Fisherbrand Micro Centrifuge Tubes Sterile Individually Wrapped 2 ml Locking Lid - Lot of 500 Tubes

Fisherbrand 2 ml Sterile Micro Centrifuge Tubes with Locking Lids (Lot of 500)

Engineered for rigorous molecular biology and clinical diagnostic workflows, the Fisherbrand 2 ml micro centrifuge tubes provide reliable sample security and integrity. Manufactured from high-clarity, ultra-pure virgin polypropylene, these tubes offer exceptional chemical resistance and structural stability under high-speed centrifugation. Each tube is sterilized and individually wrapped, ensuring absolute protection against cross-contamination and environmental particulates prior to use. The innovative locking lid mechanism securely snaps shut, preventing accidental opening, sample evaporation, and biohazardous aerosolization during critical heating or boiling steps. With a highly transparent wall design and molded graduations, laboratory personnel can quickly and accurately assess sample volumes. These features make them an indispensable consumable for specialized applications ranging from nucleic acid extraction to rigorous thermal cycling.

Technical Performance and Design

• Locking Lid Mechanism: Secures samples during thermal cycling, boiling, and prolonged storage, significantly reducing the risk of lid pop-ups and preventing sample loss or evaporation.

• Individual Sterile Wrapping: Guarantees the asepsis of each single tube until the precise moment of use, which is critical for highly sensitive, contaminant-free clinical and genomic environments.

• Premium Polypropylene Construction: Delivers excellent optical clarity for visual sample inspections and withstands extreme centrifugal forces, corrosive chemical solvents, and broad temperature fluctuations.

• Tactile Frosted Marking Areas: Provides an optimized, textured surface on both the cap and side wall for permanent marker labeling, ensuring durable and legible sample identification.
