Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] Such as figure 1As shown, a density gradient preparation device includes a liquid injector 5 and a centrifuge tube 7. The liquid injector 5 cooperates with the centrifuge tube 7, and also includes a support frame 1, a fixed frame 3, and a fixed box 5. The fixed frame The two ends of 3 are slidably matched with the support frame 1, and the fixed frame 3 is provided with a plurality of fixing holes 301 matching with the liquid injector 4, and the fixed bo...

Abstract

The invention discloses a density gradient preparation device. The device comprises an injector, centrifugal pipes, a support, a fixed frame and a fixed tank, wherein the injector is matched with thecentrifugal pipes; two ends of the fixed frame are in sliding fit with the support; a plurality of fixed holes matched with the injector are formed in the fixed frame; the fixed tank is arranged underthe fixed frame; a supporting plate is arranged in the middle of the fixed tank, and is provided with a plurality of supporting holes; an assembly plate is arranged at the bottom of the fixed tank inan inclined manner; a placing hole is formed in the assembly plate; the centrifugal pipes are arranged in the supporting holes, and the bottoms of the centrifugal pipes are matched with the placing holes; and ice cubes are arranged in the fixed tank, and are arranged under the supporting plate. According to the device, a plurality of density gradients can be prepared simultaneously in one time, the work efficiency is greatly improved, labor is saved, experimental fatigue is relieved, and fixing is reliable.

Description

technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a density gradient preparation device. Background technique [0002] Organelles are micro-organs with specific morphological structures and functions in the cytoplasm. The organelles in cells mainly include: mitochondria, endoplasmic reticulum, centrosomes, chloroplasts, Golgi apparatus, ribosomes, etc. They make up the basic structure of cells and enable cells to work and run normally. Organelles play an important role in sustaining life activities. For example, mitochondria are the "power factory" of cells and the main place for cells to perform oxidative phosphorylation and synthesize ATP. Mitochondria not only improve energy for cells, but also participate in such things as cell differentiation and cell information. Transmitting and cell apoptosis and other processes, and has the ability to regulate cell growth and cell cycle; chloroplast is a unique ...
