2.5 mL Flat Bottom Sample Cups — Polystyrene, Red, 1000/Bag (127-0018-R10)
These 2.5 mL freestanding sample cups are molded from red polystyrene with a flat bottom for stable, rack-free bench-top handling, supplied non-sterile in bulk quantities of 1000 per bag for high-throughput clinical and research workflows. The freestanding flat-bottom design keeps cups upright during sample preparation and aliquoting, while the red color supports straightforward visual identification and sample organization across the laboratory.

Applications
- Color-coded sample organization and tracking across multiple sample sets or patient batches

- Specimen handling and short-term storage in clinical and research laboratories
- General liquid handling where a freestanding, no-rack cup simplifies workflow
- Bulk, high-volume processing where cost-effective disposable cups are preferred
Material & Chemical Resistance
Polystyrene provides the 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 or dissolve the material; polystyrene is also not autoclavable and should not be exposed to dry or steam heat sterilization.

Frequently Asked Questions
Are these sample cups sterile?
No — they are supplied non-sterile in 1000/Bag bulk packaging, which is appropriate for the majority of routine clinical and research dispensing applications that do not require sterile consumables.
Can these cups stand upright without a rack?
Yes. The flat-bottom freestanding design allows the cups to stand stably on their own during sample preparation, reducing the need for additional support equipment at the bench.
What types of samples are compatible with polystyrene cups?
Aqueous samples, standard biological buffers, and dilute aqueous reagents are well suited to polystyrene. Avoid acetone, alcohols above 70%, and aromatic or chlorinated solvents, as these are incompatible with PS and can compromise the cup's integrity.
