We offer a full range of metal catalysts in varying purities and concentrations that includes homogeneous catalysts, supported/unsupported heterogeneous catalysts and fuel cell catalysts for anodes, cathodes, electrodes.


Metal catalysts are extensively used both in the research laboratory and in industrial/manufacturing processes. Indeed, it is hard to find a complex synthetic reaction or an industrial process that does not, at some stage, require a metal catalyst.

Linear bearings generally use a pad, bushing, or roller system to carry a load on a rail that need not be a straight line. The rail can be most any length, although that dimension is limited by the actuator.


The durability of the bearing is determined by the load and required speed. Furthermore, rails can generally be any profile – simple flat surfaces, round polished rods, or complex profiles with polished ground surfaces on which balls or cylindrical rollers can ride. Hard (Rockwell 6 and ground bearing surfaces work best.

Packaging machines are used for the assembly of unit loads from sheet goods, from bulk goods in sacks, and from individual items in the metallurgical, printing, and wood-products industries. Such machines may be designed to assemble unit loads horizontally, vertically, or in a manner that combines horizontal and vertical operations. In machines designed for horizontal operation, the goods from the conveyor belt, guided by the distributor in accordance with the work plan, are conveyed into the collector.

Centrifugal Fans

The centrifugal fan was invented in 1832 by military engineer Lieutenant General Alexander Sablukov of the Russian Empire's Imperial Russian Army. Often called blowers, centrifugal fans vary differently from axial fans. The pressure of an incoming airstream is increased by a fan wheel, a series of blades mounted on a circular hub. Centrifugal fans move air radially - the direction of the outward flowing air is changed, usually by 90°, from the direction of the incoming air.

Polyethylene's toughness, immunity from corrosion, excellent resistance to chemicals and low weight have contributed to its continued appeal for use in situations where cost-effective and reliable piping systems are required such as activities like horizontal direct drilling.


High-density polyethylene, unlike polypropylene, cannot withstand normally required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (e.g. Ziegler-Natta catalysts) and reaction conditions.

Battery backup devices have varying degrees of backup ability. To determine how powerful a UPS you need, first, use the OuterVision Power Supply Calculator to calculate your computer's wattage requirements. Take this number and add it to the wattage requirements for other devices you'll plug into the battery backup. Take this totaled number and check with the UPS manufacturer to find your estimated battery runtime when you lose power from the wall.
