What is cleaning agent?
Cleaning agent is a surface-active cleaning solution, a radioactive contamination decontamination agent. It can be used in the laboratory, medical and special industrial sectors. It is biodegradable, phosphate-free, highly bactericidal, fully rinseable, and non-flammable, and is available as a concentrated liquid that can be diluted with water.
Cleaning agents in laboratory are alkaline emulsion concentrate (pH 13+) synthesized from amphoteric surface activators, stabilizers, alkalis, non-phosphate detergents, and multivalent chelating agents.
Laboratory detergent is used for the complete cleaning or pollution purification of glass products, ceramic products, plastic products (non-polycarbonate), rubber products, stainless steel products, and ferrous metal products, safe and effective. As an alkaline substance, laboratory detergent is not suitable for non-ferrous metal products, especially aluminum and zinc products, nor for polycarbonate products. Not suitable for home use.
Types of cleaning agents
Laboratory cleaning agents are a large category with a wide variety, including inorganic cleaning and organic cleaning two categories. Organic cleaning is a
cleaning agent made of compounds containing carbon. Inorganic cleaning is a cleaning agent made of compounds that do not contain carbon, so they belong to inorganic substances.
There are also many ways to classify
cleaning agents, and they vary from country to country. Cleaning agents are usually divided into three categories: aqueous, semi-aqueous, and non-aqueous.
Laboratory cleaning agent is only a very important part of the cleaning process, other factors are equally important, such as time, temperature, mechanical force, and water quality. Several factors interact with each other and also compensate for each other, in the cleaning process other factors or cleaning machine hardware and software defects in themselves, it is difficult to make up. A cleaning agent is not able to deal with all pollutants, different pollutants need to match different components of the cleaning agent.
Different cleaning agents
a. 5% concentration oxalic acid solution. It can remove the potassium permanganate residue in glassware.
b. 5%-10% concentration of trisodium phosphate (Na3PO4-12H2O) solution. It can remove oil contaminants.
c. 30% concentrated nitric acid solution. It is usually used to clean the micro-dropper and carbon dioxide meter.
d. 5%-10% concentration of disodium ethylenediaminetetraacetate (EDTA-Na2) solution. It is used to clean the white precipitates on the inside of glassware, which needs to be heated and boiled before use.
e. Industrial concentrated hydrochloric acid. It removes certain inorganic salt precipitates as well as scale. It is generally stored in cylinders of chlorine gas in hydrogen combustion to generate hydrogen chloride and then pass into the water to make.
f. Organic solvents. According to the chemical principle of similar solubility, organic solvents can also be used for cleaning, such as ethanol can clean grease and fat-soluble stains, xylene can clean paint, and so on.
g. Urea washing solution, which is a good solvent for proteins. It is mostly used to clean residual proteins in glassware.
h. Chromic acid cleaning solution. It can effectively remove oil, handprints, and other dirt. Pay attention to safety and wear protective gear when preparing. Configuration method: add 100ml of concentrated industrial sulfuric acid in a beaker, slowly add 5g of potassium dichromate powder while heating, and constantly stirring, to dissolve all the potassium dichromate powder, and then cool to produce a chromic acid cleaning solution.
i. Water. It is the most used natural laboratory detergent. However, it can only wash away dirt that can be dissolved in water. Dirt that cannot be dissolved in water. Utensils need to be treated with other methods before washing with water. After washing with clean water, it needs to be washed with distilled water again.
j. Using the chemical reaction between the washing solution and the dirt, the dirt is removed. Therefore, it needs to soak for a certain period of time to fully act. It is mostly used for glassware that is inconvenient to be washed by brush, such as burette, pipette, volumetric flask, distiller, and other special-shaped glassware, and also used to wash cups and utensils which are not been used for a long time and the scale which cannot be brushed by brush.
The above cleaning agents can be configured in the laboratory to obtain, but the function is relatively single, the preparation time-consuming and labor-intensive, which invariably reduces the efficiency of the experimental staff. It is recommended to purchase a special cleaning agent, which not only saves time and effort but is also safer and more reliable when used.
