Distilled water is purified water produced through the distillation process, free from impurities, minerals, and microorganisms, suitable for various scenarios to achieve specific functions.

I. Medical and Laboratory Fields

• Laboratory Testing: Used as a solvent or diluent for cell culture, chemical analysis, and blood testing to ensure the accuracy of experimental results.
• Medical Equipment Cleaning: Cleaning endoscopes, surgical instruments, etc., to remove residues and reduce the risk of infection.
• Pharmaceutical Preparation: Used for preparing injections or diluting medications to ensure drug safety and stability.
• Wound Care: Its low osmotic pressure helps clean wounds and promotes the rupture of residual cells to reduce infection risk, but it must be used in conjunction with professional disinfectants.

II. Industrial and Electrical Applications

• Electrical Equipment Maintenance: Used as coolant for humidifiers or batteries to prevent scale formation and circuit short circuits.
• Precision Cleaning: Removing grease from circuit boards and engine parts, with residue levels below industry standards.

III. Daily Life Uses

• Skincare and Beauty: Short-term facial application can soothe sensitive skin and improve hydration, but moisturizing products should be used to avoid dryness.
• Household Cleaning: Used for mopping floors, washing dishes, or removing oil stains, with high efficiency.
• Short-Term Drinking: Promotes metabolism and detoxification, but long-term consumption may lead to mineral deficiencies; it should be balanced with other water sources.

IV. Other Fields

• Textile Printing and Dyeing: Used as a dyeing auxiliary to enhance permeability.
• Chemical and Battery Industries: Explored for use in lithium battery electrolytes to improve performance.

Precautions: Distilled water is not a universal solution; it cannot replace professional disinfectants in medical applications, and mineral intake should be balanced when drinking. Industrial and homemade distilled water differ in purity and should not be mixed.
