Why Water Purity Matters in Laboratories?

Impurities such as ions, particulates, organic compounds, and bacteria can interfere with experiments, causing inaccurate results and damaging sensitive instruments. Using the correct lab water purification system ensures:

• Consistent and reproducible results
• Protection of sensitive analytical instruments
• Compliance with laboratory standards (GLP, GMP, ISO)

Types of Pure Water for Laboratories

Laboratory water is typically classified based on its purity level according to ASTM, CLSI, and ISO standards. The three main types are Type I, Type II, and Type III water.

Type I – Ultrapure Water

What it is:
Type I water is the highest grade of laboratory water, also referred to as ultrapure water. It is free from virtually all impurities, including ions, organics, particulates, and bacteria.

How it is produced:
Ultrapure water purification for clinical labs or research labs
Uses reverse osmosis, deionization, UV oxidation, and ultrafiltration

Applications:
HPLC, GC, and LC-MS
Cell culture and tissue diagnostics
Molecular biology and genomics
Critical pharmaceutical formulations

Recommended System:
Ultrapure water systems like those provided by Lablink are designed specifically for analytical and life sciences laboratories.

Type II – Pure Water

What it is:
Type II water is high-purity water suitable for general laboratory applications where ultrapure water is not required.

How it is produced:
Deionization and reverse osmosis systems

Applications:
General reagent preparation
Buffer and media preparation
Clinical diagnostics and microbiology labs

Recommended System:
A Type II water purification system for research labs ensures consistent water quality for routine experiments.

Type III – Primary Grade Water

What it is:
Type III water, also known as primary grade or feedwater, is less pure but ideal as pre-treated water for laboratory instruments.

How it is produced:
Reverse osmosis and basic filtration

Applications:
Glassware washing with automated acid cleaners
Feedwater for ultrapure water systems
Steam generation for autoclaves and humidifiers

Recommended System:
Lab water systems for research and industrial labs often combine Type III feedwater with Type I/II systems for cost-efficient operation.

Choosing the Right Water System for Your Lab

Selecting the right laboratory water purification system is crucial for maintaining accuracy and reliability in experiments. The first factor to consider is your application requirements—whether you need ultrapure water for analytical techniques like HPLC and GC-MS, or general pure water for reagent preparation and glassware washing. The required purity level also plays an important role, as different applications demand different water grades such as Type I, Type II, or Type III. Additionally, the daily water consumption volume should be assessed to choose a system that can meet your laboratory’s usage without frequent downtime. Finally, evaluate the system maintenance requirements and long-term operating costs, as investing in a cost-efficient and low-maintenance system will ensure consistent performance while reducing operational expenses.
