HOW TO SAMPLE / Micro-tools

Learn the best ways to use our micro-tools for sampling during microscopic work with the hope that it enhances your operations and interest in our tools.

Case.1) Micro substances on the surface

< Sampling method >
To collect falling micro substances, use the sharp Tungsten Probe tip to touch and pick up the sample. A micromanipulator may be required based on the substance’s size and condition.

The sampling is possible due to the intermolecular (e.g. electrostatic forces) between the probe tip and the target substance.

<Tool selection notes>
Please select smaller or half size tips than the target substance.

< Recommended Micro-tool >
Tungsten Probe

Case.2) Partially embedded substances

< Sampling method >
Use the flat edge screwdriver-shaped tool’s tip to contact and excavate the target substance for sampling. A micromanipulator may be required based on the substance’s size and condition.

Use the tungsten carbide needle-shaped tool by pressing its tip directly onto the substance to extract buried or adhered samples.

<Tool selection notes>
Choose the appropriate tool shape for your target substance: flat edge screwdriver, knife-edge, probe, or fork.

< Recommended Micro-tool >
