    • Sample Navigation | June 2017

      State-of-the-art sample navigation

      After loading and initializing Tosca™ 400 first of all an overview image of the whole sample table can be started. In the second step the instrument automatically navigates to the sample of choice for the next measurement with just one mouse-click on the respective area in the overview image. This navigation is also available in the micro view. The navigation is triggered fully automatically by using the integrated video microscope. In this way you can even navigate to small features very easily.

      Keep track of your measurement area

      Due to the fact that the sample table of Tosca™ 400 with a diameter of 90 mm can hold either a single sample or multiple samples, an overview image becomes very important. In this way the user can quickly identify the measurement area of one sample or identify the different samples on the sample table. With the “overview image” function, an overview image of the entire sample area can be automatically captured within a short period of time.

      Polymer Surface Characterization on a Grand Scale | March 2017

      The surface properties of polymeric materials are central to their behavior in formulation and manufacturing processes, as well as in their target applications.

      Tosca™ 400 is a powerful tool for characterizing polymer surfaces at the nanoscale. It provides both surface morphology and also phase contrast between different components in polymer blends. Most importantly, even multiple samples can be handled easily by Tosca™ 400 due to the large sample table. Thanks to special automation features, you do not have to open the instrument cover at all to run multiple samples. Everything can be done by the Tosca™ control software.

      Automatic laser alignment | January 2017

      A very important but also quite complex step in the course of AFM measurements is the laser alignment. This can be quite time-consuming, not only for an inexperienced user. This is why Tosca™ 400 provides a fully automatic laser alignment function: After the loading of the cantilever onto the actuator body and the actuator body onto the AFM head, the instrument carries out the laser alignment automatically after just two clicks in the Tosca™ control software.

      Another benefit of this feature which saves time and money is the flexibility of using any available cantilever, independent of the manufacturer. As a consequence, expensive pre-aligned or pre-mounted cantilevers have become obsolete with Tosca™ 400.

      Quick warm-up | December 2016

      An integrated, intelligent energy-saving system turns off all components that don‘t influence system drifts due to warm-up phases. Therefore, Tosca™ 400 saves energy and can be used for measurements within a very short time without any drift effects.

      Auto settings adjustment | November 2016

      Tosca™ 400 provides a fully automatic scan parameter adjustment function which leaves the complicated parameter adjustment process to the instrument itself. By activating this function, the instrument can automatically adjust the scan parameters to record images with the highest quality. Tosca™ 400 is an AFM open to users of all experience levels.
