Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. These tubes are supplied non-sterile and are intended for general laboratory sample handling, aliquoting, and storage where sterility is not required.
What is the benefit of the tethered cap design?
The cap stays attached to the tube body, reducing the risk of lost or mismatched caps and helping prevent cross-contamination during repeated open-and-close handling.
What material are these tubes made from?
The tubes are molded from natural high-density polyethylene (HDPE), which offers good general chemical tolerance and durability for routine sample storage.
How are the tubes packaged?
They ship 1000 tubes per bag, with each bag carrying lot numbers for traceability in regulated and accredited laboratory environments.
