DI Water – Ultra-Pure Deionised Water for Industrial & Laboratory Use

DI Water—short for deionised water, sometimes called demineralised water—is an ultra-pure form of water that’s been stripped of almost all its mineral ions. That includes common cations like sodium, calcium, iron, and copper, as well as anions such as chloride and sulphate. Essentially, it’s water in its purest practical form. This level of cleanliness matters—especially in environments where even the tiniest trace of salts or minerals could affect a process, a test result, or a finished product.

All across Perth—and really, throughout much of Australia—DI Water plays a quiet but crucial role. You’ll find it in labs, pharmaceutical production lines, electronic manufacturing setups, and even in automotive servicing. It’s the behind-the-scenes player ensuring processes run clean and smooth. When consistency and cleanliness are non-negotiable, DI water’s the obvious choice.

What Is DI Water?

Deionised water is created using ion-exchange resins that essentially “grab” the electrically charged ions from the water and remove them. It’s a different process from distillation, which involves heating and condensing water vapor. Instead, this method uses a chemical exchange to eliminate both positive and negative ions. The result? Water with almost no electrical conductivity and an impressively low total dissolved solids (TDS) count.

People also refer to it as “demineralised water” or, in American spelling, “deionized water.” You’ll often see purity expressed in terms of resistivity (MΩ·cm) or conductivity (μS/cm). And depending on the application, the purity can be tailored to specific requirements—lab-grade, industrial-grade, and everything in between.

Common Applications of DI Water

Thanks to its minimal ionic content, DI Water is ideal for use in areas where standard tap or filtered water just isn’t clean enough. It’s commonly used in:

• Laboratories: Perfect for preparing chemical solutions, rinsing glassware, or simply as a reliable solvent base.
• Electronics and Semiconductor Manufacturing: Prevents mineral deposits from interfering with precision parts and delicate cleaning tasks.
• Pharmaceutical and Cosmetic Industries: Keeps formulations pure and ensures compliance with GMP standards.
• Automotive Industry: Used in batteries and cooling systems to help prevent corrosion and mineral scale build-up.
• Boiler Feedwater and Cooling Towers: Minimises scale, extends equipment life, and boosts operational efficiency.

Packaging, Safety & Documentation

• CAS Number: 7732-18-5
• Appearance: Clear, colourless, odourless liquid
• pH: Neutral (7.0), or adjusted as needed
• Conductivity: Typically less than 1.0 μS/cm (can be customised)

Storage & Handling: Always store in sealed, clean containers away from direct sunlight or contaminants. For lab use, we recommend sterile handling protocols to avoid reintroducing impurities. Also, keep away from reactive substances—it may be “just water,” but ultra-pure DI water can still cause unexpected reactions when exposed to certain materials.
