What is acid cleaner?
Acid cleaner is mainly heated by multi-functional graphite electric heating plate to produce high-purity acid vapor on the vessels under the effect of repeated convection and condensation shower. It can thoroughly and safely clean various microwave digestion tanks used for trace analysis, various digestion tanks for conventional pressure digestion, glass such as test tubes, beakers, volumetric flasks, etc., quartz material experimental vessels, and trace cleaning of atomization chambers and flame tubes used for ICP. The general cleaning time is about 2-4 hours. Suitable for hydrofluoric acid, hydrochloric acid, nitric acid, sulfuric acid and water, and other reagents, is an automatic, airtight, acid steam cleaning instrument.
Application of acid cleaner
Acid cleaning system with cleaning, pure water rinsing, and drying in one, widely used in laboratory experimental vessel cleaning, can safely clean a variety of glass, quartz, PFA, PTFE, TFM, and other vessels in trace analysis and ICP/MS accessories of inorganic element residues, effectively reduce the ion background, to meet the needs of trace detection.
In addition, the acid cleaner has been widely used in food, agricultural products, grain and oil, the environment, and other fields, to help experimenters solve the difficult metal ion cleaning problems.
Acid cleaner working principle
The working principle of acid cleaner is to use the hot steam of sub boiling HF, HCL, HNO3, high purity water, alkali, and other common laboratory acids, bases, and other common solvents to clean reaction tubes, test tubes, dissolution tubes, beakers, crucibles, volumetric flasks, and other common laboratory utensils.
The whole cleaning process is heated through the heating plate to produce high-purity acid and alkali vapor on the repeated convection and condensation of the vessels under the effect of washing, the cleaner using air cooling and additional cooling water, can achieve economic overnight work, compared with conventional cleaning or acid bubble method, steam cleaning method of cleaning effect, cleaner.
Advantages of using acid cleaner
The use of acid cleaners has the following advantages:

Acid cleaner and glassware washer machine
Glassware washer machine definition
Glassware washer machine is composed of stainless steel water pump, high-pressure nozzle, electrical box, etc. It is suitable for glass bottles, plastic bottles, etc. Brush-type cleaning and water flushing type cleaning alone or with the use of special equipment for cleaning.
The bottle washing machine adopts high-pressure backwash spraying and washing so that the debris on the bottle wall can be detached and fall into the water tank in time.
Difference between acid cleaner and glassware washer machine
The difference between the acid cleaner and the glassware cleaner machine is very obvious in the inorganic experiments.
Ordinary glassware cleaner because the inside is made of stainless steel, so in the cleaning process, there must be part of the precipitation or dissolution, can not meet the inorganic experiments for the ultra-high requirements of the instrument.
Therefore, this requirement can only be met by the acid cleaning machine, because the entire inner cavity of the acid counter-current cleaning machine made of PTFE, can meet the high requirements of inorganic experiments.
How to use acid cleaner?
Standardized, automated acid steam cleaning machine must be the future laboratory trend. Acid steam cleaning machine washing quality can be guaranteed, the washing process is safe and reliable, washing records can be traced, the entire cleaning process from acid steam to dry without too much manual participation, 1-hour acid steam cleaning effect is equivalent to the acid tank soaked overnight. The cleaned utensils can reach a PPT level or even a non-detectable level.
Therefore, the following is the process of using the acid washer.
1. The first step, injected sub-boiling acid steam cleaning, ultrapure acid steam through the tube to clean the inner wall of the vessel, the vessel is slowly filled with acid gas, acid gas slowly condensation flow down, take away the metal ion residue.
2. In the second step, ultra-pure water injection rinsing, not less than 6L of ultra-pure water is automatically sprayed into the inner cavity of the equipment and the interior of the vessel, rinsing off the acid residue on the inner and outer walls of the vessel.
3. In the third step, hot air drying, the pipeline compressed fan blows the hot air filtered by HEPA into the interior of the vessel for efficient drying.
How to maintain acid cleaner?
For the acid cleaner to work efficiently for a long time, it is essential to do a good job of daily maintenance,
The following is the maintenance method for acid cleaner system.
1. Temperature sensor, PH meter, flowmeter, fan, etc. do a regular check once a quarter to see if they can work normally and if there are problems to be repaired in time.
2. We should always pay attention to observe whether the action of each part is synchronized, whether there is any abnormal sound, whether the fasteners in various places are loose, whether the nozzles and filters are blocked and cleaned, and once abnormal conditions are found, they should be dealt with in time.
3. Before each use, check whether there is sufficient reagent liquid in the alkali bottle and acid bottle, and if not, add it to the corresponding position in time.
4. Every six months, we need to check the color change of the acid gas filter adsorption column, if the color is lighter, we need to replace the filter adsorption column.
