Eppendorf Centrifuge Tube 0.5 ml with Snap Cap 1000 Tubes

Eppendorf 22363611 Safe-Lock Centrifuge Tubes – 0.5 ml (Clear)

The Eppendorf 22363611 is a premium 0.5 ml microcentrifuge tube engineered for maximum sample safety and reliability. Featuring the world-renowned Safe-Lock lid, these tubes provide an extra level of protection with an integrated hinged "hook" that locks the cap securely in place. This design prevents accidental lid opening during centrifugation, incubation, or thermal stress, ensuring sample integrity for high-precision molecular biology and clinical research. Manufactured from high-purity polypropylene, these tubes offer exceptional chemical resistance and high mechanical stability for demanding laboratory workflows.

Technical Performance and Design

• Patented Safe-Lock Lid: The integrated lid hook ensures the tube remains securely closed even when heating samples to 100°C or centrifuging at maximum speeds, providing peace of mind during critical experiments.

• High Centrifugation Stability: Rated to withstand up to 30,000 x g, these tubes allow for rapid pelleting of DNA, proteins, and cellular debris without the risk of tube failure or leakage.

• Exceptional Material Purity: Fabricated from virgin polypropylene without the use of slip agents, plasticizers, or biocides, ensuring that your samples remain free from leachable contaminants that could interfere with PCR or spectrophotometric readings.

• Large Labeling Surface: Features a frosted lid and a frosted side area for secure sample identification, alongside clear volume graduations for quick visual checks.

Key Benefits & Applications

• Molecular Biology: Ideal for PCR template preparation, enzymatic reactions, and genomic sample storage where evaporation or accidental cap opening must be avoided.

• Safe Sample Incubation: The locking lid is particularly beneficial when boiling samples or using dry bath heaters, as it prevents the internal pressure from popping the cap open.

• Space-Saving Storage: The 0.5 ml micro-format allows for high-density storage in freezer boxes, optimizing space in -20°C and -80°C cryo-storage environments.

• Precise Fluid Handling: The smooth interior surface and precise molding allow for the total recovery of low-volume samples, critical when working with expensive enzymes or rare biological materials.
