Description

Universal mouth pipette assembly

The present invention relates to a universal mouse pipette assembly, and more particularly, to a universal mouse pipette assembly, which includes a universal adapter capable of mounting a Pasteur pipette or various micropipettes, to save time and money when moving cells and materials. will be.

Pipettes are thin tubes of glass or plastic used for measuring or dispensing liquids. Common uses include mespipettes (hole pipettes), dropper pipettes, Pasteur pipettes and automatic pipettes.

The mespipette is used to measure any amount of liquid. The mespipette is engraved with a fine scale between the maximum capacities and the hole pipette does not have such a small scale, so it is used to measure a certain volume more accurately.

In addition, the dropper pipette is a type of liquid dropping with a rubber dropper, which is less accurate than a mesopeater but is used when repeating the same tissue with one hand such as dispensing a medium or transferring cultured cells. In addition to incubation, it is convenient for handling relatively small amounts of liquids (eg, sucking samples or washing samples).

Pasteur pipettes are tapered ends of glass tubes that are sucked in with rubber droppers. This pipette is not intended for weighing purposes, but for handling small amounts of liquids. It is cheap and can be discarded after use. It is mainly used for the purpose of avoiding mixing of samples.

In addition, an automatic pipette means that a tip (tip) for sucking liquid is attached to a body equipped with a suction part and a measurement (scale) part. The scale part and the suction part are interlocked, and there is a type capable of sucking an arbitrary amount of liquid by operating a digital scale and a type in which a certain amount is set. Automated pipettes are widely used in experiments that handle proteins and nucleic acids that require high levels of precision because they can accurately measure traces of liquids in microliters and have little liquid adhesion to the tips.

In addition, according to the magnitude | size of the volume to measure, a micro pipette for what is used for a small quantity and an ultra-small pipette for what is a small quantity are called.

On the other hand, in the field of biotechnology, various experiments using an egg or fertilized egg have been conducted, and various types of pipettes are used to move cells and / or test substances such as fertilized egg.

In such tests, it is necessary to selectively use Pasteur pipettes or micropipettes in the movement of cells and / or test substances. When using these various types of pipettes, the pipette assembly needs to be replaced. Therefore, various pipette assemblies have to be provided, and there is a problem in that the pipette assembly needs to be time-consuming and expensive.

In addition, there was a risk of cross infection by pipettes when moving various cells and test substances.

In the background of the present invention, Korean Patent No. 10-0712602 describes a micropipette for nucleus removal of an egg.

The pipette holder 132 is formed in a tubular shape, one end of which is coupled to the mouth pipette assembly 100 including the mouthpiece 110 and the tube 120, and the end of the Pasteur pipette is forcibly fixed to the other end thereof. . The pipette holder 132 is not particularly limited in material if the end of the Pasteur pipette can be coupled, the elastic member may be suitable.

The stopper 134 opens and closes the distal end of the pipette holder 132, and a through hole 136 is formed at the center of the stopper 134 so that an end of the micropipette may be inserted and supported.

The stopper 134 has a protrusion extending into the pipette holder 132, and the through hole 136 is formed in the stopper 134 in a conical shape narrowing into the pipette holder 132. Can be. Among the ends of the conical through hole 136 as described above, the end into which the micro pipette is inserted is wide. Therefore, various sizes of micro pipettes (microcapillary tube, 1-200 ul) can be easily mounted on the stopper 134 and used. Also, the other end of the conical through hole 136 is narrow. Therefore, the micro pipette once inserted is stably supported within the pipette holder 132 by the elasticity of the stopper 134.

According to another aspect, a general purpose mouse pipette assembly 100 is provided, comprising the universal adapter 130 for the pipette assembly described above.

That is, the mouse pipette assembly 100 includes a mouthpiece 110; A tubular tube 120 connected to one side of the mouthpiece 110; And the universal adapter 130 provided at the end of the tube 120.
