100ml PPCO Centrifuge Tubes with Screw Cap is made from PP-copolymer tube body with PP screw cap. 
PPCO is more resistant to chemicals than PC.
The translucent polypropylene copolymer tubes also feature excellent mechanical strength. 
Autoclavable. 
When wet, the translucent test-tube enables observation of the contents. 
Can be used in refrigerated and unrefrigerated centrifuges at up to 50,000xg rcf. 
Accessory sealing cap assemblies are available for all sizes.
Bulk Centrifuge Tubes are available sterile or non-sterile, with flat-top caps or plug-seal caps.
Features:
Greater chemical resistance than polycarbonate
Can be autoclaved repeatedly - last longer than polycarbonate tubes under conditions of repeated autoclaving
Can be used up to 50,000 x g in refrigerated or non-refrigerated centrifuges; 
50ml PPCO Centrifuge Tubes can be used up to 100,605 x g if equipped with a sealing cap
Come with polypropylene linerless closures - easy to clean and provides leak proof protection under normal conditions up to 10,000 x g
For leakproof assurance at speeds >10,000 x g use with sealing cap assembly (sold separately)
Leakproof construction ensures more secure storage of samples
