Abstract

The present application relates to an analytical instrument apparatus, and in particular, to a centrifugal driving apparatus and a centrifugal device. The centrifugal driving apparatus comprises a first rotating disc, a second rotating disc, a first transmission mechanism, a second transmission mechanism, and a driving mechanism; the driving mechanism drives the second rotating disc to rotate around its own rotation center; the first rotating disc is rotatably disposed on the second rotating disc, and the first rotating disc is connected to the second transmission mechanism by means of the first transmission mechanism; the first transmission mechanism and the second transmission mechanism can switch between a rotating state and a locked state, so that the first rotating disc rotates or is locked around its own rotation center when rotating synchronously with the second rotating disc. In the present application, the first rotating disc can rotate or be locked when revolving with the second rotating disc. A centrifuge operation is implemented when the first rotating disc only revolves, and a mixing operation is implemented when the first rotating disc revolves and rotates. Mixing and centrifugal separation operations on a sample are completed by means of one machine, saving time and labor, and improving the experiment efficiency.

Abstract

The present application provides a digitizing device and method for a liquid sample. The device comprises: a container provided with at least one digitizing channel for accommodating a liquid sample, the diameter size of the digitizing channel being less than or equal to a preset value to limit diffusion of the digitized liquid sample in the digitizing channel; and a heating assembly at least partially heating the digitizing channel, the heating temperature of the heating assembly being not lower than the cloud point temperature of the liquid sample. According to the technical solution of the present application, after liquid to be digitized is filled into the digitizing channel of a preset size, the digitizing channel is heated at a temperature higher than the cloud point temperature of the liquid sample, so that the digital processing of the liquid sample to be digitized can be realized, and compared with the prior art, the present application is simple and convenient in overall operation, the container, the heating assembly and the like used are conventional instruments with relatively low prices, and the digitizing operation of the liquid sample can be realized in a short time.

Abstract

A device provides selective modes of vibrational oscillations and centrifugal rotations for preparing analysis samples. The device includes a base, an elastic connection body, a group of a synchronous unidirectional bearing inner ring and a synchronous unidirectional bearing outer ring, a group of an eccentric unidirectional bearing inner ring and an eccentric unidirectional bearing outer ring, and a synchronous fixed ring and a motor on the base. The eccentric unidirectional bearing outer ring is connected to a sample plate for holding the analysis samples.

Abstract

An analysis sample preparation device and analysis sample preparation method, comprising: a base (1), an elastic connection body (5), a group comprising a synchronized one-way bearing inner ring (41) and a synchronized one-way bearing outer ring (42), a group comprising an eccentric one-way bearing inner ring (61) and an eccentric one-way bearing outer ring (62), and a synchronized fixed ring (2) and motor (31) provided on the base (1). The eccentric one-way bearing inner ring (61) is fixed to an eccentric shaft (32) extending from the motor (31). The eccentric one-way bearing outer ring (62) is fixed to an eccentric shaft sleeve (9). An integrated body formed from the eccentric shaft sleeve (9), the eccentric shaft (32), the eccentric one-way bearing inner ring (61), and the eccentric one-way bearing outer ring (62) has a center of mass disposed on a line extending from a center line of the motor (31). The eccentric one-way bearing inner ring (61) and the eccentric one-way bearing outer ring (62) can only rotate in direction A, while the synchronized one-way bearing inner ring (41) and the synchronized one-way bearing outer ring (42) can only rotate in a direction opposite to direction A.
