G-Tube® Flat Top Microcentrifuge Tubes

The G-Tube® Flat Top Microcentrifuge Tube is virtually transparent and far exceeds the toughness of any microcentrifuge tubes. When the G-Tube Flat Top Microcentrifuge Tube cap is closed there will be an audible "snap" that indicates a secure closure has been formed.

Made of tough, clear, proprietary formulated polypropylene, the 0.6mL, 1.5mL and 2.0mL 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. All three volumes are available in siliconized material. Siliconized G-Tubes are not recommended for autoclaving.

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. Will withstand temperature ranges of -80°C (-112°F) to 121 °C (250°F).
