Invitrogen Centrifuge Tube 2 ml with Snap-Caps Pack of 500 Tubes

Invitrogen 2 ml Microcentrifuge Tubes (AM12425)

The Invitrogen AM12425 is a premium 2 ml microcentrifuge tube engineered for high-integrity sample preparation and long-term storage in molecular biology workflows. Manufactured from high-clarity, medical-grade virgin polypropylene, these tubes feature a robust "snap-cap" design that provides a secure, liquid-tight seal during high-speed centrifugation and thermal cycling. The 2 ml volume provides critical additional capacity for protocols involving high-volume elution, nucleic acid precipitation, and master mix preparation. Certified to be free of DNase, RNase, and protease contamination, the AM12425 is specifically validated for use with sensitive Invitrogen and Applied Biosystems genomic workflows, ensuring that your precious samples remain protected from enzymatic degradation.

Technical Performance and Design

• Enhanced 2 ml Capacity: Provides extra volume compared to standard 1.5 ml tubes, making it ideal for procedures that require large amounts of lysis buffer or multiple wash steps.

• Exceptional Clarity: The ultra-clear polypropylene resin allows for effortless visual monitoring of sample pellets, liquid interfaces, and colorimetric changes.

• High-Force Centrifugation: Engineered with reinforced walls to withstand high RCF (Relative Centrifugal Force) ratings typically required for genomic DNA and RNA pelleting.

• Frosted Writing Surface: Features a large, frosted side-wall area and a frosted flat cap, providing a reliable surface for permanent marking and easy sample identification.

Key Benefits & Applications

• Nucleic Acid Purification: The designated tube for many Invitrogen RNA and DNA isolation kits where total volume exceeds 1.5 ml during the lysis or neutralization phases.

• Protein Sample Prep: Ideal for protein assays and immunoprecipitation (IP) where sample volume and low-binding surface properties are critical for recovery.

• Cryogenic Storage: Suitable for sample storage in vapor-phase liquid nitrogen or ultra-low temperature freezers (-80°C).

• Master Mix Preparation: The larger volume is perfect for mixing concentrated PCR master mixes or enzyme cocktails for high-throughput experiments.
