The G-Tube™ is virtually transparent and far exceeds the toughness of any microcentrifuge tubes. When the G-Tube™ cap is closed there will be an audible "snap" that indicates a secure closure has been formed.
Made of tough, clear, propietarily formulated polypropylene, the G-Tube™ has the same chemical resistant quality as standard tubes but they're sturdier and virtually transparent to give a better view.
The flat top cap is easy to open and still provides a maximum secure seal. The G-Tube™ is built for high impact usage and will withstand over 30,000 x g when spun. Thicker walls make this the tube of choice for extreme stress, high spinning speeds, autoclaving, boiling, chemical resistance and freezing. The G-Tube™ will withstand temperature ranges of -80°C (-112°F) to 121°C (250°F).
