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 or dissolve the material; polystyrene is also not autoclavable and should not be exposed to elevated temperatures.

Frequently Asked Questions
Are these sample cups sterile?
No — part number 127-0018-B10 is supplied non-sterile in 1000/Bag bulk packaging, making it well suited for general laboratory workflows where sterility is not required.
Will these cups stand upright without a rack?
Yes. The flat-bottom freestanding design allows the cups to stand independently on any level surface, which is convenient during sample preparation and pipetting steps.
What types of samples are compatible with polystyrene cups?
Aqueous samples, standard biological buffers, and dilute aqueous reagents are appropriate. Polystyrene is not compatible with acetone, alcohols above 70%, or aromatic and chlorinated solvents, which can damage or dissolve the material.
