High Precision Actuator Dual Shaft Wobblestick Wide Angle DN40CF

Product code: WMGWA40(FC)-XXXX-YYYY

Essentially identical to the normal dual shaft wobblestick, the WA-models are suitable for situations where wide angular range is important. However special care has to be taken to ensure that the welded bellows and the shaft of the wobble stick do not strike the tube or chamber walls, i.e. a very short oversize CF40 should be provided for the installation. If in doubt, please contact us for detailed information on this subject.
The fine adjuster magnetic coupling allows a precise control of the opening/closing of the pincer grips. A variety of pincers are available for almost any type of sampleholder. Please visit the Wobblestick accessories section for additional information.
Dual shaft wobblesticks wide angle are fully rotateable and allow for an angular deflection of +/-28 degrees.
