Pincer Grip for JT-SPM V3

Product code: PGWMSJTAFM3

The PGWMSJTAFM3 was custom made for fetching and swapping both the sensors as well as sample plates of a Specs TytoTM Precision SPM Head.

It  was designed with easy handling in mind: From it's position for grabbing the released sensor, it takes just a 180° twist and it's at the correct level to fetch the sample plate. The V3 pincer has a larger offset compared to the V4 to match the older version of the SPM head.


For ultimately precise and safe handling, we recommend the PGWMSJTAFM3 be used in combination with a fine adjuster coupling equipped dual shaft wobblestick WMG40(FC)-XXXX-YYYY, as pictured below:
