ZWS UNIVERSAL WOBBLE STICKS MANUAL DN40CF 80-280mm TRAVEL

Product DESCRIPTION

Wobble sticks are devices that enable relatively simple movements to be transmitted through the wall of a vacuum chamber. Wobble sticks can be used as sample transfer devices; they are located at interchange points in the system where specimens must be moved from one device to the next (for example, from a loadlock insertion probe to a sample manipulator). Wobble sticks may also be used as actuators to operate mechanisms in vacuum such as shutters etc.There are three distinct type of wobble stick device:'Conventional' wobble sticks employ a single bellows and plunger mechanism (WS20) and have limited angular and linear motions.‘Universal' wobble sticks employ a double bellows and plunger arrangement which permits a much wider range of angular and linear travel (WS50/120/182/240). These are often used with a particular design of sample transfer arrangement to lift and carry samples within the vacuum system. Accessories are available for these wobble sticks which allow a sample transfer system to be designed around a standard transferable sample stub.'Double Acting' devices incorporate, in addition to the double bellows arrangement, a third bellows mechanism with a coaxial actuator. This arrangement (WS75/130PG) allows the wobble stick to be fitted with a device which can firmly grip samples which minimises the danger of samples being dropped during transfer.
