Description

Technical Field

[0001] This utility model relates to experimental instruments, and more particularly to a centrifuge with a combined housing structure. Background Technology

[0002] Centrifugation utilizes the powerful centrifugal force generated by the high-speed rotation of a centrifuge rotor to accelerate the sedimentation rate of particles in a liquid, separating substances with different sedimentation coefficients and buoyant densities in a sample. Patent document CN206064642U discloses a centrifuge comprising a base, a casing mounted on the base, a cover that can be opened or sealed and fastened to the top of the casing, a reaction tank rotatable about its own axis and disposed within the inner cavity of the casing, and a feed pipe extending axially through the cover and inserted into the reaction tank. The reaction tank includes an inner drum and an outer drum. The outer peripheral wall of the inner drum has filter holes communicating with the inner cavity of the outer drum. The outer drum has a chamber with an opening at its top, and the diameter of the outer drum gradually decreases from top to bottom. The reaction tank also includes a filter element disposed within the inner cavity of the inner drum. During the use of a centrifuge, due to its high rotational speed, if the rotor or reagent container becomes loose, the detached parts possess significant impact force. Furthermore, the centrifuge's positioning structure is not sufficiently stable, making it prone to detachment in such situations, posing a threat to the safety of the experimenter. Therefore, it is necessary to optimize the structure of this centrifuge to overcome these shortcomings. Utility Model Content
