G-Tubes™ - Microcentrifuge Tubes with MaxSeal™ SnapCaps

G-Tube Microcentrifuge Tubes are designed with MaxSeal™ SnapCaps for secure closure and to withstand high temperatures and pressure. SnapCaps are flat, larger, and etched for an enhanced writing surface. The G-Tube's superior design allows this tube to rated to 30,000 x G. It is virtually transparent and far exceeds the toughness of any other microcentrifuge tube. When the G-Tube's snapcap is closed there will be an audible "snap" that indicates a secure closure has been formed. SnapCaps feature a target syringe port, easily pierced, for splash free handling.
