Problems solved by technology

For the use of traditional centrifuge tubes, on the one hand, the one-handed cap opening method is mainly used, that is, to hold the centrifuge tube with one hand and open it with the index finger and thumb. When opening the cap, the cap is easily contaminated by gloves
In addition, since only one centrifuge tube can be opened at a time, frequent opening and closing of the cap is very tedious and easy to contaminate the sample when performing such things as plasmid extraction and RNA and DNA extraction, and it is also difficult to open and close the cap individually for each centrifuge tube. very time consuming
On the other hand, after the traditional centrifuge tube is centrifuged, the sediment is very easy to be taken out when absorbing the supernatant, especially when the centrifugal force is not high
Therefore, when conducting experiments such as flow cytometry that require frequent centrifugation operations, due to repeated centrifugation to remove the supernatant, the loss of the final cell and other pellets is very large

Embodiment 1

[0015] figure 1 Describes a centrifuge tube according to the present invention which is anti-pollution, high-throughput uncapped and easy to separate and precipitate. It includes a tube body 1 and a tube cover 2 matched with the tube body. The bottom of the tube body 1 is provided with an inclined surface, so that The sediment concentrates at the bottom of the slope. The tube cover 2 adopts a U-shaped cap head, which can be opened with a matching cover opener, thereby avoiding contact between gloves and the centrifuge tube mouth, and preventing the liquid in the centrifuge tube from being polluted.

Embodiment 2

[0017] figure 2 A centrifuge tube with anti-pollution, high-throughput decapping and easy separation of precipitates according to the present invention is described. Tube cap a adopts a U-shaped cap head, which can be opened with a matching cap opener, so as to avoid contact between gloves and the mouth of the centrifuge tube and prevent the liquid in the centrifuge tube from being polluted. In this embodiment, the matching cap opener b can open 8 centrifuge tube caps at the same time, so as to realize high-throughput sample operation.

Abstract

The invention provides a centrifugal tube capable of preventing pollution, realizing high-flux uncovering and facilitating separation and precipitation. The centrifugal tube comprises a tube body anda tube cover. The centrifugal tube is characterized in that an inclined surface is arranged at the bottom of the tube body so that precipitates are concentrated at the bottom of the inclined surface during centrifugation; and a cap head is connected to one side of the tube cover, wherein the side is positioned at the outer part when the tube cover is in a closed state, and extends to form a U shape or a similar U shape with one part of the tube cover.

Description

technical field [0001] The invention generally relates to the field of experimental sample processing, and more specifically relates to a centrifuge tube with anti-pollution, high-throughput cap opening and easy separation and precipitation. Background technique [0002] Centrifuge tubes are the most common consumables widely used in laboratory sample processing. For the use of traditional centrifuge tubes, on the one hand, the one-handed cap opening method is mainly used, that is, to hold the centrifuge tube with one hand and open it with the index finger and thumb. When the cap is opened, the cap is easily contaminated by gloves. In addition, since only one centrifuge tube can be opened at a time, frequent opening and closing of the cap is very tedious and easy to contaminate the sample when performing such things as plasmid extraction and RNA and DNA extraction, and it is also difficult to open and close the cap individually for each centrifuge tube. Very time consuming....
