Reliable Sterility & Sample ProtectionEach tube undergoes gamma irradiation to guarantee sterility, eliminating RNase, DNase, and pyrogen contamination. This ensures the safety and purity of sensitive biological samples, vital for molecular biology and diagnostic applications. With a leak-proof screw cap and strong polypropylene construction, the tube maintains its integrity during centrifugation and storage.
User-Friendly Design FeaturesThe 50 mL tube is transparent for easy sample inspection and features clear graduation markings in 2.5 mL increments for precise measurement. Its durable polypropylene material allows it to tolerate temperatures from -80C (freezing) up to 121C (autoclaving) without deformation, making it suitable for a broad range of laboratory processes.
Versatile Packaging & CompatibilityAvailable individually wrapped or in convenient packs of 25, 50, or 100, these tubes fit standard laboratory microcentrifuges. Their conical, flat-bottom design and high chemical resistance make them indispensable tools for sample separation, mixing, and storage in research, clinical, and educational settings.
FAQs of 50 ML MICROCENTRIFUGE TUBE STERILE:
Q: How do I use the 50 mL microcentrifuge tube for sample separation in my laboratory?
A: Simply load your sample into the tube and secure the leak-proof screw cap. Place the tube in a compatible microcentrifuge and run up to a maximum RCF of 12,000 x g for effective separation. The conical shape helps collect the pellet at the bottom for easy retrieval and analysis.
Q: What benefits does the clear, graduated design provide during sample handling?
A: The transparent tube enables visual monitoring of your samples, while the printed graduations in 2.5 mL increments allow for accurate measurement and aliquoting. This facilitates precise sample preparation, mixing, and reproducibility in experiments.
Q: When should I choose this sterile microcentrifuge tube over non-sterile alternatives?
A: Opt for the sterile version whenever handling sensitive samples in molecular biology, biochemistry, or clinical diagnostics to avoid contamination with RNase, DNase, or pyrogens. Sterile tubes are also essential for applications requiring stringent sample integrity and purity.
Q: Where should I store these tubes to maintain their sterility and quality?
A: Store the tubes in a clean, dry environment away from direct sunlight and heat. This preserves their sterility and physical integrity, ensuring a shelf life of up to five years under proper conditions.
Q: What is the maximum temperature resistance and how does it benefit laboratory processes?
A: These tubes withstand temperatures from -80C up to 121C, allowing them to be safely used for freezing samples or autoclaving for sterilization. This versatility supports a wide range of laboratory workflows and sample handling needs.
Q: Are these tubes suitable for all standard laboratory microcentrifuges and what is the closure type?
A: Yes, the tubes are compatible with standard microcentrifuges. The closure type is a screw cap, designed for leak-proof performance and rapid, secure sealing during mixing, centrifugation, or transport.
