Pincer Grip Wobble Stick - PG

UHV Wobble Stick

The Pincer Grip series allows small 14mm disk samples to be transferred inside the vacuum envelope. Mounted on a 70mm OD CF flange, the wobble stick utilises a flexible edge welded bellows to allow effective hand operated movements to be transmitted through the vacuum chamber. The PG series benefits from 4 preset jaw positions, each set at 90° intervals and is operated via a push button on the end of the wobble stick.
