In modern laboratories where accuracy, sterility, and durability are non-negotiable, centrifuge tubes play a foundational role in sample preparation, separation, storage, and transport. We engineer and deliver high-quality centrifuge tubes designed to meet the evolving demands of clinical diagnostics, molecular biology, biotechnology, pharmaceutical research, academic laboratories, and industrial applications.
Our centrifuge tubes are manufactured with advanced polymer technology, precision molding, and rigorous quality control, ensuring optimal performance under high centrifugal forces and extreme laboratory conditions. Every tube is built to enhance reliability, reproducibility, and workflow efficiency.
What Are Centrifuge Tubes?
Centrifuge tubes are cylindrical laboratory containers specifically designed to hold liquid samples during centrifugation. They withstand high rotational speeds (RCF – Relative Centrifugal Force) while maintaining structural integrity and preventing leakage.
These tubes are commonly used for:
- Cell harvesting and pelleting
- DNA/RNA extraction and purification
- Protein precipitation
- Blood and plasma separation
- Microbial culture processing
- Chemical sample isolation
- Sample storage and transport
Designed with precision, centrifuge tubes allow laboratories to achieve consistent separation results without compromising sample integrity.
Types of Centrifuge Tubes for Diverse Laboratory Applications
We provide a comprehensive range of centrifuge tubes engineered to serve various laboratory workflows.
1. Conical Bottom Centrifuge Tubes
The most widely used format, conical centrifuge tubes, are ideal for pelleting applications. The conical base allows concentrated collection of sediments after centrifugation.
Common volumes include:
- 15 mL centrifuge tubes
- 50 mL centrifuge tubes
These tubes are widely used in cell culture, clinical labs, and molecular biology protocols.
2. Round Bottom Centrifuge Tubes
Round bottom centrifuge tubes offer uniform distribution of force during spinning and are ideal for specific separation procedures that do not require pellet concentration.
3. Microcentrifuge Tubes
For smaller volumes, microcentrifuge tubes (0.2 mL to 2 mL) are indispensable in molecular laboratories. They are optimized for:
- PCR preparation
- DNA amplification
- Enzyme reactions
- Sample aliquoting
High-clarity polypropylene construction ensures visibility and sample monitoring.
4. Graduated and Non-Graduated Centrifuge Tubes
Graduated centrifuge tubes provide precise volume measurement, improving experimental consistency. Clear, permanent markings enhance visibility and reduce errors in handling.
Material Excellence: Polypropylene and Advanced Polymers
Our centrifuge tubes are primarily manufactured from virgin medical-grade polypropylene (PP). This material is preferred because it provides:
- High chemical resistance
- Excellent transparency
- Autoclavability at 121°C
- Resistance to cracking under high RCF
- Low protein binding properties
Polypropylene ensures compatibility with organic solvents, acids, and biological samples, making it ideal for a wide spectrum of laboratory applications.
Leak-Proof and Secure Closure Systems
Reliable sealing is critical during centrifugation. Our centrifuge tubes are designed with:
- Leak-proof screw caps
- Flat-top caps for labeling
- Plug seal designs
- O-ring enhanced sealing (select models)
These advanced closures prevent aerosol formation and cross-contamination during high-speed centrifugation.
Withstanding High Centrifugal Forces (RCF Ratings)
A premium centrifuge tube must endure significant mechanical stress. Our tubes are validated to withstand high Relative Centrifugal Force (RCF) ratings without deformation.
Key features include:
- Thick, reinforced walls
- Precision-balanced molding
- Uniform wall thickness
- Crack-resistant design
These structural advantages ensure safe performance in fixed-angle and swing-bucket rotors.
Sterile, DNase/RNase-Free Options
For molecular biology and clinical diagnostics, contamination control is critical. We offer centrifuge tubes that are:
- Sterile (gamma irradiated)
- DNase-free
- RNase-free
- Pyrogen-free
- Non-cytotoxic
These features guarantee suitability for PCR, qPCR, nucleic acid extraction, and cell culture applications.
Temperature and Chemical Resistance
Laboratories often require extreme temperature cycling. Our centrifuge tubes are engineered to perform across a broad temperature range:
- -80°C for long-term storage
- Autoclavable at 121°C
- Resistant to repeated freeze-thaw cycles
Their superior chemical compatibility ensures stability when handling:
- Alcohols
- Organic solvents
- Acids
- Biological buffers
Precision Molding for Maximum Clarity and Strength
We employ advanced injection molding technology to ensure:
- High optical clarity
- Smooth inner surfaces for easy sample recovery
- Minimal sample adhesion
- Uniform thickness for balance during spinning
This precision engineering enhances experimental accuracy and reproducibility.
