In modern laboratories, water quality is one of the most critical factors influencing experimental accuracy, reproducibility, and compliance with international standards. In Malaysia’s growing scientific, pharmaceutical, academic, and industrial research sectors, choosing the right lab water purification system isn’t just a preference – it’s a necessity. Two primary choices dominate the market: Centralised systems and Point-of-Use (POU) systems. Each has its strengths and limitations, and the best fit depends on your lab’s size, budget, workflow, and water quality demands.
Understanding Purified Water Grades in Laboratory Use
Before comparing system types, it’s important to understand water quality classifications typically used in labs:
- Type I (Ultrapure): Highest quality water used for molecular biology, cell culture, HPLC, IC, and sensitive assays.
- Type II: General laboratory applications, media prep, routine analysis.
- Type III (Purified): Initial wash water, glassware cleaning, routine lab tasks.
- RO (Reverse Osmosis) water: Often a pre-treatment stage for higher purity needs.
