FAQs
Why should I choose deionized water for lab use?
This ultra-pure reagent water minimizes ionic interference, making it ideal for analytical chemistry, reagent preparation, and rinsing sensitive glassware.
Does DI water at 18 MΩ lose purity over time?
Yes. While freshly produced deionized water is extremely pure, once a container is opened, it can absorb carbon dioxide and trace ions from the air. Always keep Water Deionized D.I. 18 MΩ tightly sealed.
What’s the proper way to store A.C.S. Type I reagent water?
Store in a clean, cool place, away from direct light. Use compatible containers such as HDPE or glass to preserve the purity of DI water.
Can deionized water 18 MΩ corrode metals or lab equipment?
Ultra-pure DI water is aggressive because it lacks ions and may leach ions from metal surfaces. For this reason, use Water Deionized D.I. 18 MΩ with non-reactive materials designed for high-purity water.
Is Water Deionized D.I. 18 MΩ safe to handle?
Yes. Unlike acids or solvents, reagent-grade DI water is non-toxic and non-flammable. Normal lab hygiene practices, clean handling and sealed storage, are sufficient.
Can I use deionized reagent water for cleaning labware?
Absolutely. Water Deionized D.I. 18 MΩ leaves no mineral residue, making it excellent for final rinses of glassware, pipettes, and other sensitive instruments.
