A rapid, efficient and foolproof Purge Valve for 100% replacement of air in reaction vessels with any desired gas (N2, H2, AR, Cl2, etc.). No mercury used, no reducing valve needed on gas source, no high vacuum source necessary. No need to watch manometers, hand control gas flow, or install warning systems to prevent accidents. Expensive gases are conserved because once purging is complete, the flow can be cut almost to zero. Available with tube connection to system or #15 O-ring joint connection.
A renewed version of RZ, RZII has hit the streets. Twin 5-spoke and uniform 10-spoke wheels have come together in a crossover design that's as daring as it is evolutionary.<br><br>At the wide angle end of the twin spokes, both spokes are scooped out at the joint, adopting an "advanced side-cut" for the first time. At the narrow angle end of the twin spokes, the stepped shape maintains the wheel's strength, even with the thin spoke design.<br><br>Standard designs are available in 17-19-inch sizes, with some sizes offering GTR designs that have even more concave spoke shapes. In the 18-inch size, built to meet the exacting demands of racing, a Super GTR design is available.<br><br>All wheels, regardless of color, have diamond-cut rim flanges and polished rings that clearly establish the new RZII model's identity.<br>
