Description

Simple device convenient to detach centrifuging tube bottom sediment

Technical Field

The utility model relates to the technical field of centrifuge tube cleaning, in particular to a simple device convenient for removing sediment at the bottom of a centrifuge tube.

Background

Centrifugation is a method of separating, concentrating, and purifying a sample by utilizing the difference in sedimentation coefficient or buoyancy density of a substance by centrifugal force of a rotational motion. The centrifuge tube is one of the necessary laboratory vessels in the laboratory of biochemistry, food detection and the like, is a container for separating, concentrating and purifying samples to be detected, and belongs to the parts and accessories of the laboratory centrifuge. Centrifuge tubes can be classified into three types, conical, flat bottom and round bottom according to the shape of the bottom, wherein conical centrifuge tubes are the most used type of centrifuge tubes in the laboratory; the centrifugal tube can be divided into a plastic centrifugal tube and a steel centrifugal tube according to the material. The plastic centrifuge tube is transparent or semitransparent, and is made of materials with better performance, such as polypropylene (PP), but is easy to deform, poor in organic solvent corrosion resistance and short in service life; the steel centrifuge tube has high strength, no deformation, heat resistance, freezing resistance and chemical corrosion resistance, but high cost.

In food testing and analysis laboratories, conical plastic centrifuge tubes are commonly used to reduce testing costs. Under the high-speed rotation of the centrifugal machine, the conical plastic centrifugal tube filled with the suspension of the sample to be detected enables suspended tiny particles (solid samples, inorganic salts, adsorbents, purifying agents and the like) to settle at a certain speed due to the action of huge centrifugal force, so that the solution can be separated, concentrated and purified, and the settling speed of the particles depends on the rotating speed of the centrifugal machine, the mass, the size, the density and the like of the particles.

After the suspension of the sample to be tested in the centrifuge tube is centrifuged, the supernatant is sucked out for standby, and the lower layer of tiny particles (including solid sample, inorganic salt, adsorbent, purifying agent and the like) are gathered at the conical bottom of the centrifuge tube to form sediment, even are coagulated into blocks and are adhered to the conical bottom. The common method for treating the sediment at the bottom of the centrifuge tube is to stretch the long-handle medicine spoon to the bottom of the centrifuge tube for stirring, and then take out the massive sediment. For this purpose we propose a device that facilitates removal of the sediment at the bottom of the centrifuge tube.
