The mini vice with a 4mm slot is intended for clamping AFM/SPM samples at 90 degrees to enable easy imaging of cross section or sides of a sample. The sample is securely held by a small set screw. This method is quicker and keeps the sample and holder free from adhesives. It’s made from magnetic stainless steel (alloy 430). Can be used for samples up to 4mm or for multiple thinner sample clamped against each other and on AFM/SPM systems which include a magnet in the sample stage
