2.0 mL Freestanding Conical Bottom Sample Cups — Polystyrene, Red, 1000/Bag (127-0090-R10)
These 2.0 mL freestanding sample cups feature a conical bottom and are molded from red polystyrene, supplied non-sterile in bulk (1000/Bag) for high-throughput clinical and research workflows. The conical bottom geometry encourages sample pooling toward the tip, facilitating efficient aspiration of small volumes, while the freestanding base allows the cup to stand upright without a rack during sample preparation. Part number 127-0090-R10 is well suited to routine dispensing, aliquoting, and color-coded sample organization.

Material & Chemical Resistance
Polystyrene provides rigidity and dimensional consistency well suited to aqueous samples and standard biological buffers. As with all PS labware, avoid acetone, alcohols above 70%, and aromatic or chlorinated solvents, which can craze, cloud, or dissolve the material; polystyrene is also not autoclavable and should not be exposed to elevated temperatures.
Quality & Procurement
Made in USA, Caplugs® Evergreen sample cups are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin. LabSupplies.com is an authorized dealer and ships from USA inventory, typically same business day for stocking items, with tiered pricing available for institutional and grant-funded laboratories.
Frequently Asked Questions
Are these sample cups sterile?
No — they are supplied non-sterile in 1000/Bag bulk packaging, making them suitable for general laboratory and clinical applications that do not require a sterility guarantee.
What is the advantage of a conical bottom over a flat bottom?
A conical bottom concentrates liquid toward the tip of the cup, which helps ensure more complete aspiration of small sample volumes and reduces dead volume during pipetting.
Can polystyrene cups be used with organic solvents or autoclaved?
No on both counts. Polystyrene is incompatible with acetone, alcohols above 70%, and aromatic or chlorinated solvents, and it is not autoclavable. These cups are intended for aqueous samples and standard buffers under ambient conditions.
