Polypropylene Centrifuge Tubes 15mL - Sterile Conical Bottom with Screw Cap, Translucent

Premium Laboratory Centrifuge Tubes - Professional Grade for Accurate Sample Processing

Elevate your laboratory workflow with these high-performance 15 mL centrifuge tubes, expertly engineered for demanding research, clinical diagnostics, and laboratory applications. Manufactured from premium-grade polypropylene with precision-molded conical bottoms, these tubes deliver exceptional durability, clarity, and reliability for all your centrifugation needs.

Superior Construction & Materials

High-Quality Polypropylene Construction: Each tube is precision-molded from medical-grade polypropylene, a material renowned for its exceptional chemical resistance, durability, and clarity. The translucent design allows for easy visual inspection of samples without opening the tube, reducing contamination risk while enabling quick sample assessment. This robust material withstands repeated use and maintains structural integrity even under rigorous laboratory conditions.

Engineered Conical Bottom Design: The precisely molded conical bottom maximizes sample recovery and facilitates complete pellet formation during centrifugation. This thoughtful design ensures minimal sample loss and makes resuspension easier, critical for applications requiring maximum yield. The smooth interior surface prevents sample adhesion and simplifies cleaning for reuse.

High-Performance Centrifugation Capabilities

Exceptional RCF Rating: With an impressive 8,078xG RCF rating and 8,500 RCF spin rate capacity, these tubes are built to handle high-speed centrifugation applications with confidence. Whether you're performing cell pelleting, protein precipitation, nucleic acid extraction, or other separation techniques, these tubes deliver consistent, reliable performance across a wide range of protocols and applications.

Leak-Resistant Screw Cap System: Each tube comes equipped with a blue, flat-top screw cap manufactured from high-density polyethylene (HDPE). The precision-threaded design creates a secure, leak-resistant seal that protects your valuable samples during centrifugation, storage, and transport. The flat-top design allows for stable stacking and efficient use of limited laboratory space.

Precision Measurement & Labeling Features

Accurate Graduated Markings: Black printed graduations in precise 0.5 mL increments run along the length of each tube, enabling accurate volume measurements without additional equipment. The high-contrast black markings remain clearly visible against the translucent tube material, ensuring reliable readings even with colored or turbid samples.

Large White Writing Space: A generous white frosted writing area provides ample room for detailed sample identification using standard laboratory markers. This convenient labeling space accepts permanent markers, pencils, and labels, ensuring your samples remain properly identified throughout processing, storage, and analysis. Clear labeling reduces errors and improves laboratory workflow efficiency.

Sterility & Reusability

Sterile & Ready to Use: Each tube arrives sterile and ready for immediate use in critical applications, eliminating time-consuming pre-treatment steps. The sterile packaging protects sample integrity and prevents contamination in sensitive molecular biology, cell culture, and clinical diagnostic procedures.

Autoclavable for Extended Use: These tubes are fully autoclavable (without caps) at standard sterilization temperatures, making them ideal for laboratories seeking cost-effective, reusable solutions. The durable polypropylene construction withstands repeated autoclaving cycles without warping, cracking, or losing clarity, providing excellent long-term value.

Convenient Organization & Storage

Racked with Color-Coded Caps: Tubes arrive conveniently organized in racks with color-coded blue screw caps already attached, streamlining laboratory organization and sample management. The rack system facilitates efficient storage, reduces handling time, and minimizes the risk of sample mix-ups. Color-coding enables quick visual identification and sorting of different sample types or experimental groups.

Safety & Compatibility

Latex-Free Construction: Manufactured without natural rubber latex, these tubes are safe for use in all laboratory environments, including those serving latex-sensitive individuals. This feature is particularly important in clinical settings and research facilities with strict allergen protocols.
