Fisherbrand Microcentrifuge Tube 1.5 mL Snap-Cap 500 tubes

Fisherbrand 02-681-5 Microcentrifuge Tubes – 1.5 mL, Snap-Cap, Graduated

The Fisherbrand 02-681-5 is a premium 1.5 mL disposable microcentrifuge tube designed to be the ultimate daily workhorse for molecular biology, biochemistry, and clinical laboratories. Manufactured from high-purity, chemical-resistant virgin polypropylene, these tubes feature a securely sealing flat-top snap cap that actively resists popping open during vigorous vortexing, thermal incubation, or boiling. Equipped with high-visibility molded graduations for quick volume estimation and an ultra-smooth interior to maximize sample recovery, the 02-681-5 is an indispensable, highly reliable consumable for nucleic acid extraction, protein purification, and everyday laboratory aliquoting.

Technical Performance and Design

• Secure Snap-Cap Seal: The flat-top attached lid is precisely engineered to provide a tight, leak-proof friction fit. It closes with a definitive tactile "click," ensuring samples remain secure during high-temperature incubations without the lid unexpectedly popping open.

• High Centrifugal Stability: Built with a reinforced wall construction that effortlessly withstands extreme centrifugal forces (frequently up to 26,000 x g), making it perfect for hard-pelleting cellular debris or precipitating DNA without the tube shattering in the rotor.

• Premium Polypropylene: Molded from highly durable, virgin polypropylene that offers excellent chemical resistance to standard laboratory reagents, including phenol-chloroform mixtures, guanidine thiocyanate, and alcohols.

• Certified Pure: Manufactured under stringent quality controls and certified to be strictly RNase-free and DNase-free, guaranteeing the absolute integrity of your most sensitive genomic and transcriptomic samples.

Key Benefits & Applications

• Nucleic Acid & Protein Prep: The ultra-smooth interior surface minimizes non-specific binding, ensuring maximal recovery of low-concentration DNA, RNA, and delicate protein pellets after centrifugation.

• Thermal Versatility: Fully autoclavable at 121°C for sterile workflows, and robust enough to endure long-term cryogenic storage down to -80°C without the plastic turning brittle and cracking.

• Easy Sample Identification: The flat cap and the frosted side panel provide an excellent, smudge-resistant surface for writing with laboratory markers or applying tiny printed barcode labels.

• Ergonomic Handling: The flexible hinge allows the tube to be easily opened and closed with one hand, drastically reducing thumb fatigue for technicians processing hundreds of samples a day.
