Frequently Asked Questions
Are these 0.5 mL microcentrifuge tubes sterile?
No. These tubes are supplied non-sterile. For applications requiring sterility, validate an in-house autoclave or irradiation step appropriate to your protocol before use.
What does the tethered cap design provide?
The cap stays attached to the tube body, reducing the risk of misplaced or mismatched closures during open-and-close workflows and improving single-handed operation at the bench.
What is the difference between PPC and standard polypropylene?
PPC is polypropylene copolymer, a resin grade offering good clarity and impact toughness. The spec for this product is PPC specifically, not homopolymer PP.
Can these thin-wall tubes be centrifuged?
Yes. They are designed for microcentrifuge use; the thin-wall construction aids heat transfer. Always confirm your rotor's rated g-force and use a matched adapter for the 0.5 mL format.
