2.0–2.5 mL Round Bottom Sample Cups — Polystyrene, Red, 1000/Bag (127-1212-R10)
These 2.0–2.5 mL freestanding round bottom sample cups are molded from polystyrene and supplied non-sterile in bulk (1000/Bag) for high-throughput clinical and research workflows. The freestanding round bottom design provides stable upright placement during sample preparation and aliquoting without requiring an external rack. Described by the manufacturer as Hitachi® Sample Cups, they are intended for use in compatible automated clinical analyzer applications; confirm fit with your specific instrument model before ordering.

Material & Chemical Resistance
Polystyrene offers rigidity and dimensional consistency well suited to aqueous samples, standard biological buffers, and serum-based specimens. As with all PS labware, acetone, alcohols above 70%, and aromatic or chlorinated solvents should be avoided, as these can craze, soften, or dissolve the material. Polystyrene is not autoclavable and is intended for single-use applications.

Frequently Asked Questions
Are these sample cups sterile?
No — part number 127-1212-R10 is supplied non-sterile in 1000/Bag bulk packaging, which is standard for high-volume automated analyzer and general laboratory use.
What does "freestanding round bottom" mean for everyday lab use?
Freestanding means the cup is designed to stand upright on its own on a flat surface without an external rack or holder, supporting efficient bench-top sample handling. The round bottom profile matches the geometry required by compatible automated sample cup positions.
What types of samples are appropriate for polystyrene cups?
Polystyrene is well suited to aqueous samples, serum, plasma, and standard biological buffers. It is not compatible with acetone, alcohols above 70%, or aromatic and chlorinated solvents, and should not be autoclaved.
