Product Introduction
- Product Overview: The Centrifuge Tube developed by Xiamen Zhizi Industry & Trade Co., Ltd. is a professional laboratory consumable designed for sample separation, purification, and storage in scientific research, clinical testing, and biopharmaceutical fields. Covering 7 common capacities (0.5mL, 1.5mL, 2mL, 10mL, 15mL, 50mL, 100mL), this Centrifuge Tube replaces traditional low-performance centrifugal containers, solving pain points such as tube rupture under high speed and sample adsorption. Each Centrifuge Tube integrates high-pressure resistance, leak-proof sealing, and easy operation, providing a reliable solution for processes like plasmid extraction, blood component separation, and cell supernatant collection. With its excellent compatibility and stability, it has become a preferred choice for laboratories to optimize sample processing workflows.
- Product Performance: The Centrifuge Tube excels in centrifugal resistance, sample protection, and compatibility. Made of medical-grade PP or PC material, it tolerates 15,000rpm (PP) to 25,000rpm (PC) high-speed centrifugation without deformation. The dual-seal structure (screw cap + silicone gasket) prevents aerosol leakage, while the plasma-polished inner wall (Ra≤0.2μm) reduces protein adsorption to <0.1μg/cm². Laser-etched scales (accuracy ±2%) support precise sample measurement. It is compatible with mainstream centrifuges (Eppendorf 5424R, Thermo Fisher Sorvall ST16) and automated liquid handling systems, and can withstand -80℃ freezing to 121℃ autoclaving (PP), meeting diverse experimental needs.
2. Product Advantages
- High-Pressure Material & Precision Molding for High-Speed Centrifugation: The Centrifuge Tube is made of medical-grade high-purity PP or PC material, manufactured via "bidirectional stretch injection molding". This process ensures uniform tube wall thickness (error ≤0.1mm), enabling the PP-version Centrifuge Tube to tolerate 15,000rpm high-speed centrifugation and the PC-version to withstand 25,000rpm ultra-high-speed centrifugation—no deformation or rupture occurs even under extreme centrifugal force. The tube bottom adopts an "arc gradient design" to reduce stress concentration caused by liquid vortex during centrifugation, and the reinforced rib structure on the tube body maintains integrity at 12,000rpm (RCF≥18,000×g). This prevents sample loss and contamination from tube breakage, making it ideal for high-frequency centrifugation scenarios like molecular biology (plasmid extraction) and clinical testing (blood component separation).
- Dual Sealing & Low-Adsorption Inner Wall to Ensure Sample Purity: The Centrifuge Tube features a "dual sample protection system". First, the tube cap uses a "screw + silicone gasket" dual-seal structure—the silicone gasket is precision die-cut (thickness error ≤0.05mm) with 99% fitting degree to the tube mouth, preventing aerosol leakage or external contamination during centrifugation, which is essential for pathogen sample processing in biosafety level 2+ laboratories. Second, the inner wall undergoes "plasma polishing", resulting in a surface roughness of Ra≤0.2μm. This reduces protein adsorption to <0.1μg/cm² and nucleic acid adsorption to <0.05ng/cm², minimizing sample loss (e.g., enzymes, antibodies, rare nucleic acids) from wall adsorption. Experimental verification shows that sample recovery rate is 12% higher than ordinary centrifuge tubes, ensuring accurate results for subsequent tests (Western Blot, qPCR).
- Clear Scales & Humanized Design to Improve Operation Efficiency: The Centrifuge Tube optimizes details for laboratory habits. It uses "laser-etched scales" with a line width of only 0.1mm and accuracy of ±2% (e.g., 10mL tube has 1mL scale error ≤0.02mL), supporting precise sample/reagent measurement. Laser scales resist alcohol wiping and won’t fade with long-term use. The tube cap top has "anti-slip patterns" and "identification grooves"—anti-slip patterns increase friction for easy twisting even with gloves, and identification grooves accept handwritten labels or laser coding for sample classification. Additionally, 15mL/50mL Centrifuge Tubes have "skirted bases" (15% wider than the tube body) for stable placement and compatibility with universal tube racks (15mL fits 16mm holes, 50mL fits 22mm holes), eliminating the need for extra consumables.
