Diamond Midi 5.0 mL Centrifuge Tubes, Polypropylene, Graduated — 9 Options, Bag & Carton Packs
The Globe Scientific Diamond Midi 5.0 mL Centrifuge Tube bridges the gap between microcentrifuge and standard conical tubes, giving labs an ergonomic mid-volume format for sample prep, aliquoting, and short-term specimen storage. Molded from clarified polypropylene with printed graduations, these tubes support reliable centrifugation, accurate volume reads, and confident pipetting at the bench.

Frequently Asked Questions
Which options are supplied sterile?
SKUs 111580S and 111580BS are sterile, assembled-screw-cap tubes packed 20/bag with 10 bags per unit. The snap-cap colored tubes and natural PP options are non-sterile.
What is the difference between snap cap and screw cap options?
Attached snap caps (111578 series) offer fast single-handed access for high-throughput work, while separate or assembled screw caps (111580 series) provide a more secure seal for transport and storage.
Why choose the black light-blocking tube?
The Midnight light-blocking black tube (111578BLK) shields photosensitive samples — such as fluorophores, vitamins, and certain reagents — from light-induced degradation during processing and storage.
Are these tubes graduated?
Yes. All nine options feature printed graduations on the polypropylene body for quick visual volume estimation up to the 5.0 mL capacity.
