These disposable sterile tubes can be used for most routine laboratory procedures. They are biologically inert and exempt from mold release agents. Precision molding with virgin thermoplastics ensures that our tubes will be uniform in size and shape. High resistance to breakage reduces danger in handling infectious or other potentially harmful cultures.
Transparent polystyrene tubes will withstand moderate centrifugation speeds (1400g) and temperatures to 70°C. Translucent polypropylene tubes can be centrifuged at higher speeds (3000g) and resist temperatures from -190 °C to 120 °C.
