Recently Eppendorf launched 5.0 mL Centrifuge Tubes as well as Plastic Cuvettes for measurements in visible range. When working with samples between 2 and 5 mL, researchers often have no choice but to use tubes that are really designed for larger volumes, typically 15 mL conical screw cap tubes. The new Eppendorf Tube 5.0 mL now provides the 'missing link' for such samples, delivering a high-quality solution for volumes up to 5 mL.

These new tubes feature a practical and convenient snap cap for single-hand operation and a compact conical design, removing the contamination risks associated with manipulating small volumes in large tubes. Eppendorf Tubes 5.0 mL are designed for safe and stable centrifugation up to 25.000 x g, eliminating the risk of sample loss when using rapid protocols. A new polypropylene material provides high transparency and minimizes leaching for safe and reproducible assay data. Introduction of 5.0 mL tubes will lead to 60 percent reduction in plastic waste!

The Eppendorf Vis Cuvettes are disposable cuvettes made of clear plastic with a light transmission of 300 nm to 900 nm. The visible cuvettes are perfect tool for applications outside the UV range, for example, colorimetric protein assays (Bradford, Lowry, etc.), determining optical density of bacterial cultures (OD600 methods) and kinetic and fluorescence measurements.
