Product Description
15ml Centrifuge Tubes
Placed in centrifuges, these glass or plastictubes can hold samples while rotating at very high velocity without spillingthem. Also known as centrifuge vials, you can use them to segregate solids fromliquid biochemical solutions. They look a lot like mini test tubes owing totheir tapered bottom.
We offer free-standing and conical centrifuge tubes in 15ml and 50mlsizes. Our centrifuge tubes have more cavities compared to other similarproducts.
Designed for Reliable Laboratory PerformanceThese 15ml conical centrifuge tubes provide precision and reliability for researchers and lab technicians. Resistant to chemicals and temperature extremes, they ensure sample integrity during demanding procedures, including centrifugation and autoclaving. The leak-proof design and molded graduations streamline workflow.
Versatile Tubes for Diverse ApplicationsUsed across microbiology, molecular biology, and general lab processing, these tubes accommodate sample centrifugation, mixing, and long-term storage. The sterile and non-sterile choices allow flexibility for a range of experimental protocols, promoting lab safety and efficiency.
Features Supporting Sample Identification and HandlingWith a white printed marking spot and easy-to-read graduation markings in 0.5 ml increments, sample identification and quantification are simplified. The tubes high clarity and cap color options (orange or blue) assist in organizing and handling tasks in shared laboratory settings.
FAQs of 15ml Centrifuge Tubes:
Q: How should 15ml centrifuge tubes be stored to maximize shelf life?
A: For optimal shelf life of up to 5 years, keep the tubes in a cool, dry place, away from direct sunlight and harsh chemicals. Sterile tubes should remain in unopened packaging until use to preserve sterility.
Q: What are the benefits of the screw cap design on these tubes?
A: The screw cap ensures a secure, leak-proof closure, preventing sample loss during centrifugation or storage. Both flat and plug seal cap options provide reliable containment and easy handling, reducing the risk of contamination.
Q: When is it recommended to use a sterile versus non-sterile tube?
A: Sterile tubes are preferred for sensitive procedures like molecular biology or microbiology to avoid contamination. Non-sterile versions are suitable for routine tasks where sterility is not critical, such as sample mixing or storage.
Q: Where are these 15ml centrifuge tubes commonly used?
A: They are widely used in laboratories across the fields of microbiology, molecular biology, clinical diagnostics, and educational research for tasks involving sample centrifugation, preparation, and storage.
Q: What is the process for autoclaving these polypropylene tubes?
A: To autoclave, place tubes in a suitable rack and ensure caps are loosely attached to prevent pressure buildup. Polypropylene tubes withstand temperatures up to 121C, enabling repeated sterilization without compromising structure.
Q: How does the molded graduation scale aid in sample measurement?
A: The molded scale, marked in 0.5 ml increments (+/- 2% accuracy), allows for precise sample volume measurement, streamlining experimental setup and reducing errors during liquid handling procedures.
Q: What are the key advantages of using high-clarity polypropylene tubes?
A: High-clarity polypropylene enables easy visual inspection of samples, facilitates accurate volume assessment, and ensures durability against chemicals and extreme temperatures, making the tubes suitable for rigorous lab routines.
