Your cart is empty.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.

But I love these little tubes for traveling with small amounts of liquids: expensive moisturizers, perfume oils, etc. They stay securely fastened, don't leak, and don't take up any space at all.
