Samco Specimen Containers

Samco specimen containers from Thermo Fisher Scientific are a laboratory and collection-site staple for one reason: leak integrity. The Bio-Tite line was engineered so that once the screw cap is seated correctly, samples stay sealed through transport, centrifugation prep, and handling — a detail that matters when a spilled specimen means an uncollectible sample and an anxious patient asked to return.

Every container here ships sterile, disposable, and graduated, in the standard 90 mL (3 oz.) size that fits most urine, tissue, and general specimen collection protocols. The transparent body with a bright orange cap makes fill volume easy to read and lot handling easy to track across a busy bench.

Narrow-mouth vs. wide-mouth

The choice usually comes down to what's going in the container. Samco Narrow-Mouth Bio-Tite Containers (48 mm opening) suit routine liquid collection where a tighter aperture reduces spill risk. Wide-Mouth Bio-Tite Containers (53–55 mm openings) give you room for solid or semi-solid specimens, swabs, and easier transfer with a spatula or scoop. If your workflow spans both, the Samco Clicktainer with its 53 mm opening offers an audible click closure that gives collectors immediate confirmation the cap is secure — helpful when patients self-collect and closure technique varies.

Because these are polypropylene and high-density polyethylene, they hold up to a wide chemical range and cold storage without cracking. Sterility and single-use design keep them appropriate for diagnostic labs, physician offices, and point-of-collection sites where cross-contamination isn't an option.

When ordering, match the opening size to your specimen type first, then confirm your standing par level — these are high-turnover consumables, and running out mid-shift stalls collection. Browse the full Samco range above to compare closures and mouth sizes side by side.
