1. Frosted Bottle Mouth: Manually processed through one-to-one fine frosting, featuring a delicate and uniform grinding surface without any blank areas, and the edge is chamfered to prevent hand pricking.
2. Thick and Stable Base: The bottom is stable and broad, ensuring a stable placement without any swaying.
3. Light Shielding Capacity: The brown design can effectively block ultraviolet and visible light, safeguarding light-sensitive reagents from photodecomposition.

Working Environment Conditions:
1. Temperature and Humidity: The temperature should range from 16°C to 26°C, and the humidity should be within 30% to 65%.
2. Illumination: Brown bottles need to be shielded from light to avoid direct exposure to ultraviolet rays and intense light.
3. Ventilation: Adequate ventilation is essential, particularly when volatile or corrosive liquids are stored.
4. Cleanliness: The laboratory should be maintained clean to prevent contamination by dust and microorganisms.
5. Shock Resistance and Safety: The bottles should be placed stably to avoid collisions and ensure tight sealing.

Notes:
1. Seal Inspection: Prior to utilization, examine whether the bottle cap is well-sealed to prevent liquid leakage.
2. Cleaning and Disinfection: Thorough cleaning is necessary before and after use. Disinfection should be carried out when necessary to avoid cross-contamination.
3. Chemical Compatibility: Ensure that the material of the water storage bottle is compatible with the liquid it holds to avoid chemical reactions.
4. Flow Control: Pay attention to the flow during use to prevent liquid splashing or waste.
5. Clear Labeling: Clearly mark the bottle with information such as the name of the contents, concentration, and date.
6. Safe Storage: Place the bottles in a stable and well-ventilated location, away from heat sources, fire sources, and intense light.
7. Specialized Management: When it comes to hazardous chemicals, they should be managed and utilized by specialized personnel.
