Frequently Asked Questions
Are these sample cups sterile?
No. These cups are supplied non-sterile and are intended for routine analytical, dosing, and aliquoting tasks that do not require a sterile vessel.
What material are the cups made from?
The cups are molded from polystyrene (PS), a rigid, optically clear plastic well suited to aqueous samples and short-term aliquot handling.
Why does the cup have a round bottom yet stand on its own?
The cup combines an interior round-bottom profile, which aids complete sample draw-down, with a freestanding base that holds the cup upright on flat surfaces during loading and pipetting.
How many cups come in a pack?
Each pack contains 1000 cups per bag, sold at one price per bag.
