Quartz sub-boiling high purity water distiller installation: After the instrument is unpacked, the condensing tube is taken out, and after being disinfected, the water outlet of the distilled water on the grinding port of the horizontal flask (which should face the front) is inserted, so that the other end of the rubber tube at the nozzle of the water level device is placed on the upper water outlet of the condensing pipe. The short rubber tube in the previous section is placed in the water outlet of the water level, but it should be noted that the pipeline is unblocked and should not be higher than the horizontal line at the outlet to avoid affecting the water level in the distillation bottle. The rubber hose is now placed in the lower inlet of the condenser. And connected to the water source, the tap water is from the cooling pipe, the water level device to the horizontal flask, the water level is controlled by the water level device, the cooling water route is the tap method, enters the lower water inlet of the secondary cooling pipe, through the upper and lower The nozzle flows into the lower water inlet of the primary cooling pipe, and flows into the water level device from the upper water outlet. When the first distillation is performed, the power is turned on, and one distillation starts first, and the distilled water flows into the secondary distillation bottle until the water level reaches the desired height. (about 1 hour) plug in the secondary power plug, secondary distillation began to distill, the purity of the distilled water is further improved, the amount of water per hour is about 2000 ml - 2500 ml. Cleaning of quartz sub-boiling high-purity water distiller: After a period of distillation, the scale is suddenly placed in the horizontal flask and on the surface of the heating tube. At this time, cleaning must be carried out. The number of cleaning depends mainly on the hardness and time of use of the tap water. If the instrument is not cleaned for a long time, Affect the distillation effect, severely damage the heating tube, and the cleaning time should be extended. Cleaning steps: 1. Turn off the power and turn off the tap water. 2. Add 100 ml of concentrated hydrochloric acid to the horizontal flask, and release the hydrochloric acid with the water in the bottle. If the scale is taught, the polychloric acid can be put more, and after a few minutes, it is released by the water level device, and finally rinsed with tap water several times in order to remove trace hydrochloric acid. The flask can be shaken back and forth to rinse out the dead corners that are not suitable for cleaning. 3. When it is distilled again, the water distilled in 10 minutes is started, and it is discarded.
