Eppendorf Tubes, 1.5ml, 500 Pack

Eppendorf tubes are conical microcentrifuge tubes, essential laboratory consumables for storing, freezing, and transporting biological samples, blood, activators, and derivatives. Their leakproof design makes them ideal for centrifugation, enabling efficient separation of liquids into fractions. A frosted writing area allows for easy, permanent labeling.

Manufactured from high-quality polypropylene, these 1.5ml Eppendorf tubes (pack of 500) offer numerous advantages:

• Secure, One-Handed Lid: The snap-cap lid ensures airtight closure and easy opening with a single hand.
• Leakproof Design: Minimizes the risk of accidental opening, even during heating.
• High Centrifugal Strength: Withstand centrifugation speeds up to 30,000 rpm.
• Exceptional Clarity: High transparency of the polypropylene material allows for easy sample visualization.

Polypropylene Properties & Sterilization

Polypropylene's physical and chemical properties make it ideal for laboratory applications. Optimal use temperature ranges from 0°C to 125°C. Sterilization is possible via autoclaving, chemical treatment (ethanol, formalin), and ethylene oxide (20 minutes at 121°C). These tubes exhibit high resistance to diluted acids, aldehydes, alkalis, and aliphatic hydrocarbons, and demonstrate relatively high chemical resistance to aromatic, halogenated hydrocarbons, ketones, and esters.

Applications

Eppendorf tubes are widely used in medical, clinical, microbiological, and chemical laboratories. Key applications include:

• DNA Extraction: Centrifugation in Eppendorf tubes effectively precipitates concentrated nucleic acid granules from solution (e.g., plasmid DNA extraction at 14,000-15,000 rpm).
• Sample Storage: The secure, snap-cap lid protects samples during experiments, preventing spills and contamination.
• Sample Transportation: The leakproof design makes Eppendorf tubes ideal for safe sample transport.
• PCR Analysis: Frequently used in polymerase chain reaction (PCR) applications.

This 500-pack of 1.5ml Eppendorf tubes provides a cost-effective and reliable solution for various laboratory needs. Their superior quality and performance ensure accurate and consistent results in a variety of applications.
