5mL MacroTubes™ scale up the conveniences of standard 1.5mL tubes for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak proof seal, and can also 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 15mL centrifuge tubes for compatibility with 15ml centrifuge rotors, using the Adpater Inserts. In many applications, they have replaced 15mL tubes, reducing plastic waste, storage space and shipping costs. Contamination of pipettor shafts can be eliminated becasue the tube length is short enough for standard 1mL and/or 5mL tips to reach the tube's conical bottom.
Dimensions SnapCap Tubes: 16.5 x 54mm (not including rim and cap) Maximum Centrifugal Force: 25,000xg*
SnapCap Tubes are compatible with standard equipment. Feature easy-open flip top hingecap or screwcap, syringe port in cap, unsurpassed clarity, and dual graduations at every 0.2mL and 0.5mL.

Non-Sterile, 5ml Five-O™ ScrewCap Macro Centrifuge Tubes
Non-Sterile 5mL Five-O™ tubes take all of the conveniences of standard 1.5mL tubes and scales them up for larger volume and throughput. These screw Cap Tubes are supplied with 20mm (OD) caps that seal smoothly and completely with a single 360° turn. Useful from -86°C to 110°C, they are a valuable resource for boiling and for sample preservation at very low temperatures. Choose from non-sterile bulk packaging with separate caps or gamma sterilized rack packaging. 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.
The 16mm tube diameter is identical to the diameter of standard 15ml tubes, which ensures further compatibility with centrifuge rotors, etc. In many applications, these tubes have replaced 15ml tubes, dramatically reducing plastic waste, storage space and shipping costs. The potential contamination of pipettor shafts is greatly reduced because the 56mm total tube length (vs. 120mm for standard 15ml tubes) is short enough for standard 1ml or 5ml tips to reach the tube’s conical bottom.
These non-sterile 5ml tubes (C2530) are made of maximum clarity, low-binding virgin polypropylene and are certified RNase & DNase free. Note, sterile tubes (C2540) are also pyrogen free. These 5ml are sized to be compatible with all Benchmark™ (USA) and standard German-designed equipment, including our centrifuge (C2595) and others, dry bath block heaters, tube racks and thermal shakers/vortexers.
NOTE for ScrewCap Tubes: The 5ml Centrifuge Tube is Autoclavable (made of polypropylene). The 5ml ScrewCap is Not Autoclavable (made of polyethylene).
