Stub handling tweezers

EM-Tec SEM stub-gripper tweezers are specially designed to securely grip SEM stubs and mounts, allowing them to be handled without touching them by hand. Ideal for clean handling and to avoid contamination issues.  The SEM stub gripper tweezers are made from anti-magnetic stainless steel and are cleanroom compatible. SEM stub-gripper tweezers can be used for:

• Grooved pin stubs with 12.7mm, 25.4, 19 and 32mm head diameters
• JEOL cylinder stubs with 9.5, 12.2, 25 and 32mm diameters
• Hitachi cylinder stubs with 15, 25 and 32mm diameters

SEM stub-gripper tweezers tips for the grooved pin stubs fit directly in the groove of the SEM stub –  the angle between tip and handle is 45°. SEM stub grippers for the cylinder stubs are designed to grip the SEM cylinder stubs from JEOL and Hitachi and the angle between tip and handle is 30°.
For the grooved Ø12.7 and Ø25.4mm pin stubs, there are also scissor-type SEM stub grippers available; they provide a stronger grip than the tweezer-style stub grippers. The scissor-type SEM stub grippers are made from anti-magnetic stainless steel.

SEM stub-grippers can also be use to pick up other types of samples with similar diameters as the SEM stubs. Metallographic embedded samples of 25mm and 30mm or 1” and 1-1/4” diameter can be handled or used when etching the surface of  samples. Substrate discs can be picked up at the edge.
