Diamond Midi Centrifuge Tube, 5.0 mL, Graduated PP with Attached Locking Snap Cap, 500/Case
The Diamond Midi Centrifuge Tube bridges the gap between microcentrifuge and 15 mL conical formats, giving bench scientists a clear 5.0 mL polypropylene vessel for sample concentration, reagent aliquoting, and nucleic acid workflows. Graduations support quick volume reads, while the attached locking snap cap reduces lost lids and contamination risk during high-throughput prep.

Frequently Asked Questions
Are these 5.0 mL tubes certified RNase- and DNase-free?
Yes. Each lot is certified free of RNase, DNase, and pyrogens, making the tubes suitable for sensitive nucleic acid and molecular biology applications.
What maximum centrifugal force can the tubes withstand?
Rated g-force varies with rotor and adapter configuration. Polypropylene midi tubes typically tolerate moderate-speed spins; confirm limits against your centrifuge documentation before use.
Does the cap stay attached during processing?
Each tube has an attached locking snap cap that secures closed, reducing the risk of lost lids and cross-contamination throughout sample handling.
How many tubes come per order?
SKU 111582LK is sold by the case of 500 tubes at the listed per-case price.
