New process is changing the way semiconductor products are produced

Simrit, a division of Freudenberg-NOK, introduced its new product line of chemical mechanical planarization (CMP) gaskets and membranes at the SEMICON West 2007 show in San Francisco (July 16 to 20, 2007).

"Simrit is excited to announce its new line of elastomer products for CMP processes," said Patrick Gi... (read more)

R3 Water Technologies provides cleaning for all industrial 4" and 8" reverse osmosis membranes. The normal operation of any RO unit degrades membranes by mineral scale, organic material, biological contaminates or metal oxides. Deposits build up on the membrane surface, forcing operation pressure higher, reducing the efficiency of your system.

The long-term health of your reverse ... (read more)

Despite their reputation as reactive components in propellant composites and some chemical systems, the use of perchloric acid and perchlorate salts in novel process chemistries as well as industrial and academic research is a well-documented activity. (read more)

The Ultra Mag® Flowmeter from McCrometer combines superior flow measurement accuracy in liquids, slurries and sludge with low maintenance and long-life to set a new standard for performance, ease-of-use and value. The Ultra Mag features a rugged NSF-approved epoxy liner that also provides outstanding electrical insulating properties. (read more)

The V-Tork is a point level switch for liquids, thick and turbulent fluids, as well as corrosive mediums and pastes (depending on viscosity). It is ideal for multiple-purpose processing where the probes must be compatible with a variety of process materials and process conditions. (read more)

Sierra's Innova-Switch™ flow and level switches represent the state-of-the-art in gaseous and liquid flow switching or liquid level control. The Innova-Switch is easy to install and adjust, giving reliable, low maintenance performance in the most demanding applications. (read more)

AWC C-234 is a concentrated liquid formulation designed for use as a low pH cleaner of polyamide thin film composite membrane surfaces. (read more)

The Hilco ceramic membrane system is an ideal way to lower your oily-water waste disposal costs. The filtration system utilizes high-velocity fluid "crossflow" across the face of the membrane. The oil-free water passes through the ceramic membrane while the oily waste is concentrated in a process reservoir. (read more)

Vibration limit switch for liquids, maintenance-free alternative to float switches. The Liquiphant T is a compact level switch that is ideal in places where access is difficult or space is limited. (read more)
