The BL-AC70N-PSA is a high-performance silicon nitride bio cantilever designed for tapping mode AFM imaging in air or liquid environments. This probe offers a balanced combination of sensitivity, stability, and gentle sample interaction, making it ideal for biological and soft-material applications.

The BL-AC70N-PSA is particularly well suited for imaging cells, biomolecules, hydrogels, polymers, membranes, and other soft or fragile samples where low-force operation is essential.
