Astacus² Ultra Pure Water System

The Astacus² Ultra Pure Water System is a premium-grade Type I water purification system designed by membraPure GmbH for demanding laboratory and analytical applications. It produces ultrapure water with a resistivity of 18.2 MΩ·cm, essential for HPLC, LC-MS, ICP-MS, cell culture, and molecular biology workflows. What distinguishes Astacus² from standard systems is its dual water output design: it delivers ultrapure Type I water while also supporting Type II or III water generation with its integrated reverse osmosis and electrodeionization (EDI) modules. This makes it a complete water purification solution, eliminating the need for a separate feed water system. Built with advanced monitoring technology, the Astacus² features real-time resistivity, TOC (Total Organic Carbon), and temperature tracking, plus a smart cartridge management system. Its compact design, user-friendly touchscreen interface, and long-life consumables make it ideal for high-throughput labs requiring reliability and low maintenance.
