    1. Pre-operation Preparation

    
    
    Before starting any operation, conduct a comprehensive visual inspection on the product. Check whether the outer package and inner container are intact and well sealed. Observe the physical state of the powder to confirm it is uniform white crystalline powder, free from discoloration, caking, deliquescence and peculiar odor. Do not use the material if any abnormal phenomenon is found.
    
    
    Prepare corresponding tools and containers in advance, including precision weighing instruments, dry beakers, measuring cylinders, stirrers and sealed storage vessels. All utensils must be fully cleaned, dried and sterilized according to experimental or production standards to eliminate residual impurities and moisture. Select suitable dissolving medium according to actual application demands; purified water or deionized water is the preferred solvent for most conventional formulas and biochemical experiments.
    
    
    Operators shall put on disposable dust-proof gloves, protective goggles and dust masks to prevent the inhalation of fine powder, direct contact with skin, mucous membrane and eyes. It is forbidden to eat, drink or move around casually in the operating area during the whole process.
    
    

    2. Weighing and Sampling

    
    
    Place the sealed container stably on the operating platform, open the container gently to prevent powder from splashing. Use professional weighing tools to take materials in required quantity slowly and accurately. Try to shorten the exposure time of the powder in the air, so as to reduce the risk of oxidation and moisture absorption caused by long-term contact with air.
    
    
    After completing sampling and weighing, immediately tighten the container cap and seal the package completely. Follow the storage rules and put the remaining product back into the specified low-temperature storage area in a timely manner. Record the sampling time and residual quantity for daily inventory management.
    
    

    3. Dissolution and Liquid Preparation

    
    
    Transfer the weighed powder into the pre-prepared clean container, add the selected solvent slowly at a steady rate. The recommended temperature of solvent is controlled at room temperature between 20℃ and 25℃, which can effectively maintain the original chemical properties of the material.
    
    
    After adding solvent, let the mixture stand for a short while, then stir gently and continuously with a stirrer until the solid powder is fully dissolved and forms a homogeneous clear solution. Do not stir violently or shake the container fiercely, to avoid generating a large number of bubbles which may affect the subsequent use and detection.
    
    
    If it is necessary to prepare solutions with different concentration gradients for experimental research or formula testing, dilute the mother liquid step by step in accordance with technical schemes. Calculate the proportion strictly and operate step by step to ensure the concentration of the finished solution meets the technical requirements.
    
    

    4. Application in Different Scenarios

    
    
    • Laboratory Biochemical Research: Use the prepared solution to carry out redox related experiments, enzyme activity tests, component analysis and other academic researches. Follow the established experimental protocols and technical specifications for all test steps to guarantee the accuracy and repeatability of experimental data.
    • Cosmetic & Daily Chemical Formulation: Add the fully dissolved solution into the cosmetic base materials in proportion during the batching process, and conduct uniform blending as required by the formula. It serves as a functional auxiliary raw material for system stabilization, not for direct skin application.
    • Industrial Chemical Synthesis: Use the prepared liquid as reaction raw material or intermediate, and put it into the production system according to industrial process flow for synthetic reaction and continuous production.
    
    

    5. Temporary Storage of Prepared Solution

    
    
    The stability of the aqueous solution is much lower than that of solid powder. If the prepared solution cannot be used up immediately, seal the container tightly and store it in a cool and dark environment at 2℃~8℃. It is suggested to use all liquid within 24 hours.
    
    
    It is strictly prohibited to store the solution at room temperature for a long time or freeze it at low temperature. Extreme temperature will destroy the molecular structure of the active substance and lead to performance degradation. Do not reuse the remaining solution after long-term placement.
    
    

    6. Post-operation Treatment & Waste Disposal

    
    
    After all work is finished, clean all used containers, tools and operating sites thoroughly to remove residual powder and liquid. Classify and treat waste liquid and waste residues in compliance with laboratory and industrial waste management regulations. Do not pour waste randomly to prevent environmental pollution.
    
