Daily maintenance of glassware of automatic integrated distiller

Daily maintenance of glassware of the automatic integrated distiller Based on the traditional instrument, the automatic integrated distiller integrates the unique design concept, such as uniform heating, volume control distillation end point, anti suction, cooling water circulation cooling and reflux device The integrated universal distiller realizes the purposes of simple operation, beautiful and practical, energy saving and consumption reduction It can be widely used in environmental protection, food detection, disease control, water supply and drainage, universities, scientific research institutes, factories, mines and other laboratories where distillation is required, such as distillation of volatile phenol, ammonia nitrogen, sulfur dioxide and other projects At present, more and more users begin to choose the integrated distiller for sample pretreatment distillation, so how to maintain the operation of the instrument in use?
The automatic integrated distiller is composed of six heating units When washing the glassware, you should first wash your hands, so as not to attach the oil on your hands to the instrument and increase the difficulty of washing For general all glass distillers, such as beakers, flasks, conical bottles, test tubes and measuring cylinders, you can brush them with water from the outside to the inside, so that the water can be washed away Soluble substances, some insoluble substances and dust If there is any organic matter such as oil stain, it can be soaked in a certain concentration of detergent solution for a certain period of time, then it can be scrubbed with a brush dipped in detergent, then it can be washed with tap water, and then the inner wall can be moistened with purified water for 2-3 times The inner wall of the cleaned glassware shall be able to be evenly wetted by water without water streaks and without water drops The glass instrument with grinding mouth is often used, and the grinding mouth shall be protected when washing The glass distilling utensils shall be cleaned immediately after use According to the different precipitates left in the sand core of the filter, appropriate detergent shall be used to dissolve the solid precipitated on the surface of the sand core first, and then the residual precipitates in the sand core shall be repeatedly washed out with detergent by decompression pumping method, and then washed with distilled water Glass instrument with grinding plug used to prepare and hold high concentration solution, such as volumetric flask, colorimetric tube, buret, etc., shall be poured out in time after use, discarded or stored in reagent bottle, and cleaned in time to prevent solute precipitation, block grinding plug and damage glass instrument Glass distillation utensil cleaning steps, cut off the power, turn off the tap water switch, remove the condensation pipe, but do not need to remove the plastic pipe Carefully add about 100ml of concentrated hydrochloric acid to the horizontal flask, dilute it with the water in the flask to form dilute hydrochloric acid If there is more scale, the amount of hydrochloric acid can be more After a few minutes, the water level is discharged by the water level device, and then the tap water is used to wash several times In order to remove the trace hydrochloric acid, the dead angle which is not easy to clean can be washed and cleaned by inserting the flask back and forth After the second distillation, the distilled water within 10 minutes shall be removed For the cleaning of the instrument, after distillation for a period of time, the scale will accumulate in the horizontal flask and on the surface of the quartz heating tube At this time, it needs to be cleaned The cleaning times mainly depend on the hardness of the tap water and the use time If the instrument is not cleaned for a long time, the distillation effect will be affected, and the heating tube will be damaged seriously, and the cleaning time will be extended
