Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube technology, specifically to a laboratory centrifuge tube that is resistant to deformation under high-speed rotation conditions. Background Technology

[0002] Centrifuge tubes are core tools in laboratories for separating, processing, and preserving biological or chemical samples. They are essentially tubular containers that use centrifugal force generated by the high-speed rotation of a centrifuge to achieve the separation and purification of components of different densities in a liquid.

[0003] The core function of centrifuge tubes is physical separation, such as separating plasma from blood cells in clinical testing, or precipitating DNA / RNA in molecular biology experiments. This separation is based on the difference in sedimentation rates of different substances in a centrifugal force field, enabling efficient extraction of target components and removal of impurities.

[0004] Centrifuge tubes are commonly used with centrifuges, primarily for separating trace samples or blood samples. They are generally made of polypropylene (PP), polystyrene (PS), or polycarbonate (PC) and are essential tools for sample processing and preservation in fields such as biochemistry, molecular biology, immunology, botany, and clinical testing. However, the bottom structure of centrifuges may be relatively weak during high-speed operation. Under external impact or the pressure generated by high-speed centrifugation, the bottom is prone to cracking or deformation, which can lead to sample leakage, damage to the centrifugation equipment, and even safety hazards for laboratory personnel. Furthermore, the conical bottom makes it difficult to place centrifuge tubes independently on the lab bench; they require the assistance of tube racks or centrifuge plates to maintain their upright position. Utility Model Content

[0005] The purpose of this invention is to address the issue that the bottom structure of a centrifuge may be relatively weak when it is running at high speed. Under the impact of external forces or the pressure generated by high-speed centrifugation, the bottom is prone to cracking or deformation, which can lead to sample leakage, damage to the centrifugation equipment, and even safety hazards to laboratory personnel.

[0006] A centrifuge tube body is provided, with multiple sidewall support rings fixedly disposed on the side of the centrifuge tube body, and the adjacent sidewall support rings are horizontally arranged.

[0007] As a preferred option, a centrifuge tube base is provided at the bottom of the centrifuge tube.

[0008] As a preferred embodiment, the bottom of the centrifuge tube is conical, and the centrifuge tube base is cylindrical and located on the outside of the conical part.

[0009] As a preferred option, a sidewall support ring is provided on the outside of the centrifuge tube base.

[0010] As a preferred option, a centrifuge tube cap is provided at the top of the centrifuge tube.

[0011] As a preferred embodiment, the centrifuge tube cap is fixedly connected to the upper end of the centrifuge tube body at the shoulder of the centrifuge tube opening, and the shoulder of the centrifuge tube opening is an elastic element.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention features multiple sidewall support rings on the sides of centrifuge tubes. These rings enhance the pressure resistance of the tubes during centrifugation. When liquid exerts pressure on the sides of the tube, the support rings effectively resist this pressure, preventing deformation or breakage of the sides and bottom. Simultaneously, the support rings also serve a positioning function, making the centrifuge tubes more stable within the centrifuge rack and reducing displacement during centrifugation. Furthermore, centrifuge tubes with bases can be placed independently on the lab bench without external force or a centrifuge rack, saving experimental space and facilitating operation by researchers.
