Ambion Microfuge Tube 0.5 ml Non-Stick Box of 500 Tubes

Ambion® Non-Stick 0.5 mL Polypropylene Microfuge Tubes (AM12350) – Box of 500

The Ambion® AM12350 (now supported under the Invitrogen brand by Thermo Fisher Scientific) is an ultra-low retention microcentrifuge tube engineered for quantitative biochemical assays, genomic mapping, and rare sample bio-banking. Utilizing a proprietary co-polymer formulation, these 0.5 mL tubes create a naturally slick, hydrophobic non-stick inner surface without utilizing hazardous chemical coatings or silicone additives. Supplied in a box of 500 tubes, this validation-ready architecture guarantees maximal recovery of precious nucleic acids, enzymes, and proteins while satisfying strict RNase- and DNase-free baseline specifications.

Technical Performance & Design

• Co-Polymer Non-Stick Boundary: Fabricated from a specialized polypropylene blend that physically prevents the irreversible adsorption of hydrophobic molecules, ensuring total sample ejection and zero stick-down variables.
• Secure Snap-Cap Closure: Outfitted with an ergonomically optimized flat snap-cap that snaps firmly into an internal sealing rim, creating a liquid-tight mechanical compression seal capable of withstanding extreme thermal expansions.
• High Centrifugal Force Rating: Mechanically cross-linked to handle high-velocity deceleration vectors up to 20,000 x g inside standard microcentrifuge angle rotors without micro-cracking or stress fracturing.
• Certified Molecular Biology Purity: Subjected to strict lot-specific quality controls to certify that the components are completely free from detectable RNase, DNase, human DNA, and PCR inhibitors.

Key Benefits & Applications

• Low-Concentration Protein & Nucleic Acid Elution: Highly recommended for single-cell genomics, next-generation sequencing library preparation, and high-precision qPCR setups where any wall adherence could cause catastrophic concentration drift.
• Radio-Labeled Tracer Storage: Restricts the binding of complex isotopic reagents or hydrophobic fluorescent tags to the container walls, maximizing detectable emissions.
• Ergonomic Workstation Handling: The frosted cap surface provides an ideal texture for manual marking, while the smooth closure dynamics prevent thumb fatigue across continuous liquid manipulation series.
• Optical Visual Inspection: The premium clarity of the side-wall polymer enables simple visual checks of micro-volume pellets, fluid levels, and interface separations.
