Microcentrifuge tubes are manufactured from siliconized polypropylene, which provides extremely low surface adhesion and enables maximum sample recovery.

• Withstand temperature ranges of –80 °C (–112 °F) to 121 °C (250 °F)
• Thicker walls for extreme stress, high spinning speeds, boiling, chemical resistance and freezing

These flat top microcentrifuge tubes have a textured writing surface on top of the caps. The flat top lid forms an extra-tight seal that will not open during processing, yet is easy to open with thumb pressure.
