Exploring Varieties of Centrifuge Tubes: Types and Applications

15 ML Polypropylene Centrifuge Tube Wholesale Custom Factory

Centrifuge tubes Factory are indispensable tools in laboratory settings, utilized across various scientific disciplines for separating substances based on density gradients through centrifugal force. These specialized tubes come in a variety of types, each designed to meet specific research, diagnostic, or industrial needs.

1. Conical Centrifuge Tubes Factory:

Conical centrifuge tubes Factory, also known as sedimentation or pelleting tubes, are among the commonly used types. They feature a conical bottom that facilitates the sedimentation of denser particles or components during centrifugation. This design allows for efficient separation of solid particles or cellular components from liquids, making conical tubes Factory ideal for biological and biochemical applications such as cell culture, protein purification, and isolation of DNA or RNA.

2. Microcentrifuge Tubes Factory:

Microcentrifuge tubes Factory are smaller in size compared to standard centrifuge tubes and are designed to accommodate microvolume samples typically ranging from 0.5 mL to 2.0 mL. These tubes are compatible with microcentrifuges, which operate at high speeds to quickly separate small volumes of biological or chemical samples. Microcentrifuge tubes are commonly used in molecular biology, PCR (polymerase chain reaction), and protein analysis where rapid centrifugation and sample recovery are essential.

3. PCR Tubes:

Polymerase chain reaction (PCR) tubes are specialized microcentrifuge tubes designed specifically for PCR applications. These tubes are made from thin-walled materials such as polypropylene or polyethylene, which facilitate efficient heat transfer during PCR thermal cycling. PCR tubes are available in strip formats, where multiple tubes are connected in a single strip, allowing for simultaneous processing of multiple samples in PCR machines. These tubes are crucial in molecular diagnostics, genetic testing, and research involving DNA amplification.

4. High-Speed Centrifuge Tubes:

High-speed centrifuge tubes Factory are engineered to withstand the forces generated by high-speed centrifugation, often exceeding 10,000 revolutions per minute (rpm). These tubes are constructed from durable materials such as polypropylene or reinforced plastics to prevent deformation or rupture under centrifugal forces. High-speed centrifuge tubes are utilized in biochemical research, virology, and pharmaceutical development for isolating subcellular components, viral particles, and nanoparticles.

5. Graduated Centrifuge Tubes:

Graduated centrifuge tubes Factory feature volume markings along the side of the tube, allowing for precise measurement of sample volumes before and after centrifugation. These tubes are essential in quantitative analysis, where accurate determination of sample volumes is critical for experimental reproducibility and data interpretation. Graduated centrifuge tubes are commonly used in clinical laboratories for analyzing blood components, urine sediment, and other bodily fluids.

6. Fixed Angle Centrifuge Tubes:

Fixed angle centrifuge tubes Factory are characterized by their fixed angle of approximately 45 degrees between the tube axis and the plane of rotation. This design promotes efficient sedimentation of particles or components along the tube's bottom during centrifugation, pellet recovery and separation efficiency. Fixed angle centrifuge tubes are suitable for applications requiring gentle pelleting of biological materials, such as cell harvesting and organelle isolation.

7. Swinging Bucket Centrifuge Tubes:

Swinging bucket centrifuge tubes Factory are designed to swing outward as the centrifuge rotor spins, positioning the tubes horizontally during centrifugation. This swinging motion sample disturbance and allows for even distribution of centrifugal force across the sample, reducing the risk of sample stratification or mixing. Swinging bucket centrifuge tubes are used in clinical diagnostics, serology, and immunology for separating serum or plasma from whole blood samples.

8. Ultra-Centrifuge Tubes:

Ultra-centrifuge tubes Factory are engineered for ultracentrifugation applications, where centrifugal speeds exceed 100,000 rpm. These tubes are made from materials such as titanium or specialized polymers to withstand the forces and temperature fluctuations associated with ultracentrifugation. Ultra-centrifuge tubes are essential in biochemistry, structural biology, and biophysics for studying macromolecular complexes, membrane proteins, and molecular interactions at the atomic level.
