MULTIPOLYMER COMPOUND

CYROLITE(R)CG-97 acrylic-based multipolymer compound is specifically formulated for medical device applications requiring maximum chemical resistance to lipids and PVC plasticizers. Reportedly, the compound is easily processable, transparent, impact modified, suitable for injection molding, and it outperforms lipid resistant polycarbonate. It should not yellow or show deterioration from sterilization at typical gamma irradiation levels, and can be sterilized with ethylene oxide gas.

Tees and couplings

These stainless steel tees are insert-style connectors designed for direct and secure connection of three quick-disconnect couplings. They reportedly eliminate the need for additional hose barb fittings or tubing extensions, resulting in easier sampling, mixing, and fluid transfer. With Class VI silicone O-rings, the chemical-resistant connectors should withstand repeated autoclaving.

Miniature valve

The X-Valve(TM) is reported to be the world's smallest pneumatic valve. Recommended for the medical, industrial, and analytical industries, it's a two-position, three-way digital valve that's only 8 mm in width-comprising the smallest overall footprint available. Fewer functional parts are used in the glass-reinforced PBT molded body, so tgere are fewer potential leak points. Operating pressures range from 0 to 30 psig, and its response time is 20 msec.

Electronic components

This company's capacitors and filters help to make up Bionics(R)Corp.'s CLARION(R)Multi-Strategy Cochlear Implants. In conjunction with a microcircuit implanted in the skull, they stimulate hearing nerve fibers at multiple locations within the ear to provide greater pitch discrimination, providing a close approximation to natural human hearing. Capacitors and filters are also recommended for pacemakers, neural and muscle stimulators, and defibrillators.

Airflow measurement

The AirGrid is a flexible hardware tool for mobile, multipoint air velocity evaluation in cleanrooms. To improve efficiency, the device takes four individual point readings simultaneously, and automatically computes average air velocity and volumetric flow in real time. The user can set up multiple cleanrooms, each having various zones and individual filters. Up to eight individual points can be stored per filter. The printout shows room, zone, and filter data.

Modular encoders

These RM encoders offer a slide mechanism for adjusting the gap and concentricity of the encoder disc during installation. After installation, with a single push on the slide, the hub and disc are released, reportedly eliminating friction and drag completely. Because the encoder hub is mounted on the shaft using a set screw, the encoder is said to perform well under temperature cycles. The 0.06-inch glass disc should also withstand heavy vibration. Encoders are available in 1.5 or 2.1 inch diameters.
