Sartorius Stedim Biotech
Ultrapure Water Systems arium® pro

ASTM type 1 water purification systems for routine analysis or critical applications where reagent-grade water is required. Intuitive menu navigation, operator-friendly setup, easy operation and high flexibility for producing laboratory-grade purified water.
  • Glass operator interface with touch function.
  • Time-controlled dispensing.
  • Freely adjustable flow rates up to 2 l / min (2 bar pressure, without final filter).
  • Conductivity measurement for feed and product water.
  • Integrated monitoring of water consumption.
  • Activatable PIN code for basic configurations.
  • Service and alarm functions supported by graphic displays.
  • Intelligent alarm system.

Areas of application:
  • Atomic absorption (AA).
  • Ion exchange chromatography (IC).
  • High performance liquid chromatography (HPLC).
  • Polymerase chain reaction (PCR).
  • Inductively coupled plasma mass spectrometry (ICP-MS).
  • Preparing cell culture media.
  • Protein purification.
  • Manufacturing reagents.
  • Preparing buffers and media.
  • Rinsing glass vessels.

Items supplied:
  • Wall-mounted systems: with front bottom-mounted display / dispenser unit and integrated wall bracket for the system.
  • Bench-top systems: with front top-mounted display / dispenser unit.
  • Built-in systems: incl. wall mounting kit for the display / dispenser unit with 2.8 m extended cable, tubing and wall bracket.
