MTC™ Bio 25 mL Centrifuge Tubes

MTC™ Bio 25 mL Centrifuge Tubes are the perfect solution for applications requiring more volume than 15 mL tubes but less than 50 mL. Designed to close the gap between standard sizes, these mid-volume conical tubes are ideal for midipreps, sample preparation, centrifugation, mixing, and long-term storage.

With a 33% shorter height and a wide diameter identical to 50 mL tubes, these low-profile tubes enhance efficiency by allowing faster pellet re-suspension and 100% sample recovery, even with small volumes. Their unique design also helps prevent cross-contamination, thanks to a pipette-friendly, wide-mouth opening that reduces accidental contact with the inner tube wall.

Made of high-clarity polypropylene, each 25 mL tube can withstand up to 17,000 x g RCF (relative centrifugal force) and features a 360º support rim beneath the screw cap. This rim fits most standard 50 mL tube rotors, racks, blocks, and centrifuge shields, eliminating the need for adapters—similar to the convenience of 1.5 mL microcentrifuge tubes.

These conical tubes come gamma sterilized, are RNase, DNase, and pyrogen free, and are available in bags or racks of 25, with caps pre-attached for ease of use.
