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.

Key Features

• 25 mL capacity – fills the gap between 15 mL and 50 mL tubes
• Shorter height & wider diameter – saves storage space and improves sample handling
• Compatible with 50 mL centrifuge rotors – no adapters needed
• 360° support rim – ensures secure fit in racks and rotors
• Printed volume graduations – clear markings from 5 mL to 2 mL
• High-speed performance – withstands up to 17,000 x g RCF
• Sterile & certified – RNase, DNase, and pyrogen free
• Reduced waste and freight costs – eco-friendly compact design

Five-O™ 5 mL MacroTubes^® - Opaque Black

The 5 mL Five-O MacroTubes take all of the conveniences of standard 15 mL 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. Additionally, the 56 mm length (vs. 120 mm for 15 mL tubes, greatly reduces the risk of contamination of pipettor shafts, allowing 1 mL or 5 mL tips to easily reach the bottom.

The foam racks are similar to the packaging normally associated with 15 mL tubes (upright with caps attached), but they require about 60% less storage space.

• Opaque Black Tube
• Compatible with standard equipment
• Centrifuge at up to 25,000 x g
• RNase, DNase & pyrogen free
• Unsurpassed Clarity
• Dual graduations at every 0.2 mL and 0.5 mL

TotalPure™ Metal Free Centrifuge Tubes

MacroTube® Vivid™ 5 mL Tubes

Sterile, Ultra-Clear Tubes with Vivid Printed Graduations.

MacroTube® Vivid™ tubes are designed for precision, visibility, and purity in every lab application. Made from ultra-clear polypropylene, these high-quality laboratory tubes feature bold, vividly printed graduations for easy and accurate volume measurement. Ideal for researchers and technicians who need reliable, contaminant-free performance, each tube is certified RNase, DNase, and pyrogen-free.

Packaged sterile in resealable bags, MacroTube® Vivid™ tubes provide convenience and contamination control. Each set is housed in snap-apart racks (2 x 25 tubes) for quick access, efficient organization, and minimized waste.

Key Features

• Vivid, easy-to-read printed graduations for precise measurement
• Made from ultra-clear polypropylene for superior sample visibility
• Certified RNase, DNase, and pyrogen-free
• Sterile tubes packaged in resealable bags
• Snap-apart racks (2 x 25) for convenience and storage flexibility

5 mL Snap-Cap MacroTubes®

• Compatible with standard equipment
• Easy-open flip top
• Syringe port in cap
• Unsurpassed clarity, virgin polypropylene
• Dual graduations (at every 0.2 mL and 0.5 mL)
• Certified RNase and DNase-free.

5 mL MacroTubes® scale up the conveniences of standard 1.5 mL tubes for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak-proof seal and can be opened (or closed) with one hand. The cap is designed to provide a secure seal from -86°C to 80°C.

They have the same diameter as standard 15 mL tubes for compatibility with centrifuge rotors, etc. They have replaced 15 mL tubes in many applications, reducing plastic waste, storage space, and shipping costs. Contamination of pipettor shafts can be eliminated because the tube length is short enough for standard 1 mL and/or 5 mL tips to reach the tube's conical bottom. The syringe port in the cap is useful not only for needle and syringe access but also for venting internal pressure that has built up due to incubation at higher temperatures.

Dimensions: 16.5 x 54 mm (not including rim and cap)
Maximum Centrifugal Force: 25,000 x g (when properly supported in the appropriate rotor)
