Ultra Pure Water Machine for Laboratory

Ensuring Ultra‑Pure Water for Critical Research with Laboratory‑Grade Pure Water Systems

Many analytical techniques—high‑performance liquid chromatography (HPLC), mass spectrometry, and molecular biology assays—demand water of the highest purity. The Ultra Pure Water Machine for Laboratory from Changsha Friend Experimental Analysis Instrument Co., Ltd. provides a comprehensive, multi‑stage purification process to deliver resistivity > 18 MΩ·cm and ultralow organic, ionic, and particulate content.

The Role of Pure Water in Modern Labs

Impurities in water can cause background noise, column fouling, and compromised assay sensitivity. Consistent access to ultrapure water enhances reproducibility and extends instrument service life.

Multi‑Stage Purification Process

1. Pre‑filtration: Removes particulates larger than 5 µm.

2. Activated carbon adsorption: Eliminates chlorine, organics, and residual disinfectants.

3. Reverse osmosis (RO): Rejects > 95% of dissolved salts and macromolecules.

4. Ion‑exchange polishing: Achieves resistivity > 18 MΩ·cm.

5. UV photo‑oxidation: Degrades trace organics and bacteria.

6. Final sub‑micron filtration: Ensures particle‑free output.

System Features

• Continuous production: Provides on‑demand ultrapure water at flow rates up to several liters per minute.

• Touchscreen controls and diagnostics: Enable real‑time monitoring of resistivity, TOC (total organic carbon), and flow.

• Compact footprint: Fits in crowded laboratory environments.

• Automated sanitization cycles: Preserve microbial control without manual intervention.

Use Cases

• Analytical chemistry: HPLC, GC–MS, and titration.

• Biotechnology: Cell culture media preparation, PCR, and ELISA.

• Semiconductor manufacturing: Wafer rinsing and chemical preparation.

• Environmental testing: Trace metal and pesticide analysis.

Maintenance Recommendations

Regular cartridge replacements, UV lamp checks, and membrane cleanings ensure sustained performance. The system’s self‑diagnostic alerts simplify upkeep and minimize downtime.
