Water Storage

The main concern when storing purified water is the degradation of water purity over time. Only a strict adherence to suitable reservoir materials, associated with careful design and appropriate protection against airborne contaminants, can ensure consistent water quality during storage.

30, 60 and 100 L PE Reservoirs

Polyethylene selected for minimal release of extractables.
Blow-molded technique associated with best material choice prevents biofilm formation.
Cylindrical shape minimizes surface area in contact with water.
Conical bottom allows complete cleaning and rinsing.
Purified water smoothly fed in at bottom of the reservoir prevents absorption of carbon dioxide.
UV – an essential feature to keep bacterial levels low.
Front valve for manual dispense of purified water.
Hermetically-sealed lid prevents air from entering the reservoir.
Large top opening allows cleaning during sanitization procedure.
Compact, space-saving design.


30, 60 and 100 L PE Reservoirs	SDS 200, 350 L Storage / Distribution Systems

SDS 200, 350 L Storage and Distribution Systems

Millipore SDS 200 and 350 liter reservoirs incorporate the most advanced technological developments and innovative features to guarantee consistent purity of the stored and distributed water.

Polyethylene reservoir ensures minimal release of organics and smooth inner surface prevents biofilm formation.
Conical bottom guarantees no dead volume and allows complete cleaning, draining and rinsing.
ASM (Automatic Sanitization Module) UV lamp easily added to minimize bacterial growth during storage.
Sanitary overflow in the unlikely event of water system malfunction.
Choice of vent filters to protect stored water against airborne contamination.
Sensor rod float switch for automatic reservoir refill.
Built-in pump option can distribute purified water to multiple locations.
Inlet and outlet connections and valves are all pre-plumbed for easy installation.

Automatic Sanitization (ASM) and Water Sensor)

254 nm low pressure mercury vapor UV lamp, selected for its germicidal effectiveness.
Pre-programmable intervals of 10 min/day automatic UV illumination for optimized efficiency.
Additional programmable and manual UV exposure possible to meet critical application requirements.
Up to 60 min/day of UV exposure for total Flexibility.
Choice of language display and real time clock for maximum convenience.
The ASM is available with an optional water sensor, which can isolate the water system from the main line should any leakage be detected. The ASM display will show the time and date water was detected along with instructions on how to use this function.

Advanced Protection Against Airborne Contamination

Air is contaminated by carbon dioxide, particles, micro-organisms, and volatile organic compounds that come mainly from the laboratory atmosphere itself. To protect the purified water from all these contaminants, Millipore has developed an advanced vent filter that includes:

Activated carbon to adsorb volatile organics (including lab solvents such as acetone, chloroform and methanol)
A soda-lime bed to remove CO2
A Durapore® hydrophobic membrane for particle and bacterial retention

This advanced vent filter is recommended for the protection of high-resistivity water, such as Elix product water, during storage. A standard 0.65 µm membrane vent filter is available to protect reverse-osmosis-quality water.
