What containers and tubes can be used for sample collection?

• A. Plastic, spun Teflon, or polypropylene
• B. Ceramic, quartz, and wood
• C. Glass, stainless steel, or copper
• D. Aluminum, nylon, or rubber

Answer: (D)

Choosing containers and tubes for sample collection hinges on material compatibility and practicality. Aluminum provides sturdy, lightweight containers that resist many environmental conditions, while nylon offers chemical resistance and flexible tubing options. Rubber components give reliable seals and gasketing, which helps prevent leakage and contamination. Together, these materials cover rigid containers, flexible tubing, and sealing components typical of field sampling kits, helping preserve sample integrity from collection to transport. In contrast, materials like glass or wood can be fragile or absorbent, and metals like copper may corrode with certain samples, making them less ideal for broad use in the field.
