Eppendorf introduces new tube system to aid in sample preparation and storage

July 3, 2013

Eppendorf North America has unveiled its Tube 5.0 mL, which company representatives say “fills the volume gap in sample preparation and storage.” According to Product Manager Matthew Lieber, “When working with samples between 2 mL 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 provides the ‘missing link’ for such samples, delivering a high-quality solution for volumes up to 5 mL.”

The Eppendorf Tube 5.0 mL is made from a highly transparent polypropylene to enhance visibility of pellets, and features a snap cap for single-hand operation. It has precise lid sealing designed to minimize sample evaporation, and a hinged lid to prevent accidental opening from -86°C to 80°C. (For higher temperatures, the Tube Clip can be used to eliminate the risk of lid opening.) The product has the same diameter and bottom shape as a 15-mL conical tube and a large frosted lid and surface on the side, it is autoclavable when open, and it is available in Protein LoBind and DNA/RNA LoBind material to reduce sample loss. It was manufactured without the use of slip agents, plasticizers, and biocides—substances that have been shown to leach from plastic consumables into the sample and negatively affect bio-assay results.
