Hach, EZ9250.XX070001, EZ9250 Microfiltration System, for bypass, pore size 0.04 µm

Self-cleaning microfiltration system - compatible with EZ1000 and EZ2000 colorimetric analyzers
About the EZ9000 Series
The successful implementation of online analyzers in process control strategies could not have been achieved without the development of a new generation of automatic sampling and sample preconditioning systems. The EZ9000 Series are the result of many years of field experience in combining analyzers with filtration units.
Simplified operation by self-cleaning action
All preconditioning systems are designed for fully automatic operation and require virtually no human intervention. A blowback action by instrument air is incorporated in all systems. This fundamental design principle does not merely allow trouble-free sampling, moreover it contributes to high up-times.
The EZ9250 is a filtration system designed especially for colorimetry applications where absorbance interference may present an issue. The unit uses a hydrophilic PES membrane that wets out quickly and with a large effective membrane surface for superior flow rates. The membrane preferably sits in a buffer container mounted on the filtration panel. Prime features include:
- Membrane filter with pore size <1 µm designed for immersion in a buffer container, also directly (in situ)
- Automatic cleaning by instrument air
- Static Pressure Regulator assures a constant, readily available sample level
- PLC or analyzer controlled cleaning frequency
