Laboratory Water Purification

Laboratory water purification systems are essential for producing high-quality water required in a wide range of scientific, analytical, and industrial applications. From general-purpose pure water to ultra-high purity water used in sensitive procedures, reliable water purification is a critical part of maintaining accurate and reproducible results in the lab.


Our Laboratory Water Purification category covers a complete range of solutions to meet diverse water quality requirements:

  • Pure Water Systems
    Designed for routine laboratory tasks, these systems produce Type II or Type III water suitable for buffer preparation, media production, and general cleaning. They often integrate reverse osmosis, deionization, and activated carbon filtration to ensure consistent water quality.

  • Ultrapure Water Systems
    Engineered for applications that demand Type I water, including HPLC, molecular biology, and cell culture. These systems provide water with resistivity up to 18.2 MΩ·cm and low total organic carbon (TOC), supporting contamination-sensitive workflows.

  • Water Distillers
    Reliable and cost-effective solutions for producing distilled water in the lab. Available in single or double distillation configurations, they are ideal for applications that require stable water quality with minimal maintenance.

  • Reverse Osmosis Systems
    These systems serve as primary water treatment units, effectively removing ions, particles, bacteria, and organic compounds. Often used as a pre-treatment step for pure or ultrapure water production, reverse osmosis units ensure efficiency and extend the lifespan of downstream components.

  • Water Purification Accessories
    A full selection of essential components including replacement cartridges, UV lamps, pre-filters, storage tanks, and tubing. These accessories are designed to optimize performance, maintain compliance, and ensure the long-term reliability of your water purification systems.

  • Water Quality Monitoring Devices
    Accurate water quality control is critical for consistent laboratory results. We provide a range of conductivity meters, resistivity sensors, TOC monitors, and flow cells for real-time monitoring of purified water output, helping laboratories maintain high standards and meet regulatory requirements.


Whether you need purified water for basic laboratory operations or ultrapure water for high-precision analysis, our complete portfolio of laboratory water purification solutions ensures reliable performance and compliance with global laboratory standards.
