Water purification systems, Barnstead™ LabTower™ EDI

This system combines purification with EDI technology and storage in one. Users can conveniently dispense Type 1 water directly from the system while Type 2 water is accessible from the integrated 100 l reservoir, which is an ideal supply for lab equipment such as autoclaves.

• Unique system with pre-treatment plus polisher to produce both Type 1 and Type 2 water
• Compact, free-standing unit can be easily relocated with bottom-mounted rollers
• Validated 0,2 µm final filter with folded membrane can be autoclaved up to five times
• Standard UV photo-oxidation at 185/254 nm reduces organic compounds in the water to ultra-low levels as well as microorganisms and their metabolites
• Recirculation pump protects purified water in tank from bacterial growth during standstill
• RS232 interface with adjustable send-interval for safe data transfer of all measured data to a PC computer or log printer
• USP-compliant conductivity measurement with temperature compensation that can be switched on or off

EDI technology:
- Constant high efficiency of the ion exchange layer bed produces consistently high quality water
- No regeneration chemicals required and no disposal of cartridges, making this technology friendly for the environment
- High-purity water when it is needed with no waiting time

Type I water:
Resistivity at 25 °C: 18,2 MΩ•cm
Conductivity: 0,055 µS/cm
TOC: 1 to 5 ppb
