The MTC Bio C2540-OB Five-O 5mL MacroTube Centrifuge Tubes with Attached Screw Caps, Sterile, Opaque Black, 16 x 64mm, 50 per Foam Rack, Pack of 500, take all of the conveniences of standard 15mL conical tubes and scale them down for space efficiency and decreased natural resource consumption. Useful from -86°C to 110°C, these tubes are a valuable resource for boiling and for sample preservation at very low temperatures.

The Five-O 5mL MacroTube tubes are made of high clarity, low-binding virgin polypropylene and are certified pyrogen, RNase, and DNase free. The tubes are supplied in gamma sterilized racked packaging with attached caps. The foam racks are similar to the packaging normally associated with 15mL tubes (upright with caps attached), but they require about 60% less storage space.
