Problems solved by technology

[0010] When processing and testing batches of samples, the time requirements are often tight, the number of samples is large, and the operation is "inconvenient", which will greatly reduce the experimental efficiency, easily cause human error, reduce the accuracy and precision of the experiment, and reduce the experimental results. Therefore, it is urgent to equip corresponding "composite brackets" to greatly shorten the time consumed in the sample processing process, greatly improve the efficiency of sample processing, improve the accuracy and precision of test results, and avoid sample sequence errors man-made accident

Embodiment Construction

[0021] The present invention will be further clarified through the detailed description of specific embodiments below in conjunction with the accompanying drawings, but it is not intended to limit the present invention, but only for illustration.

[0022] The composite bracket of the present invention is composed of a circular base 9, a central shaft 1 fixed on the base 9 and a rotating bracket sleeved on the central shaft 1, and the rotating bracket can rotate around the central shaft 1. There are five layers of circular plates from the bottom to the top on the rotating support, and six circular through holes 6 are uniformly perforated on each circular plate according to the same radius, wherein the first layer 8 and The through hole of the fifth layer 3 is identical and slightly smaller, so that the fixed round bottom flask and the separating funnel, the outside of each through hole of the fourth layer plate 4 and the fifth layer plate 3 respectively have a groove 2, so that ...

Abstract

The invention provides a composite bracket. The bracket comprises a pedestal, a central shaft and a rotary bracket, wherein the central shaft is fixed on the pedestal; the rotary bracket is sleeved on the central shaft, is provided with multiple layers of plates and can rotate around the central shaft; and each layer of plate is provided with a plurality of through holes. The composite bracket of the invention can effectively fix a separating funnel, a round bottomed flask or a glass funnel, so that convenience is brought to batch processing of analysis samples, the experiment is quickened, the working efficiency and the accuracy and the precision of the detection result are improved, the error operation caused by an incorrect sequence of the samples is prevented and the area occupied by an experiment table is saved.

Description

technical field [0001] The invention relates to a composite bracket, in particular to a composite bracket of a separating funnel, a round bottom flask and a glass funnel, wherein the separating funnel, the round bottom flask and the glass funnel can be freely rotated and positioned. Background technique [0002] (1) Separating funnel is a special glass instrument used to extract, purify and separate mixed liquid samples, and it is one of the most commonly used glass instruments in chemical inspection and testing laboratories. [0003] The separatory funnel is composed of a cover (plug), a bucket body and a piston switch at the lower mouth of the bucket body. It is made of ordinary glass and has pear-shaped, spherical and cylindrical shapes. It has become the most widely used and most common one with the functions of uniform extraction and mixing, purification, thorough separation and convenience. The main specifications of the separatory funnel are generally 60mL, 125mL, 25...
