Diamond Midi Centrifuge Tube, 5.0 mL, PP, Attached Snap Cap, Graduated, Sterile — 200/Unit
The Diamond Midi Centrifuge Tube bridges the gap between standard microcentrifuge tubes and larger conicals, offering 5.0 mL capacity in a compact polypropylene format. Engineered with an attached snap cap to prevent loss and cross-contamination, these sterile tubes suit sample aliquoting, cell pellet processing, and PCR reagent storage. Clear graduations support quick volume estimation at the bench.

Frequently Asked Questions
How many tubes come in one unit?
One unit contains 10 bags of 20 tubes each, for a total of 200 sterile 5.0 mL centrifuge tubes. The $66.00 list price is per unit.
Are these tubes sterile out of the bag?
Yes. The Diamond Midi tubes are supplied sterile and individually bagged in quantities of 20, allowing you to open one bag at a time to maintain sterility of the remainder.
What centrifuge speeds do these tubes support?
Polypropylene construction handles routine benchtop centrifugation. Confirm the maximum rated RCF against your rotor and specific protocol, as g-force tolerance depends on rotor type and load balance.
Does the attached snap cap seal securely for storage?
The integrated snap cap provides a positive closure that resists accidental opening and reduces sample loss. It is intended for storage and handling rather than long-term pressurized or freeze-thaw cycling beyond manufacturer guidance.
