CLEARLine® Microcentrifuge Tubes, Screw Cap with O-ring, Sterile

CLEARLine® microcentrifuge tubes with screw cap are manufactured from high-quality medical grade raw materials, ensuring reliability, safety and consistent performance in laboratory applications. The combination of a polypropylene tube and a polyethylene cap allow smooth opening and closing, avoiding the typical grip effect providing secure, leak-proof sample storage. They are ideal for high-speed centrifugation and sensitive workflows.

The tubes withstand centrifugation up to 25,000 x g and operate within a range from -85°C to +121°C. They are autoclavable at 121°C for 20 minutes, ensuring compatibility with standard sterilization procedures.

All raw materials comply with USP Class VI and ISO 10993 standards, ensuring biocompatibility. The tubes are non-cytotoxic, non-hemolytic, free from heavy metals and do not contain animal-derived components.

Designed for practicality and ease of use, the tubes feature an engraved writing area and clear graduations for accurate sample identification. They are available in multiple configurations, including conical bottom and self-standing formats (0.5, 1.5 and 2 ml), with different cap styles and color options for efficient sample management.

CLEARLine® sterile microcentrifuge tubes are sterilized using a validated process ensuring a SAL of 10⁻⁶. They are certified DNase, RNase and endotoxin free, making them suitable for molecular biology, DNA/RNA applications and other sensitive laboratory procedures.
