NITRA-TALL-R-G(AFM 探針)

NITRA-TALL-R-G probes are designed to image tall biological features. The tip and cantilever both are made of silicon nitride material. These probes are compatible with most commercial SPM/AFM instruments.

The following features make these probes unique for biological applications:

· Extra Tall Tip With High Aspect Ratio : Reduced artifacts when imaging tall biological features

· Integrated Laser Reflecting Pad : For optional gold reflex coating.

· Reduced Thermal Drift : Uncoated probes are not affected with

thermal drift ( bimorph effect) when imaging in liquid. This facilitates instant imaging without waiting to stabilize the probe in the solution.

· Chemical Functionalization: The silicon nitride material on the tips can be conveniently functionalized

NITRA-TALL-R-G Probe is a 2-in-1 probe chip with Two Rectangular cantilevers  With Gold reflex coating
