Frequently Asked Questions
What material are these 2.5 mL sample cups made from?
They are molded from natural (clear) polystyrene, a rigid, optically clear plastic well suited to short-term sample handling and visual fill checks. Polystyrene is not intended for use with aggressive organic solvents.
Are these sample cups sterile?
No. These cups are supplied non-sterile, which suits routine clinical chemistry, aliquoting, and reagent staging. If you require sterile consumables, select a validated sterile product instead.
What does the freestanding flat-bottom design provide?
The flat bottom lets each cup stand upright independently on the bench or in compatible racks, helping keep small 2.5 mL volumes stable for consistent pipetting and fill levels.
How are these cups packaged and sold?
They are sold by the bag of 1000 cups, priced per pack. Bags carry lot numbers for traceability, and tiered institutional pricing is available for larger orders.
