Frequently asked questions
Are these tubes durable for high-speed centrifugation?
Yes, these microcentrifuge tubes are engineered for high-performance durability and are rated to withstand up to 20,000 RCF, ensuring they are compatible with most standard and high-capacity laboratory rotors.
Can these handle extreme temperature fluctuations?
Absolutely. The robust polypropylene construction allows these tubes to maintain integrity across a wide temperature range, specifically from -80°C to 121°C (-112°F to 250°F), making them suitable for both deep-freezing and autoclaving.
Do these tubes ensure sample purity?
Yes, these are manufactured to high food-grade standards and are certified to be free from:
- DNase
- RNase
- Pyrogens
- DNA
This ensures your samples remain uncontaminated throughout your procedures.
Is the cap design effective for preventing leaks?
The tubes feature a permanently attached, secure snap-cap that is specifically designed to minimize spill risks. The cap also incorporates a specialized thin membrane, allowing for convenient needle access without needing to open the lid, which further protects against cross-contamination.
How clear is the plastic for optical analysis?
The tubes are made from high-clarity, naturally colored polypropylene. This provides an unobstructed view of your sample, making them perfectly suitable for spectrophotometer readings and other light-based analysis.
Can I easily label these tubes?
Yes, each tube features a built-in frosted surface area, specifically designed to allow for clear and permanent labeling, ensuring efficient record-keeping in busy laboratory environments.
Are the graduation marks precise for measurements?
Yes, the tubes feature high-contrast, black-printed graduations in 0.25 mL increments. These clear markings allow for accurate, quick volume assessments during your workflow.
Is the material safe for sensitive biological work?
Beyond being certified free of contaminants like DNA and RNase, the tubes are not made with natural rubber latex, making them a safe choice for laboratory professionals with latex sensitivities.
Are these tubes efficient for pellet recovery?
Yes, the tubes are designed with a conical, tapered bottom, which is the optimal shape for concentrating samples and ensuring efficient pellet recovery during centrifugation.
How are these bulk tubes organized for storage?
To maintain laboratory cleanliness and efficiency, the 5,000 tubes are conveniently packaged in 10 separate resealable, tamper-evident, self-standing bags, with 500 tubes per bag.
