the number of the bracket partition modules is selected according to the number of PCR manifolds.

Embodiment 3

[0041] The technical scheme is the same as that of Example 1, the difference is that this embodiment relates to an experiment of extracting total RNA from suspension cells, and the following table shows the number of pipette tips used in each operation in the experimental process of extracting total RNA from suspension cells (Trizol method) statistics table.

[0042]

[0043] Based on the calculation of 4 samples in one experiment, a total of 24 blue pipette tips, 32 yellow pipette tips and 20 white pipette tips were used in this experiment, and a large bracket partition module 33 for holding blue pipette tips can be selected , a large support partition module 31 for holding the yellow tip and a large support partition module 32 for holding the white tip.

Abstract

The invention provides a module assembling type pipette tip box, belongs to the field of auxiliary equipment of biochemical instruments, and aims to solve the technical problems that a number of pipette tips with different specifications cannot be allocated according to experiment needs and cannot be compatible with the tip box in the prior art. The module assembling type pipette tip box is technically characterized by comprising a box cover, a box bottom and a support partition board assembly, wherein the box cover is buckled at the box bottom; the support partition board assembly comprises at least two support partition board modules with different heights, the support partition board modules are assembled in the box bottom, through holes are distributed in one surface, opposite to the top surface of the box cover, of each support partition board module, and the specifications of the through holes distributed in the surfaces of the at least two support partition board modules with different heights are different. The module assembling type pipette tip box has the benefits as follows: the use number of the pipette tip boxes is reduced, so that the module assembling type pipette tip box is particularly applicable to experiment operation performed in narrow space, and great convenience is brought to experiments.

Description

technical field [0001] The invention belongs to the field of biochemical instrument auxiliary equipment, and relates to a pipette tip box. Background technique [0002] In the traditional pipette tip box, a box can only accommodate one type of tip, and the number of tips that can be accommodated is fixed. Now the main structure of the pipette tip box on the market is a box cover, a box bottom and The bracket partition in the middle, a pipette tip box is only used to fix one kind of partition board, and the through holes of different sizes are evenly distributed on the partition board. The diameter of the round hole is divided into three categories, which determines the type of inserted pipette tip (1mL, 200μL, 10μL), the common ones are 60 tips in a 1mL box, 96 tips in 200μL, and 96 tips in 10μL. [0003] In biochemical, molecular or cell experiments, the number of different types of pipette tips used by experimenters may vary greatly, that is, there is an imbalance in the ...