- Full-Spec Coverage & Wide Compatibility for Diverse Scenarios: The Centrifuge Tube offers a "full-spec product matrix" with 7 capacities (0.5mL-100mL) to meet different needs—0.5mL for micro RNA extraction, 50mL for cell culture supernatant centrifugation. Materials include "standard PP" (tolerates -80℃ freezing to 121℃ autoclaving for 15min) and "high-temperature PC" (resists 135℃ short-term heating), 适配 sample freezing and reusable sterilization. All Centrifuge Tubes comply with ISO 10452, directly compatible with mainstream centrifuge rotors (Eppendorf 5424R, Thermo Fisher Sorvall ST16) without rotor parameter adjustment. They also fit the tip height of automated liquid handling systems (Tecan Freedom EVO), reducing manual intervention and improving high-throughput sample processing efficiency.
3. Product Application Scenarios
- Molecular Biology Labs: In molecular biology labs, the Centrifuge Tube is widely used for plasmid extraction, RNA/DNA purification. Researchers use 1.5mL/2mL Centrifuge Tube to centrifuge bacterial lysates, and the low-adsorption inner wall ensures high nucleic acid recovery. The Centrifuge Tube’s high-speed resistance (15,000rpm) meets the needs of nucleic acid precipitation centrifugation. Every experiment relies on the Centrifuge Tube for sample separation, and the Centrifuge Tube’s precision scales help control reagent addition. Without the Centrifuge Tube, molecular biology experiments would face low sample yield and high contamination risks.
- Clinical Testing Labs: In clinical testing labs, the Centrifuge Tube is essential for blood component separation and urine sediment testing. For blood tests, 10mL/15mL Centrifuge Tube separates serum/plasma from blood cells at 3,000rpm, and the dual-seal structure prevents cross-infection. For urine tests, 50mL Centrifuge Tube collects urine samples for sediment centrifugation. The Centrifuge Tube’s compatibility with automated analyzers speeds up testing. Every day, labs use hundreds of Centrifuge Tube, and the Centrifuge Tube ensures accurate and timely test results for patient diagnosis.
- Biopharmaceutical Production: In biopharmaceutical production, the Centrifuge Tube is used for cell culture supernatant clarification and protein purification. 50mL/100mL Centrifuge Tube centrifuge cell suspensions at 8,000rpm to remove cell debris, and the high-transparency material allows observation of sediment. The Centrifuge Tube’s sterilizable feature (121℃ autoclaving) meets GMP requirements. Every production batch uses thousands of Centrifuge Tube, and the Centrifuge Tube’s stability guarantees consistent product quality. The Centrifuge Tube is a key consumable for biopharmaceutical manufacturing.
4. Frequently Asked Questions
- Q: Can the PP-version Centrifuge Tube be reused after autoclaving?
A: Yes, the PP-version Centrifuge Tube can be autoclaved at 121℃ for 15min and reused 3-5 times. However, it’s recommended to check for wall cracks or seal aging after each autoclaving—discard if damaged to avoid sample leakage.
- Q: What is the maximum RCF (relative centrifugal force) the Centrifuge Tube can withstand?
A: The PP-version Centrifuge Tube tolerates a maximum RCF of 18,000×g (15,000rpm for 10mL tube), while the PC-version can withstand up to 30,000×g (25,000rpm for 10mL tube). Refer to the product manual for specific RCF values of different capacities.
- Q: Is the Centrifuge Tube compatible with organic solvents (e.g., ethanol, DMSO)?
A: The PP-version Centrifuge Tube is compatible with most low-concentration organic solvents (ethanol ≤70%, DMSO ≤10%), but avoid strong acids/bases. The PC-version has better solvent resistance but is not compatible with chloroform. Test compatibility with specific solvents before use.
