qp-HBC

uniqprobe - HeartBeatCantilever – for ScanAsyst** and Peak Force Tapping**

NANOSENSORS qp-HBC AFM probes are designed for use in ScanAsyst® or PeakForceTapping™** in air. The qp-HBC probes are also compatible for contact and non-contact or soft tapping mode AFM imaging The combination of soft cantilever and fairly high resonance frequency enables stable and fast measurements with reduced tip-sample interaction.

The NANOSENSORS uniqprobe combines the well-known features of the other NANOSENSORS AFM probe series such as high application versatility and compatibility with most commercial SPMs with the additional advantage of a strongly reduced dispersion of force constant and resonance frequency.

The unsurpassed uniformity of the mechanical characteristics of the uniqprobe series is particularly important for applications, where a large number of probes with known and near identical force constants or resonance frequencies are needed.

Special handling information for NANOSENSORS™ uniqprobes

Due to their unique geometry the tips of the uniqprobes are more susceptible to tip damage by electrostatic discharge (ESD) than other Silicon-SPM-Probes.

Electric fields near the probe chip may lead to field evaporation which can blunt the tip apex of the probe tip. Therefore the NANOSENSORS™ uniqprobes are shipped in specially designed ESD-safe chip carriers.

NANOSENSORS™ recommends to their customers to take appropriate precautions to avoid tip damage due to electrostatic discharge when handling the probes. This can for example be done by using anti-electrostatic mats, wrist bands and tweezers.
