Organic Solvent Resistant (OSR) Bottles and Tubes

These products are to be used with organic solvents in the centrifuge at your own risk.

OSR Treated Tubes

These tubes are thick walled Delrin(1) tubes available in several sizes for use in a range of fixed angle-rotors. These tubes are resistant to many organic solvents at ultracentrifugation conditions and have found to be useful in nano particle resaerch applications.

Precision srcew threads have been formed on the outside surface of the tube wall and do not interfere with sample loading or retrieval. A one-piece anodized aluminum cap is screwed onto the tube and a Viton (2).

O-ring is encapsulated in a cap recess to provide a reliable seal. The caps have no fill hole and setscrew; the tubes are opaque and cannot be punctured or sliced. These tubes must always be used with a cap and must be full. They should not be autoclaved but can be sterilized by treatment with ethylene oxide gas or by cold methods (3).
