Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of centrifugal liquid extraction, and specifically relates to a convenient operation tool for supernatant extractor. BACKGROUND

[0002] Centrifugal liquid extraction is mainly based on the different settling speeds of different substances in a centrifugal field due to differences in density, mass, etc., thereby realizing separation of liquid components. In the centrifugal process, the mixture is placed in a high-speed rotating centrifuge, and is subjected to a strong centrifugal force, so that the heavier components (such as solid particles and liquid with a larger density) settle to the bottom of the centrifuge tube, while the lighter components (such as liquid with a smaller density) remain in the upper layer, thereby realizing separation.

[0003] At present, the commonly used extractors based on the principle of a syringe are prone to secondary mixing and contamination of the separated liquid during actual experimental operation, because the centrifugal liquid is in a liquid state and has strong self-flowing property and is unstable. In addition, it is difficult for the experimental personnel to maintain the level of supernatant during operation. The experimental personnel have great difficulty in extraction and the operation is troublesome. Moreover, unnecessary mixed liquid other than supernatant is easily extracted, which affects the experiment.
