Manipulator and sampleplates

General information

At STM lab we use a custom-made receiver on the manipulator in the PREP chamber of the experimental set up. This receiver allows for efficient and controllable sample heating/cooling but most importantly for direct sample temperature measurement via a K-type thermocouple (requires a custom sampleplate). The receiver is back-compatible with standard flat ScientaOmicron flag-style sampleplates, however, the vertical dimensions for any double-stage sampleholders may differ.

Sample mounting

We have a stock of standard Scienta
