The MTC Bio C2500-AST 5mL Snap-Cap MacroTube Centrifuge Tubes, Non-Sterile, Assorted Colors, 50 per Bag, Pack of 200, 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.

The Snap-Cap MacroTube have the same diameter as standard 15mL tubes for compatibility with centrifuge rotors, etc. In many applications, they have replaced 15mL tubes, reducing plastic waste, storage space and shipping costs. Contamination of pipettor shafts can be eliminated because the tube length is short enough for standard 1mL and/or 5mL tips to reach the tube's conical bottom.

The tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase and DNase free.
