The Siliconized 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, boiling, chemical resistance and freezing. This series can withstand temperature ranges of -80 to 121°C (-112 to 250°F).

The Hexa-Flex liquid-tight seal ensures sample integrity and prevents spillage of serum samples. Hexa-Flex Safety Caps are available in a variety of colours which helps guard against sample cross-contamination and is convenient for colour-coding to particular R&D projects. Hexa-Flex Safety Caps protect your laboratory staff from highly-infectious organisms such as TB and the HTLV-III virus.
