Merck Millipore Direct-Q®3UV Ultrapure Water Purification System Model 5565

The Merck Millipore Direct-Q®3UV ultrapure water purification system (Model 5565) is designed for producing ultrapure water with a maximum flow rate of 0.5 L/min and resistivity of 18.2 MΩ·cm, ensuring high purity necessary for sensitive biotechnology and molecular diagnostics applications. This system utilizes UV purification technology combined with advanced filtration to deliver water quality suitable for cell culture, bioprocessing, and molecular biology workflows.

Key technical features:

• Maximum flow rate: 0.5 L/min, supporting continuous laboratory demands
• Water sources: Compatible with tap water and well water; ion-exchange and other purified waters are not acceptable inputs
• Water quality: Produces ultrapure water with resistivity of 18.2 MΩ·cm, critical for molecular diagnostics and bioprocessing
• Tank capacity: 4.5 liters, providing sufficient onsite supply
• Electrical: Operates on wide-range power supply (100–230 V, 50/60 Hz, 0.7 A) for versatile laboratory environments
• Physical dimensions: Compact footprint measuring 29×54×42 cm and weighing 7.5 kg for benchtop use
• Additional system components: Equipped with a vacuum reducing valve and leak detection system for enhanced operational safety and reliability

This ultrapure water system is widely used in biotechnology sectors, particularly for gene editing, molecular cloning workflows, and bioprocessing pipelines requiring contaminant-free water. The system’s precise water quality control and UV disinfection capabilities make it a critical instrument in clinical diagnostics, synthetic biology research, and biomanufacturing. Sold as a used unit, performance should be verified prior to deployment.
