These 1.5 mL tubes incorporate a high-strength wall and can be centrifuged to twice the g-force that most other microcentrifuge tubes can withstand.

The GateFree™ design and clear polypropylene resin ensure a clear view of the pellet. Tubes also feature flat, pierceable, frosted caps and a side labeling surface. The ergonomically designed caps with smooth surfaces help reduce the potential for repetitive strain injuries. Ideal for phenol/chloroform extractions. Tubes fit all common rotors. Steam autoclavable to 122°C (252°F) and freezable to -90°C (-130°F).
