I.Overview
Deionized water (DI water) equipment is crucial as a base solvent in the preparation of plant culture media, and its purity directly affects plant cell growth rates, gene expression stability, and experimental reproducibility. The core value of DI water in plant culture: the cornerstone of gene research, a growth accelerator, a pollution firewall, and a prerequisite for standardization.
II.Customized processes tailored to plant cultivation
Raw Water→Ultrafiltration (UF)→RO (Reverse Osmosis)→CEDI (Continuous Electrodeionization)→UV Sterilization→ Terminal Ultrafiltration→Medium Preparation

V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
