Frequently asked questions
Are these tubes durable enough for high-speed centrifugation?
Yes, these tubes are engineered for precision performance and are rated for high-speed centrifugation up to 20,000 RCF (xG), ensuring they can withstand demanding laboratory workflows.
Can I use these for long-term storage in freezers?
Absolutely. These tubes are designed 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 cryogenic storage and high-heat sterilization processes.
Will these tubes interfere with my spectrophotometer readings?
No, the tubes are crafted from naturally clear, high-quality polypropylene, which is specifically designed to provide an unobstructed view of sample contents and ensure it does not interfere with spectrophotometer readings.
Are these tubes certified free of contaminants?
Yes, to ensure maximum sample integrity, each tube is guaranteed to be:
- DNase-free
- RNase-free
- Pyrogen-free
- DNA-free
Does the cap provide a secure seal to prevent spills?
The permanently attached snap cap is designed for security and convenience. It includes a thin, needle-pierceable membrane that allows for easy access while minimizing the risk of spills and cross-contamination.
Is the labeling area easy to write on?
Yes, each tube is equipped with a dedicated frosted writing area, allowing for clear and reliable identification of your samples.
Are the graduation marks easy to read?
Yes, the tubes feature large, clearly printed high-contrast black graduations in 0.1 mL increments, allowing for highly accurate measurements during sample preparation.
Are these tubes made with natural rubber latex?
No, these microcentrifuge tubes are strictly latex-free and are constructed from food-grade polypropylene materials.
What is the design of the bottom of the tube?
These tubes feature a conical bottom design. This specific shape is optimized for effective sedimentation and is compatible with both standard and high-capacity centrifuge rotors.
How are the tubes packaged to maintain cleanliness?
The tubes are supplied in tamper-evident, self-standing, and resealable bags, with 500 tubes per bag to ensure they remain clean and organized until you are ready to use them.
