Description

A New Separation Centrifuge Tube

technical field

The utility model belongs to the field of medical experiment equipment, in particular to a novel separated centrifuge tube.

Background technique

Now with the continuous development of social economy, the current level of scientific and technological research is also constantly improving. The centrifuge tube is a kind of equipment commonly used in medical and biological experimental research. The tubular sample container can be equipped with a sealed cover or a gland.

The general centrifuge tube devices that appear on the market now are composed of a simple tube body and cap structure. Although this design reduces the production cost, the separation effect is poor, especially in the research and medical experiments of some traditional Chinese medicine. The tube structure can only achieve preliminary filtration during liquid centrifugation, but is not suitable for DNA purification and concentration. The cell separation is insufficient, the recovery rate is low, and it is not convenient for further product experiments. At the same time, it will affect some important DNA research processes. Moreover, the bottom of the current centrifuge tube has a conical structure. Since cells often need to transfer the separated substances in the centrifuge tube when they are separated, the amount of separated substances in the centrifuge tube is extremely small, which causes waste when transferring.

Utility model content

The purpose of the utility model is to provide a new type of separation centrifuge tube, aiming to solve the problem that the existing centrifuge tube is not convenient to transfer the separated cell matter.

The utility model is achieved in that:

A new type of separated centrifuge tube, including a centrifuge tube body, the centrifuge tube body includes a first tube body and a second tube body, the bottom of the first tube body is provided with a base, and the diameter of the mouth of the base is smaller than that of the bottom diameter, and the side wall of the base is an arc-shaped structure, the inside of the side wall of the first pipe body is uniformly provided with positioning protrusions, the outer wall of the second pipe body is provided with a flange, and the bottom of the second pipe body A filter film is provided, the positioning protrusion and the flange cooperate with each other, and the mouth of the first pipe body is connected with a cap.

Preferably, the nozzle portion of the first pipe body is provided with a sealing ring.

Preferably, the side wall of the first pipe body is provided with scale markings.

Preferably, the base is screwed to the bottom of the first pipe body.

Preferably, the diameter of the second pipe body is smaller than that of the first pipe body.

technical effect

The utility model provides a new type of separated centrifuge tube, through the base structure provided on the device, the base after centrifugation is separated from the first tube body, so as to avoid waste and separation when the material in the centrifuge tube is transferred. The final material loss makes most of the centrifuged material on the base, and the bottom of the base is set as a large observation area, which is also convenient for experimental researchers to observe.
