DNP

Product Description:

A wafer of Silicon Nitride Probes
Premium Contact Mode or Fluid TappingMode imaging and force measurement probes.  Unmounted for BioScope / Dimension AFMs.
Quantity=380
*Due to the inherent danger of mishandling or contamination during extraction of probes by non-Bruker personnel, we do not guarantee performance of wafers once opened at the consumers site.  Instead, we highly recommend buying in larger quantities of 10-packs to guarantee performance, taking advantage of bulk discount pricing.
