What is used to transport a solid sample to the sample vial for the TruDefender?

• A. Plastic Pipette
• B. Cotton Swab & Sampling Spatula
• C. Glass Rod
• D. Metal Tongs

Answer: (B)

Transferring a solid sample to the TruDefender vial relies on a tool that can reliably pick up and deposit solids without scattering or contaminating the material. A cotton swab paired with a sampling spatula fits this need perfectly: the swab can lift residue from surfaces or powders, while the spatula can scoop and guide the material into the vial, giving you controlled, representative transfer and helping maintain sample integrity.

Other tools aren’t as well suited for solids. A plastic pipette is designed for liquids and would struggle to transfer dry particles cleanly. A glass rod is rigid and awkward for collecting fine solids, risking incomplete transfer or contamination. Metal tongs are bulkier and prone to damaging the sample or introducing metal contamination, and they don’t offer the same precise control for depositing into the vial.
