Portable loader for micropipette tip box

Abstract

The invention discloses a portable loader for a micropipette tip box. The portable loader comprises a box body, and an upper-layer plate, a fan and a lower-layer plate which are arranged in the box body, wherein the top of the box body is provided with an openable and closable tip inlet, the upper-layer plate is fixed below the tip inlet, the lower-layer plate is arranged below the upper-layer plate, and the fan is fixedly arranged above the lower-layer plate on the box body. The portable loader adopts a simple physical principle, and tips are arranged in transverse slotted holes of the lower-layer plate of the loader by setting the wind speed of the fan, so that the loading efficiency of tips used in a laboratory can be greatly improved, and the labor intensity of operators is reduced by convenient and quick loading. The contamination probability of the tips can be reduced by virtue of the loader. The loader has a simple structure, is easy to process, has a small size, is convenient to operate, can save a space for the laboratory, is also suitable for loading of other tips with various sizes, and can be widely popularized and used.

Description

technical field [0001] The invention belongs to the field of biomedicine and medical experiment equipment, and in particular relates to a portable loader used for a tip box of a micropipettor. Background technique [0002] In the development process of biological science, biological experiments are developing more and more towards the microscopic direction, and research at the molecular level is essential. Modern life science research based on experiments such as molecular biology, cell biology, and biochemistry puts forward higher requirements for experimental accuracy and experimental conditions, especially for solution operations, which put forward a series of special requirements, namely: sterility, Ultra-trace amount, high precision. Volumetric vessels such as measuring cups, cylinders, and pipettes commonly used in chemical experiments cannot meet the above requirements. Therefore, the micropipette, that is, the "pipette gun", has become an indispensable experimental...

AI Technical Summary

Problems solved by technology

[0003] In biomedical laboratories and other medical laboratories, pipettes are used more and more widely, and the frequency of use is higher and higher, and the pipette tip is a key part of the pipette, and it is used in large quantities in experiments. ;The pipette tips are packaged in loose parts when they leave the factory. After the scientific research institutions or laboratories purchase them, they need to be manually packed into the corresponding pipette tip boxes, which leads to low packing efficiency of the pipette tips; although the experimental pipette tips There are different specifications, but the volume is very small, and the mass is less than 0.3g. Manual boxing is cumbersome and time-consuming, which affects the progress of the work.

[0004] At present, there are related products in Japan, but they have not been promoted due to their high price and bulky volume; the existing technologies are not fully mature, and no practical products have entered the market

The problem is that the stability and feasibility are relatively poor. In the patent 200620078982.7, an auxiliary device for swinging the tip of the micro-dosing gun is disclosed. It is composed of a plurality of parallel support rods and sliding rods. Placement, the slide bar is used to line up the gun heads. This device is mainly aimed at the arrangement of the gun heads, but how to collect the gun heads has not been solved

In the patent 201020673207.2, an intelligent sensing and transmission device is disclosed. Although the intelligent sensing and transmission system is used to increase the technological content, the processing process is more difficult, especially for small objects such as gun heads, which increases the Increased the difficulty of manufacturing products and increased production costs
