SA025 Series

A1, A2, A3 (Cone Angle): A1 is the smallest, A3 is the biggest.
CR ( Curvature Radius): CR50 means tip apex curvature radius is 50nm, total diameter is under 100nm.

Example:

MSCT-SA025TPL013TC025A1-CR20

It means
•SA025 series and Wire diameter is 0.25mm
•Total probe length (TPL) is 13mm
•Taper cone length (TC) is 2.5mm
•A1 cone angle type.
•Tip apex curvature (CR) is 20nm, diameter is under 40nm
