Siliconized 1.5 ml G - Tube- Flat Top Microcentrifuge Tube - 500 pk - Natural, 500PK

Made of tough, clear, specially 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. 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 (catalog #4000.). Inscribing Patches All flat top tubes have a textured writing surface on top of the caps. The tubes have an additional textured writing surface on the side of the tubes.. The tube is graduated from 0.1 to 1.5ml. 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..