Cleaning agents used in the food industry
In the 20th century, various laboratories sprang up and research was carried out extensively. With the development of science and technology, it is difficult to measure the control of laboratory microorganisms. Laboratories have high requirements for cleanliness. The number of microorganisms in the air must be strictly controlled to prevent the contamination of target strains and vessels by stray bacteria. After the experiment, samples should be destroyed and the space and equipment should be disinfected to prevent microorganisms from contaminating the external environment.
Currently, ozone or formaldehyde fumigation combined with sporicides is widely used for laboratory space cleaning and disinfection. However, ozone has limited sterilization ability and formaldehyde fumigation is harmful to the human body. Disinfection requires vacancy for 2-3 days before personnel is allowed to enter the clean area, which not only greatly reduces the productivity of the laboratory, but also is not easy to verify.
Cleaning and disinfection of laboratories should achieve disinfection and sterilization without endangering personnel and equipment. Therefore, it is generally considered that food-grade cleaning agents with good cleaning and disinfection effects should be used. In general, the substances used in experiments are toxic and often produce a variety of unpleasant, corrosive, toxic, or explosive gases. If these harmful gases are not discharged outdoors in a timely manner, they will cause indoor air pollution, affecting the health and safety of laboratory personnel and the accuracy and service life of instruments and equipment. Clean rooms and sterile areas involving laboratory space contamination using food-grade cleaning agents. The purpose is to eliminate various pathogenic microorganisms that endanger human or animal life, to protect workers, collaborators, and laboratory support personnel from infection, and to protect products and the environment from contamination. Food-grade detergent is colorless, odorless, non-toxic, and residue-free. It is the world's most advanced microbial disinfectant for laboratory environments. Due to its unique principle of action, it can kill various types of microorganisms. IFS International Food Standard certification, EU EMAS testing certification, ISO9001, and ISO14001 environmental management system certification, etc. It is a highly efficient, broad-spectrum food-grade disinfectant. It has the characteristics of complete sterilization, no microbial resistance, no toxic residue, and no repeated contamination. Food-grade cleaning agents can clean the internal environment of laboratories, such as floors, object surfaces, walls, etc. Laboratory equipment, such as glass equipment, plastic, rubber, non-woven products, valuable instruments, paper, etc.
Laboratories have different opinions on sanitary conditions and disinfection measures, and there are a variety of problems. Both have commonalities and their own characteristics. A series of detailed treatments should be carried out according to the specific conditions of the respective laboratories, but the issue of laboratory disinfection is still very critical and should not be ignored. At the same time, a thorough approach should be taken. If mishandled, it will lead to the spread of disease.
Use of cleaning agent
The cleaning agent is generally a concentrated liquid. It needs to be diluted with water for use (recommended dilution concentration is 2~5%). Severe stains can be adjusted to a higher concentration.
a. When using, soak the utensils in the soaking solution for 2~24 hours, the soaking time depends on the stubborn nature and degree of stains.
b. Heating soaking solution (40~50°C) or using ultrasonic cleaning can greatly shorten the cleaning time.
c. It is recommended that the soaked utensils be rinsed repeatedly as soon as possible using running tap water for more than 3 times, and then rinsed with deionized water or distilled water more than 3 times to ensure complete removal of stains and cleaning agents.
d. The immersion solution can be used repeatedly and replenished. Soaking solution is too dirty, or the PH value is low to below 8, can be considered a failure, need to add the appropriate amount of organic acid to neutralize and then discharge as appropriate.
e. Please use covered high-density polyethylene plastic or stainless-steel containers for immersion.
f. After removing the utensils from the soaking solution, rinse them thoroughly immediately and do not leave them for too long before washing them.
Note
a. Laboratory cleaning agent is alkaline, suitable for laboratory glass, ceramics, stainless steel, plastic products (excluding polycarbonate), iron products, and rubber. Not suitable for cleaning aluminum, zinc, non-ferrous metals, latex, and polycarbonate products. For materials not mentioned, please do a material compatibility test beforehand.
b. When using this product, please wear chemical safety glasses and rubber gloves.
