Frequently Asked Questions
What does the amber tint protect against?
The amber PPC reduces light transmission, helping shield photosensitive samples such as fluorescent dyes, vitamins, and certain reagents from light-induced degradation during handling and storage.
Are these tubes sterile or autoclavable?
They ship non-sterile. As polypropylene copolymer (PPC) tubes, they tolerate standard autoclave cycles; validate your specific cycle in-house before use with sensitive protocols.
What is the benefit of the tethered cap?
The cap stays attached to the tube, preventing lost or mismatched closures during rapid open/close cycles and reducing cross-contamination risk in high-throughput bench work.
How are the tubes packaged and sold?
This single-variant product is supplied 1000 tubes per bag (1000/Bag) at the listed per-pack price.
