Bespoke 500 liters/h ultrapure water filtration system for blank controls for precision instruments
I.Overview
The application of ultra-pure water in blank controls is of critical importance, particularly in precision analytical experiments that are highly sensitive to contaminants. It serves as a “zero background” or “background” reference, forming the cornerstone and gold standard of blank control experiments.
By providing a reference with a background level close to zero, it helps experimenters: confirm (whether the “water” used in the experiment is pure and free of interference), diagnose (whether contamination has been introduced by experimental containers, consumables, operational processes, or the instrument itself), calibrate (instrument baseline, assess system noise), and ensure (the accuracy and reliability of final sample measurement results, particularly for trace, ultra-trace analysis, and highly sensitive biological experiments).
II.Process
Raw water → Multi-stage filtration → Precision filtration → RO → Ion exchange/EDI → UV sterilization → Ultrafiltration/Microfiltration → Outlet water

V.Key points for using ultrapure water
Use immediately after dispensing
Avoid storage
Dedicated water outlet
Regular monitoring and maintenance
Select the appropriate water quality level
VI.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 )
