Urine Centrifuge Tubes, 12 mL, Polystyrene with Sediment Bulb & Flared Top, Graduated to 10 mL — Case of 500
The Globe Scientific 12 mL Urine Centrifuge Tube is purpose-built for routine urinalysis, combining a tapered sediment bulb that concentrates cellular material at the tube base with a flared top for clean pour-off. Clarity-grade polystyrene supports microscopic examination of spun sediment, while the molded 10 mL graduation aids consistent aliquoting before centrifugation and decanting.

Frequently Asked Questions
Are these urine centrifuge tubes sterile?
No. These polystyrene tubes are supplied non-sterile, which suits routine urinalysis and sediment microscopy where sterility is not required.
What does the sediment bulb do?
The tapered bulb at the base concentrates spun cellular material into a defined pellet, making decanting and sediment recovery more consistent for microscopic review.
Why polystyrene rather than polypropylene?
Polystyrene offers high optical clarity that aids visual reading of sediment levels and graduations. It is best paired with aqueous samples; avoid strong organic solvents.
How many tubes are in a case?
SKU 112030-500 is sold as a case of 500 tubes at the listed per-case price.
