These conical-bottom centrifuge tubes are engineered for precise sample handling in laboratory environments. Constructed from robust polypropylene or high-density polyethylene, they withstand high-speed centrifugation and diverse chemical exposures. Transparent tube bodies with clear graduation marks simplify volume assessment, while secure screw cap closures minimize contamination risk.
Available as certified sterile, RNase/DNase-free, and pyrogen-free, these tubes are suited for sensitive biological applications. Their autoclavable design ensures safe reuse, supporting rigorous lab workflows while maintaining sample integrity and reliability.
FAQ's of Centrifuge Tube Conical Bottom, PP/HDPE:
Q: How are the graduation marks applied on Centrifuge Tube Conical Bottom, and what is their benefit?
A: The graduation marks are either printed or molded directly onto the transparent tube for clear, accurate volume measurements. This feature ensures precise sample quantification and easy visual verification during laboratory procedures.
Q: What materials are used in the construction of these centrifuge tubes and caps?
A: Tube bodies are manufactured from polypropylene (PP) or high-density polyethylene (HDPE), providing excellent chemical resistance and durability. The screw caps are typically made from HDPE or PE, designed to form tight, leak-proof seals during use.
Q: When should I use sterile, RNase/DNase-free, or pyrogen-free centrifuge tubes?
A: Sterile, RNase/DNase-free, and pyrogen-free tubes are essential when handling sensitive biological samples, such as RNA, DNA, or clinical specimens, to prevent contamination and ensure reliable results.
Q: Where are conical bottom centrifuge tubes predominantly used?
A: These tubes are widely utilized in laboratories across research, clinical, and industrial settings in India and internationally, primarily for centrifugation, sample storage, and separation applications.
Q: What is the recommended temperature and speed tolerance for these tubes?
A: Centrifuge Tube Conical Bottom can withstand temperature ranges from -80C to 121C and are autoclavable at 121C. They are suitable for centrifugation speeds up to 12,000 x g, subject to manufacturer guidelines.
Q: What pack sizes are available, and how does this benefit laboratory workflow?
A: The tubes are commonly supplied in racks of 25, 50, or 100 units, facilitating organized storage, easy access during experiments, and efficient inventory management in busy laboratory settings.
Q: How do I ensure leak prevention and secure closure during centrifugation?
A: Each tube is equipped with a screw cap featuring precise threading and robust materials, ensuring a tight, leak-proof seal even during high-speed centrifugation or temperature fluctuations, thus safeguarding sample integrity.
