Problems solved by technology

The use of this centrifuge tube in some cases will bring very inconvenient content, such as when there are few solid phase substances, it is often difficult or even impossible to get it from the pouring liquid end; in addition, sometimes due to Usually, the area of ​​the bottom of some centrifuge tube conical tubes is too large, and the solid phase substances are not easy to be concentrated.
In this way, this will affect the acquisition, detection, analysis, etc. of the subsequent sediment

Abstract

The invention relates to a special bottom opening centrifuge tube device. The special bottom opening centrifuge tube device comprises a common centrifuge tube part with a small straight pipe bottom opening assembly and a bottom opening sealing cover, and is characterized in that a conical pipe lower end of the common centrifuge tube part with the small straight pipe bottom opening assembly is provided with a small straight pipe, and a lower end opening of the small straight pipe is connected with the bottom opening sealing cover. A method and the device disclosed by the invention are easy to operate, concentrated gathering of centrifugal separation solid-phase objects is easy, centrifugate is convenient to collect, and the accuracy of analysis on the centrifugate is greatly improved.

Description

technical field [0001] The invention relates to a detection device for centrifuging and collecting sediment, in particular to a device for obtaining trace sediment. Background technique [0002] Centrifugation is a commonly used method for separating solid phase substances from mixed liquid phases. The centrifuge tubes currently used in centrifugation are usually centrifuge tubes with a tapered bottom that is directly closed, and the method of taking out the separated solid phase material is usually obtained from the pouring liquid end of the centrifuge tube. The use of this centrifuge tube in some cases will bring very inconvenient content, such as when there are few solid phase substances, it is often difficult or even impossible to get it from the pouring liquid end; in addition, sometimes due to Usually, the bottom area of ​​some centrifuge tube conical tubes is too large, and the solid phase substances are not easy to be concentrated. In this way, this will affect the...
