.6 ml G - Tube- Flat Top Microcentrifuge Tube - 500 pk - Blue, 500PK

Color: Blue.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, proprietarily 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 degreesC (-112 degreesF) to 121 degreesC (250 degreesF).
