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

• A. Tweezers
• B. Cotton swab and sampling spatula
• C. Plastic scoop
• D. Paper funnel

Answer: (B)

Transferring a solid sample to a vial requires precise, contamination-free handling that minimizes loss. A sampling spatula lets you scoop a small, controlled amount, giving you direct, clean transfer into the vial. A cotton swab complements this by reaching into corners or collecting fine residues that a larger tool might miss, ensuring those traces are moved into the vial without spattering. Together, they provide both controlled bulk transfer and thorough pickup of residues.

Tweezers can be bulky and metal, risking contamination or reactions with some materials. A plastic scoop is good for larger transfers but lacks precision for tiny amounts and can leave residues. A paper funnel guides powder into a container but isn’t precise and can generate dust.
