4.0 mL Conical Bottom Freestanding Sample Cups — Polystyrene, Blue, 1000/Bag (127-0066-B10)
These 4.0 mL freestanding sample cups feature a conical bottom profile and are molded from blue polystyrene, supplied non-sterile in bulk (1000/Bag) for high-throughput clinical and research workflows. The freestanding base allows cups to stand upright without a rack during sample preparation, while the conical bottom aids in concentrating small liquid volumes and facilitating complete aspiration. Part number 127-0066-B10 offers a practical, economical solution for routine sample dispensing and aliquoting.

Material & Chemical Resistance
Polystyrene provides good clarity and rigidity, making it well suited for aqueous samples and standard biological buffers. As with all PS labware, exposure to acetone, alcohols above 70%, and aromatic or chlorinated solvents should be avoided, as these can craze, cloud, or dissolve the material. Polystyrene is not autoclavable and is intended for single-use, non-sterile applications.

Frequently Asked Questions
Are these sample cups sterile?
No — part number 127-0066-B10 is supplied non-sterile in 1000/Bag bulk packaging, suitable for general laboratory use where sterility is not required.
What advantage does a conical bottom provide over a flat bottom?
A conical bottom helps concentrate liquid toward a single point at the base, which can improve complete aspiration of small or precious sample volumes and reduce residual dead volume.
Can these cups be used with organic solvents or autoclaved?
No — polystyrene is not compatible with acetone, alcohols above 70%, or aromatic and chlorinated solvents, and it cannot be autoclaved. These cups are intended for aqueous samples and standard aqueous buffers only.
