Offered as a cost-effective alternative to membranes on all-PTFE needlefelts, Tetratex membrane is an all-PTFE woven filtration medium available in roll format for bag manufacturers. Available in two configurations, the membrane accommodates the most demanding baghouse applications, such as air-pollution control and product recovery. Tetratex 7008 is tailored for applications where contamination of the product in contact with the medium may occur, while Tetratex 7012 is designed for hot-gas filtration applications where extreme chemical conditions are present.

Medica Pro systems can deliver up to 4 L/min of Clinical and Laboratory Standards Institute (CLSI) Type 1 water to single or multiple analyzers. Each compact system has an integral reservoir that eliminates the need for a separate tank, pump and pre-treatment filter. In addition, the reservoir and reduced rinse-up time allow for simpler and easier installation. The combination of ion-exchange resins in the deionization cartridge deliver long life and lower operating costs. Users have the option of adding a second cartridge to further reduce the exchange frequency.

Made for the laboratory, this water-purification system combines the vendor’s Elix Clinical system with a BioPak final filter to remove alkaline phosphatase (ALP), while providing prefiltration, softening, reverse osmosis (RO), electrodeionization (EDI), polishing and microfiltration in a single package. Elix facilitates water flowrates of 35 and 70 L/h, while the BioPak disposable ultrafiltration cartridge dispenses ultrapure water for up to three months without experiencing a loss of capacity.

The recovery of polyphenols and other extracts from green tea, fruits and various plants is difficult, due to the low concentration and complicated mixture of such materials. With Amberlite FPX ion exchange resin, these compounds can be selectively adsorbed and recovered with higher purity and increased yield. In one application with pomegranate feed, Amberlite FPX increased the polyphenol purity from 3% to 52%. The resin is FDA-compliant for use with food, and food-grade solvents are used to recover the purified extracts.

As the semiconductor industry moves to narrower linewidths, the demand heightens for filtration products that capture smaller fluid contaminants in the nanometer range. Among the nine new products launched by this filter maker are two that target single-wafer and batch-mode wet-chemical processing. The UltiKleen Excellar ER Filter is a 20-nm-rated, polytetrafluoroethylene (PTFE) membrane that offers superior non-dewetting in aqueous and high-viscosity chemical applications.

Graphlon GM 860 is tough, polymer/graphite-based, abrasion-resistant bushing material that prolongs the life of pump bushings and other critical-wear parts. It provides excellent abrasion resistance in harsh environments, and has been developed specifically for sump pumps and river water service pumps where abrasives are a problem. Traditional pump materials are prone to damage from highly abrasive suspensions, and traditional bushings, including bronzes and plastics, do not adequately handle run-dry situations.

A proprietary inorganic coating that facilitates the removal of gaskets from flanged joints, Flange Free is designed for use in high-temperature, critical-service applications. Gaskets treated with this material are easier to remove after extended use — in most cases, the effort takes seconds, not hours, and requires much less force than untreated gaskets. The coating is fused to the surface of the gasket material and does not contain chemicals that can cause gaskets to crack or otherwise degrade.

MasterSil 151 MED is a medical-grade potting and encapsulation silicone that is formulated to withstand vibration, impact, shock and thermal cycling. This two-component material cures at room temperature (more quickly at elevated temperatures), with cure shrinkage less than 0.1%, a Shore A hardness of 45, and an elongation-at-break of 160%. It cures optically clear with a refractive index of 1.43, making it well-suited as a protective coating in optical and fiber-optic applications.

Most uncoated photovoltaic (PV) panels lose about 4% of their potential power output due to surface light reflection. Honeywell SOLARC is a transparent coating material that improves light transmittance through the glass that covers PV panels, thus increasing the PV module’s efficiency and power output. This coating also significantly reduces glare from the glass, allowing the panels to better blend in with their surroundings. It is compatible with many coating processes, including spray, roller, curtain, slot-die and spin-on coating.

PUREX HS 45-RP is a high-performance black for mechanical rubber goods. It contains low polycyclic aromatic hydrocarbon (PAH) content, complying with Recommendation XXI of the Bundesinstitut f¸r Risikobewertung (Germany) and the ArrÍtÈ du 09.11.1994 (France) standards. It is similar to PUREX HS 45, with the -RP suffix signifying its reduced PAH content. It has a low specific surface area, giving it good processability, low die swelling, and high microwave absorption.
