November 2008 Editor's Picks: Products from ResistoPure and Millipore

ResistoPure
Hose eliminates entrapment
The “Stratus” PTFE-lined silicone hose from ResistoPure (Marion, NC) features a flared-through design that eliminates the potential for entrapment. The hose incorporates one continuous piece of PTFE liner that is formed over the fitting ends. All of the hose’s wetted parts also are PTFE, which enables it to withstand steam cleaning and harsh cleaning solutions as well provide extended service life and a low cost of ownership.

In addition, because PTFE is a nonstick, low-friction material, it improves the hose’s drainability and reduces the potential that cleaning chemicals will contaminate high-value process streams.
The lightweight, flexible hose is appropriate for pharmaceutical and biopharmaceutical applications. The Stratus hose is available in diameters from 0.5 to 2 in.

Millipore
System purifies water efficiently
The “Elix Advantage” water-purification system from Millipore (Billerica, MA) incorporates an ergonomically designed “E-POD” water dispenser that provides pressurized pure water on demand. Unlike traditional deionization systems, the Elix Advantage system uses a small electrical current to continually regenerate the resins in the Elix module. The E-POD provides manual and volumetric dispensing at flow rates as high as 2 L/min. The unit’s graphic display shows information such as water quality and system status.

The system recirculates water from the storage vessel to the final dispensing point and back, treating it with ultraviolet light before it is stored in a reservoir. Various point-of-use filters can be installed in the E-POD to further purify water for specific applications.

The Elix Advantage system recycles reject water across its reverse-osmosis membrane, thus reducing the amount of tap water needed to produce pure water and extending the life of pretreatment cartridges. The system uses 200 times less electricity than conventional distillation equipment, according to the company.
