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

Made of tough, clear, specially formulated polypropylene, the 0.6mL, G-Tube microcentrifuge 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. Will withstand temperature ranges of -80 degreesC (-112 degreesF) to 121 degreesC(250 degreesF). Lid Closure The flat top lid forms an extra-tight seal that will not come open during processing. Yet, it's easy to open with thumb pressure or our handy Microtube Tool (Item #BP-4000.). Inscribing Patches All flat top tubes have a textured writing surface on top of the caps. The interior has the smoothest, most highly polished surface of any tube on the market. The walls are non-wettable, preventing liquids from adhering to the sides. Needle Access You can easily insert a needle through the target in the exact center of the lid..
