Frequently Asked Questions
Are these centrifuge tubes supplied with caps attached?
No. These tubes ship unassembled — natural PPC tubes and green screw caps are packed together but not pre-threaded, which speeds filling and capping in high-throughput workflows.
Are the tubes sterile?
Yes. Each 30 mL conical tube is supplied sterile, making it suitable for biological sample collection, cell work, and reagent handling without additional preparation.
What is the maximum recommended centrifugation force?
Maximum RCF depends on rotor type and tube support. Confirm the rated g-force on the package insert and ensure the tube is properly seated in a compatible adapter before spinning.
What does PPC mean for these tubes?
PPC is polypropylene copolymer, a resin offering good clarity and impact resistance across typical centrifugation temperatures. It differs from homopolymer PP and is the exact material specified for these tubes.
