The G-Tube Flat Top Microcentrifuge Tube is virtually transparent and far exceeds the toughness of any microcentrifuge tubes.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.

These natural-coloured microcentrifuge tubes feature a flat top cap which provides a positive and secure seal when closed, thus providing maximum protection for contents. Fabricated with virgin polypropylene for excellent chemical resistant qualities and good clarity. These tubes have high impact strength and will withstand 17000RPM and 13000 x g centrifugation.
