How to Select the Right Laboratory Water System

Choosing the optimal water purification solution depends on your facility scale, water quality requirements, daily consumption and compliance needs. Consider the following core factors:

1. Facility scale and water points: For facilities with 3+ laboratories or more than 5 water points, a central pure water system is more cost-effective for unified management. For single-laboratory use, a benchtop ultrapure system offers more flexibility.
2. Required water quality grade: For routine glassware washing and general chemistry, Grade III RO water is sufficient. For HPLC, ICP-MS, cell culture and molecular biology, Grade I ultrapure water with TOC and endotoxin control is required.
3. Daily water consumption: Match system production capacity to your peak daily water demand with appropriate redundancy. Central systems cover 200–2000 L/H, while benchtop systems cover 10–150 L/H.
4. Compliance requirements: For GLP, GMP or audited laboratories, select systems with data logging, audit trails and password protection such as the Q-STER series to support compliance verification.
5. Feed water conditions: For areas with poor or fluctuating tap water quality, the double-stage RO Q-STER-G or EDI-based Q-STER-E delivers more stable effluent quality.

Summary

QiQin’s full line of laboratory water purification systems covers all scenarios from small benchtop units to large-scale centralized water supply, with consistent compliance with global mainstream water quality standards.
