Corning, 352052, Falcon® 5 mL Round Bottom Polystyrene Test Tube, without Cap, Sterile, 125/Pack, 1000/Case

These clear polystyrene round-bottom tubes are intended for routine laboratory sample handling, cell suspensions, and compatible flow-cytometry workflows. Each tube has a 5 mL nominal capacity and is supplied without a cap. The round-bottom geometry helps with sample mixing and aspiration. The package contains 125 tubes per pack and 1,000 tubes per case. The sterile, disposable format reduces the need for cleaning between samples. Polystyrene is best matched to compatible aqueous solutions rather than aggressive organic solvents. Laboratories can use these tubes for aliquoting, staining, and short-duration sample handling when a small, transparent vessel is required.
