Laboratory water purification

Core value of water quality

The physical and chemical purity of experimental water directly affects the accuracy of the reaction:

Solubility: >99% inorganic salts are soluble (25℃ conductivity ≤0.1μS/cm)

Biocompatibility: experiments such as nucleic acid/cell culture require TOC <5ppb

Pollution control technology route

Use three-level barriers to eliminate five types of pollutants:

Ion exchange system

Deep desalination of strong acid/strong base resin (resistivity ≥18.2MΩ·cm)

Acid-base regeneration process reduces operating costs by 40%

Reverse osmosis unit

Composite membrane stack interception rate >99.5% (operating pressure ≥60bar)

PP melt-blown filter pre-protection (pore size 1μm)

Ultraviolet disinfection module

254nm UV lamp kill rate＞6log (dose≥40mJ/cm²)

Quartz sleeve ensures UV transmittance＞95%

System integration solution

Terminal refining unit: ultrafiltration membrane (0.22μm) blocks pyrogens

Intelligent monitoring system:

Online resistor monitors water quality in real time

TOC analyzer automatically samples every 30 minutes

Modular design: separate architecture of host and water storage tank

Application benefit verification

Analysis accuracy guarantee:

HPLC baseline noise reduced by 50%

Cell culture survival rate increased to 98%

Comprehensive cost optimization:

70% energy saving compared to traditional distillation

Consumables replacement cycle extended to 12 months

Water quality compliance:

Meets ASTM Type I standard

Microbial index＜1CFU/mL
