A centrifuge tube is a specialized laboratory vessel designed to hold liquid samples during centrifugation procedures. Made of durable materials like polypropylene or borosilicate glass, it withstands high rotational speeds and mechanical stress without deformation. Available in various volumes from 0.5mL to 50mL, it features clear scale markings for precise sample measurement. Many versions are autoclavable and chemically resistant, suitable for applications in cell separation, protein purification, and clinical diagnostics.

Crafted from premium polypropylene, our centrifuge tubes withstand a maximum centrifugal force of 15,000×g without cracking or deformation, fully compliant with ISO 10993 standards. The reinforced tube body and seamless design eliminate the risk of sample leakage during high-speed operations, making them ideal for intensive separation tasks like cell pellet collection and nucleic acid purification.
We offer two reliable material choices: autoclavable polypropylene and heat-resistant borosilicate glass. Plastic tubes undergo gamma irradiation sterilization (SAL 10⁻⁶) and come ready-to-use, avoiding cross-contamination. Glass tubes can be autoclaved repeatedly at 121℃ for 20 minutes. Both materials feature clear, fade-proof scales for accurate sample volume reading at a glance.
SealingEquipped with a screw-cap closure and a silicone O-ring gasket, our centrifuge tubes achieve 100% leak-proof performance even when inverted or shaken vigorously. The cap’s ergonomic ribbed design ensures easy tightening and loosening, even with gloved hands. This design prevents sample evaporation and contamination, preserving the integrity of valuable biological samples during storage and centrifugation.
Our centrifuge tubes exhibit strong resistance to most acids, bases, organic solvents, and detergents, with no material degradation or sample adsorption. This compatibility allows their use in a wide range of lab workflows, including protein precipitation, DNA extraction, and metabolite analysis. The smooth inner wall minimizes sample retention, maximizing recovery rates for trace samples.
Centrifuge tubes are widely used in environmental labs to process water, soil, and sewage samples. They separate suspended solids, sediments, or microbial colonies from liquid matrices via centrifugation, providing purified supernatants for subsequent heavy metal detection, pollutant quantification, and ecological risk assessment.
These tubes help isolate target substances from food homogenates. They separate bacteria, mold, or pesticide residues from liquid extracts, enabling accurate detection of foodborne pathogens and contaminants. Their sterile design prevents external pollution, ensuring reliable test results for quality control.
Centrifuge tubes handle animal blood, urine, and tissue homogenate samples. They separate serum, plasma, or cell pellets efficiently, supporting the detection of animal diseases, hormone level measurement, and vaccine efficacy evaluation. Their chemical resistance suits diverse veterinary testing reagents.
Industrial biotech, centrifuge tubes are applied in pilot-scale fermentation sample processing. They separate microbial cells from fermentation broths, facilitating the extraction of bioactive substances like enzymes, antibiotics, and probiotics. Their high-speed resistance meets the demands of rapid production quality monitoring.
1.Add samples to the centrifuge tube, filling no more than 2/3 of its volume to prevent leakage during centrifugation.
2.Match tubes with equal weight for balanced placement in the centrifuge rotor.
3.After centrifugation, wait for the rotor to stop completely before opening the lid and taking out the tubes.
4.Seal unused tubes tightly for storage in a clean, dry place.
