High-temperature-resistant centrifugal tube capable of being used for rapid separation and drying, and using method thereof

Abstract

The invention provides a high-temperature-resistant centrifugal tube capable of being used for rapid separation and drying. The structure of the high-temperature-resistant centrifugal tube comprises atube cover and a tube body from top to bottom, wherein internal threads are arranged in the tube cover, external threads matched with the internal threads of the tube cover are arranged at the upperend of the tube body, the tube cover can be screwed on the tube body, the tube body is made of polyethylene tetrafluoride (PTFE), has high temperature resistance and corrosion resistance and can stably work at a temperature of 260 DEG C or below, and the tube cover is made of polyethylene tetrafluoride (PTF). According to the high-temperature-resistant centrifugal tube capable of being used for rapid separation and drying and the using method, the centrifugal tube is resistant to high temperature and corrosion, light in weight and low in manufacturing cost, can be used for rapid separation ofturbid liquid and rapid drying of centrifuged sediments, greatly improves the accuracy and efficiency of experiments and has good application value.

Description

technical field [0001] The invention belongs to the field of experimental equipment, and in particular relates to a high-temperature-resistant centrifuge tube which can be used for rapid separation and drying and a use method thereof. Background technique [0002] The centrifuge tube is a commonly used experimental equipment in the laboratory, which can be used for the separation of the suspension. The principle is to use the centrifuge tube to rotate at a high speed in the centrifuge. The bottom of the tube, so as to realize the rapid separation of substances. Laboratory centrifuge tubes are usually made of polyethylene (PE), polycarbonate (PC), polypropylene (PP) and other materials. The melting point of centrifuge tubes made of these materials is generally below 150°C, and the melting point is relatively low. [0003] In daily laboratory experiments, it is sometimes necessary to take out the precipitate at the bottom of the centrifuge tube after centrifugation, place the...

Problems solved by technology

However, the melting point of the centrifuge tube is low, and the drying temperature should not be too high during drying. Usually, it can only be adjusted to 40-60°C, so the drying time of the sample will be very long. When the water content of the sample is too high, it may even take 1- 2 days, which seriously affects the experimental efficiency, so it is necessary to develop a high temperature resistant centrifuge tube, increase the drying temperature and shorten the drying time
