AFM cantilever tweezers
Micro-Tec AFM/SPM cantilever tweezers are useful tools for securely and easily picking up AFM and SPM cantilevers.
AFM/SPM tips are mostly supplied in Gel-Pak boxes and need to be gently lifted of the adhesive layer. The specially formed tip enables gripping at the side of the cantilever and pulling the silicon cantilever from its packaging. They are available in anti-magnetic stainless steel and titanium in the same design with a length of 118mm. Both materials are clean-room compatible.
- Anti-magnetic stainless steel AFM/SPM tweezers are intended for standard AFM / SPM cantilevers/tips and standard applications. Satin polished surface. Not recommend for use in or near magnetic fields.
- Premium titanium light-weight, fully non-magnetic AFM / SPM tweezers especially made for magnetic tips and for those users who prefer lighter cantilever tweezers. Matt blue anodized surface.
50-040001 Micro-Tec AFM / SPM cantilever tweezers
The material used for manufacturing 50-040001 Micro-Tec AFM/SPM cantilever tweezers is a selected grade of non-magnetic AISI 304.
- AISI 304 is an austenitic stainless steel (DIN 1.4301, X 5CrNi 18-10) and is the most common type of stainless steel
- Contains 18-20 wt% chromium and contains significant amounts of nickel as an additional alloy component
- Normally non-magnetic, but becomes slightly magnetic when cold worked
- Cannot be hardened by heat treatment
- Can be work hardened –Â annealing is recommended for relieving stress
- Good corrosion resistance to most solvents, salts and moderate acids
- Generally used where corrosion resistance is a requirement
- Typical applications include microscopy, electronic industry, fine mechanics and laboratory
