Frequently Asked Questions
What is the working volume of these tubes?
Each tube holds 2.0 mL and is graduated to help estimate fill levels and aliquot volumes during sample handling.
Are these microcentrifuge tubes sterile?
No. These tubes ship non-sterile. For applications requiring sterility, autoclave compatibility depends on your validated cycle parameters for polypropylene copolymer.
What does "tethered cap" mean for these tubes?
The flat cap stays attached to the tube body via a tether, reducing the risk of misplaced caps and cross-contamination during one-handed opening and closing.
How are the tubes packaged and sold?
These tubes are sold in bags of 250. The listed price is per pack of 250/Bag, and each bag is lot-numbered for traceability.
