Ultrapure Su Nedir? | What is Ultrapure Water?

Short answer: Ultrapure water (UPW) is water purified to extremely low conductivity (<0.055 µS/cm), low TOC and controlled bacteria/endotoxins for pharmaceutical, semiconductor and laboratory use.

What is Ultrapure Water?

UPW exceeds demineralized quality. Production typically uses pre-treatment, double-pass RO, EDI, UV oxidation, microfiltration and recirculating loops with 18 MΩ·cm resistivity at point of use.

Quality Parameters

• Resistivity: 18.2 MΩ·cm at 25°C
• TOC: <500 ppb (stricter for pharma)
• Bacteria/endotoxin per pharmacopoeia

FAQ

UPW vs demineralized water?

UPW has tighter limits on TOC, particles and microbes; demin water targets conductivity only.

What is WFI?

Water for Injection — pharma grade produced by distillation or qualified RO+UF per USP/EU.
