2.0 mL Conical Bottom Sample Cups — Polystyrene, Blue, 1000/Bag (127-0090-B10)
These 2.0 mL freestanding sample cups feature a conical bottom 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 geometry facilitates efficient liquid recovery and minimizes sample residue. Part number 127-0090-B10 is a reliable, cost-effective choice for routine specimen handling and aliquoting tasks.

Applications
- Routine sample aliquoting and dispensing at the bench

- Efficient low-volume liquid recovery where conical geometry reduces residual volume
- General liquid handling workflows requiring a stable, freestanding cup
Material & Chemical Resistance
Polystyrene offers clarity and rigidity 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 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 well suited for general laboratory applications where sterility is not required.
What is the advantage of a conical bottom over a flat bottom?
A conical bottom concentrates liquid toward the lowest point of the cup, which improves recovery of small sample volumes and reduces the amount of residual liquid left behind after aspiration or pipetting.
Can these cups be used with organic solvents or autoclaved?
No on both counts. Polystyrene is not compatible with acetone, strong alcohols, or aromatic and chlorinated solvents, and it is not autoclavable. These cups are intended for aqueous samples and standard aqueous buffers.