    

    Important Notes

    
    
    This product is only for laboratory research, industrial production and raw material formulation use. It is forbidden for human oral intake, injection, medical treatment and direct body care use. Any operation beyond the applicable scope is not allowed. Users shall take full responsibility for safety risks arising from improper operation.

• Storage Instructions

  
  
  Reduced Glutathione is a thiol-containing tripeptide compound with special chemical properties. Its physical and chemical state is susceptible to high temperature, intense light, ambient moisture and prolonged exposure to air. Strict standardized storage management must be implemented throughout the whole cycle to maintain its original purity, activity and stable physical form.
  
  

  1. Storage Environment & Basic Requirements

  
  
  The overall storage area shall be kept clean, tidy, dry and well ventilated. The indoor relative humidity is controlled within 40% to 60% to prevent the powder from absorbing moisture and deliquescing. Keep away from direct strong sunlight, thermal radiation, heating equipment and heat sources. Meanwhile, isolate this product from strong oxidants, acidic and alkaline chemicals, volatile reagents and corrosive substances to avoid undesirable chemical reactions.
  
  
  This material shall be stored separately. Do not place together with food, drinks, daily necessities, toxic or hazardous chemicals. The storage location should be away from living areas and public passages, and keep out of reach of children and unrelated personnel.
  
  

  2. Storage for Unopened Products

  
  
  All original sealed packages should be placed in a constant temperature refrigerated environment at 2℃ ~ 8℃. Stack products neatly and reasonably, avoid excessive extrusion and heavy pressure on the packaging. Do not place the goods close to the refrigerator cooling outlet to prevent local supercooling affecting the material properties.
  
  
  Under the above specified storage conditions, the shelf life of unopened products is 24 months. Please refer to the production date and expiry date marked on the package for use arrangement. Short-term placement at room temperature (15℃ ~ 25℃) is only permitted during cargo handling, transit and temperature adaptation, and the duration shall be minimized. Long-term room temperature storage is prohibited.
  
  

  3. Storage for Opened Products

  
  
  Once the original airtight seal is broken, the internal powder will be in contact with air and moisture, which will greatly increase the risk of oxidation, discoloration and agglomeration. After each sampling and use, tighten the container cap immediately and seal the mouth tightly. Sealing film or professional sealing equipment can be used for secondary reinforcement to isolate external air and humidity thoroughly.
  
  
  Put the sealed container back to the 2℃ ~ 8℃ refrigerated area in a timely manner. It is recommended to use up all remaining materials within 7 days after opening. Do not leave opened containers in the operating room or room temperature environment for a long time. Record the opening date for subsequent use and quality tracking.
  
  

  4. Storage of Prepared Solution

  
  
  The aqueous solution prepared from this powder has far lower stability than solid powder. It is forbidden to store the solution at room temperature for a long time or freeze it at below 0℃. Low temperature freezing will destroy the molecular structure of active ingredients and cause irreversible performance loss.
  
  
  If the prepared solution cannot be used immediately, seal the container completely and store it at 2℃ ~ 8℃ away from light. Please finish all usage within 24 hours. Discard the residual solution that has been stored for too long, and do not reuse it.
  
  

  5. Transportation & Handling Notes

  
  
  During transportation, keep the packages upright and stable. Avoid violent shaking, rolling, collision and severe extrusion. Prevent packaging damage and powder leakage. Do not expose the goods to sunlight or high temperature environment for a long time during transit. For long-distance delivery, cold chain transportation is recommended to guarantee product quality.
  
  
  When moving and carrying, handle gently and follow the stacking standard. Do not invert the packages randomly.
  
  

  6. Regular Inspection & Abnormal Handling

  
  
  Carry out regular visual inspection for all stored products on a daily basis. Focus on checking the tightness of package sealing, the appearance of powder and whether there is moisture seepage.
  
  
  If abnormal conditions such as powder discoloration, caking, peculiar smell or package damage are found, isolate the problematic goods immediately, mark them clearly and stop using. Conduct classified disposal in accordance with relevant material management regulations.
