Caplugs® Evergreen 0.5 mL Graduated Conical Microcentrifuge Tubes, Tethered Cap, Thin-Wall, Amber PPC, 1000/Bag
The Caplugs® Evergreen 0.5 mL Graduated Conical Microcentrifuge Tubes deliver reliable, light-protected sample handling for DNA/RNA storage, enzyme aliquoting, and PCR reagent prep. Molded from polypropylene copolymer (PPC) in an amber tint, these thin-wall tubes shield UV- and light-sensitive analytes while integrated tethered caps keep closures attached during high-throughput bench work.

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, with lot numbers on each bag for traceability.
