Optimal Sample Security and PreservationThese cryo tubes provide secure storage for biological samples, facilitated by their silicone O-ring screw cap. The external threading and precise sealing prevent leaks, maintaining sample integrity throughout storage and transport. Pre-sterilization and RNase/DNase-free construction further ensure sample purity for sensitive applications.
Versatile Temperature Resistance and ApplicationWith a broad temperature range from -196C to +121C, these tubes are suitable for both cryogenic freezing and autoclave sterilization. They accommodate a variety of samples, including fluids, tissues, and cells, making them essential for laboratories, biobanks, and molecular biology research environments.
User-Friendly Design with Reliable DurabilityConstructed from high-quality polypropylene, the tubes are lightweight, non-breakable, and easy to handle manually. The transparent body and clear graduation marks enable precise measurement and straightforward labeling, streamlining workflow in high-throughput laboratory settings.
FAQs of Externally Threaded 5.0ml Polypropylene Cryo Tubes:
Q: How do the external thread and silicone O-ring cap ensure a leak-proof seal in these cryo tubes?
A: The screw cap features an external thread design combined with a durable silicone O-ring that compresses tightly against the tube rim, providing a secure, leak-proof barrier and reducing the potential for contamination or sample loss during storage and transport.
Q: What types of biological samples can be stored in these polypropylene cryo tubes?
A: These tubes are compatible with a wide range of biological materials, including fluids, cells, and tissues, making them highly suitable for laboratory sample storage, biobanking, and molecular biology applications.
Q: When should these cryo tubes be used in the sample management process?
A: The tubes should be employed when long-term cryogenic or short-term cold storage of sensitive biological samples is required, particularly when sterile, RNase/DNase-free conditions and reliable containment are essential.
Q: Where are these externally threaded cryo tubes typically utilized?
A: They are widely used in biotechnology, clinical, academic, and research laboratories throughout India and internationally, serving exporters, importers, manufacturers, suppliers, and traders in life science and healthcare sectors.
Q: What is the process for labeling and measuring samples inside the cryo tube?
A: Graduation marks up to 5.0 ml are printed on the tube alongside a designated marking area, enabling users to directly record sample information and accurately measure volume without the need for additional tools.
Q: How does the tube material contribute to its performance and safety?
A: The polypropylene construction offers chemical resistance, high durability, and non-reactivity, while being autoclavable and capable of withstanding extreme temperatures, ensuring both performance in laboratory procedures and safe long-term storage.
Q: What are the benefits of choosing this particular cryo tube model for sample storage?
A: This model provides reliable, contamination-free sample preservation, easy handling due to its lightweight design, and exceptional versatility across a wide temperature range. Its sterility and high-grade materials ensure suitability for demanding scientific work.
