Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. These tubes ship non-sterile. For applications requiring sterility, autoclave per your validated protocol or select a pre-sterilized SKU.
What does the tethered cap design provide?
The cap stays attached to the tube body, enabling single-handed opening and closing while preventing lost or mismatched lids during repetitive pipetting.
Can these PPC tubes be frozen and centrifuged?
Polypropylene copolymer tolerates freezing for sample storage and withstands standard microcentrifuge speeds. Always confirm g-force ratings against your rotor specifications.
How many tubes come in one pack?
Each pack contains 1000 tubes per bag, supplied with attached tethered caps. Pricing shown is per 1000/Bag.
