PerformR® centrifuge tubes combine reliable performance in major centrifuges with spin rates higher than many popular brands. The high-quality, lab certified, non-cytotoxic medical grade resin means users don't have to compromise their work with low-quality tubes. 

• ATP-, RNase/Dnase-, and endotoxin-free (non-pyrogenic)
• Black printed graduations and white writing spot
• Validated Sterilisation (ISO 11137) for use in Research and Medical labs
• Polypropylene USP Class VI resin
• Freezable to –80 °C, and autoclavable

They are designed for everyday centrifugation and storage needs. These tubes include large white solvent-resistant labeling areas and black easy-to-read graduations. They are available with either a flat cap that is easy to label, or a plug style cap for horizontal applications.

Racked tubes are packaged in a reusable, autoclavable, and freezable (–80 °C) polypropylene rack that inter-locks to allow you to create a workstation.

Tubes can be ordered with a flat cap that can easily be labeled or a plug style cap that includes a very deep sealing area. The flat caps are designed to allow an evaporation seal with ¾ turn for one-handed operation. And then a final ¼ turn will seal them liquid tight.
