Background

In the experiment, various glass instruments are used, and whether the glass instruments are clean or not directly influences the accuracy of the experiment result, so the glass instruments need to be cleaned before the experiment. General glass instruments such as beakers, flasks, erlenmeyer flasks, test tubes, measuring cylinders and the like can be brushed with water from the outside to the inside with a brush, so that water-soluble substances, partially insoluble substances and dust can be brushed off; if there are organic substances such as oil stain, it can be washed with detergent powder, soap powder or detergent. Scrubbing with a brush dipped with cleaning powder or detergent, then washing with tap water, and finally rinsing the inner wall with distilled water or deionized water for 2-3 times. The inner wall of the cleaned glassware should be uniformly wetted by water without water streaks and without water droplets. In organic experiments, a ground glass instrument is often used, care should be taken to protect the ground during washing, and a detergent is not suitable for use instead. For glass instruments which are not easily brushed or cleaned with a brush, such as a burette, a volumetric flask, a pipette, etc., usually, a detergent is poured or sucked into a container for soaking for a period of time, then the detergent in the container is poured into a storage bottle for standby, and then the container is rinsed with tap water and deionized water. The sand core glass filter is required to be cleaned immediately after being used, the solid precipitated on the surface of the sand core of the filter is firstly dissolved by adopting a proper detergent aiming at different precipitates remained in the sand core of the filter, then the precipitates remained in the sand core are completely extracted and washed by using the detergent repeatedly by a decompression extraction and washing method, and then the sand core glass filter is cleaned by using distilled water, dried at the temperature of 110 ℃ and stored in a dustproof cabinet.
