Atomic Force Microscopes SA-AFM AFM workshop

The SA-AFM is a flexible AFM for scanning all sizes and shapes of samples. A complete system for life sciences samples, large samples, routine scanning of technical samples, and nanotechnology research. The SA is easily integrated with inverted microscopes.

Open Frame Design	Any sized sample can be scanned
Includes bottom plate	Allows for scanning small samples
Probe Exchange Tool Included	Reduce time for probe exchange
Includes top view video microscope	Facilitates tip approach and laser alignment
Includes vibrating, non-vibrating, phase, LFM, and advanced F/D	Most common scanning modes included for many applications
Flexible Sample holder	Can be used with most commercially available probes
Labview software with USB communication	Readily adaptable to new operating systems
