Pure water is widely used and indispensable in laboratory work, mainly reflected in the following aspects:

1. Experimental Operation

Sample treatment: Pure water serves as a basic solvent and diluent for various experimental samples, effectively removing interfering substances and guaranteeing the authenticity of experimental data.

Reagent preparation: All kinds of chemical reagents, culture media and standard solutions are prepared with pure water to keep the chemical properties of reagents stable.

Experimental analysis: Conventional detection and analytical tests such as titration, spectrophotometry and chromatography rely on qualified pure water to ensure accurate and repeatable test results.

2. Laboratory Equipment Cleaning and Maintenance

Routine cleaning: Glassware, reaction vessels and experimental devices are cleaned with pure water to avoid residual impurities affecting subsequent experiments. 

Instrument maintenance: Precision analytical instruments need regular flushing and maintenance with pure water, which can extend the service life and maintain stable operating performance.

Pipeline protection: Water supply pipelines of laboratory equipment are rinsed with pure water to prevent scaling and corrosion.

3. Laboratory Environment Management

Humidity control: In biochemical, microbiological and physical laboratories, pure water is used in humidification systems to maintain a suitable and constant environmental humidity.

Air purification: Part of the laboratory air treatment systems adopt pure water for humidification and filtration, creating a clean experimental environment.

4. Sample Storage and Preservation

Short-term preservation: Some liquid samples and biological specimens are diluted and stored with pure water to slow down sample deterioration. 

Container soaking: Storage containers are soaked and cleaned with pure water in advance to prevent secondary contamination of stored samples.

5. Scientific Research and Experiment Development

Basic research: Pure water is a fundamental condition for all basic experiments and exploratory research in laboratories.

Experiment optimization: As experimental standards become increasingly rigorous, higher-grade pure water is adopted continuously to meet the demands of cutting-edge scientific research.

6. Industry Specifications and Compliance

Laboratory standards: National and industrial laboratory management standards put forward clear requirements for water quality. Standard pure water is a must for standardized laboratory operation.

Quality certification: Laboratories applying for industry qualification and certification need to prove that the water used complies with relevant international and domestic water quality standards.

7. Safety and Protection

Experimental safety: High-purity water reduces chemical reactions caused by impurities, lowering the risk of unexpected experimental accidents.

Personal protection: Using pure water for operation and cleaning reduces the contact between researchers and harmful pollutants, protecting personal health.

8. Overall Operational Competitiveness

Data credibility: Stable high-quality pure water ensures reliable experimental results, improving the overall technical capability of the laboratory.

Laboratory reputation: Strict water quality control reflects standardized laboratory management and helps build a professional and trustworthy industry image.

In general, the application of pure water runs through all links of laboratory work. It is closely related to experimental accuracy, equipment safety, compliance management and personnel protection.

Therefore, all laboratories must strictly control water quality and standardize the use of pure water, so as to provide a solid guarantee for daily experiments and scientific research.
