Frequently Asked Questions
What is the difference between the flared-top and sediment-bulb tubes?
Standard flared-top tubes (112011, 112015) offer a conical base for general spins, while the sediment-bulb variant (112030) features a tapered bulb graduated to 10 mL that traps sediment and simplifies controlled supernatant decanting.
Are these tubes compatible with Kova-style systems?
Yes. SKU 112015 is a Kova-type flared-top design intended to work with Kova-style decant and reading workflows. Confirm fit with your specific reading chamber or cap accessory before standardizing.
Are the tubes supplied sterile?
No. These polystyrene urine centrifuge tubes are supplied non-sterile, which is appropriate for routine urinalysis and sediment microscopy. They are single-use and should not be autoclaved.
How are the pack quantities sold?
SKU 112011 ships 500 tubes per case, 112030 ships 1500 per case, and 112015 ships as 1000/bag with 2 bags per unit (2000 tubes). Prices listed are per pack as the manufacturer sells them.
