Feature of Conical Centrifuge Bottles
- Plastic centrifuge bottles are suitable for large-volume cell, immune cell, supernatant, bacteria, yeast and tissue sample separation, harvesting, etc. They can meet the requirements of bioanalysis, and are widely used in the field of life sciences and clinical experiments and other operations.
- The high chemical-resistance body of centrifuge bottle is made of medical standard polypropylene (PP) and the cap is made of high density polyethylene (HDPE).
- Bigger volume than centrifuge tubes for centrifuging procedure.
- Sdlabio centrifuge bottles can be used in the temperature range of -20℃~121℃, and withstand 121℃/15psi (15 min) autoclaving.
- Made in class 100,000 clean room, free of RNase, DNase, DNA and PCR inhibitors, tested Pyrogen free. EO ethylene oxide sterilization, SAL 10(-6).
Polycarbonate vs. Polypropylene Centrifuge Bottles
Polycarbonate Centrifuge Bottle
If you need high transparency, strong impact resistance, and the sample requires high centrifugal force (such as 50,000g) for applications such as cell culture, protein separation, biopharmaceuticals, etc., choose PC centrifuge bottle .
Polypropylene Centrifuge Bottle
If your experiment involves chemical reagents, especially organic solvents (such as acid and alkali environments), and does not require extremely high centrifugal forces. PP material is more resistant to chemical corrosion and is suitable for a wider range of experimental environments.

FAQ of Lab Centrifuge Bottles
What is the main applications of sterile centrifuge bottles?
- Cell seperation: Centrifuge bottles are commonly used to separate adherent cells or to separate cells from suspension during cell culture.
- Bacterial collection: Used for centrifugation to collect bacterial cultures in molecular biology and microbiology experiments.
- Sediment Concentration: Due to the conical design, the sediment is concentrated in the tip area at the bottom of the bottle during centrifugation, facilitating subsequent processing and analysis.
- Sample clarification: After tissue homogenization or cell lysis, the cone-bottomed bottle is used to remove insoluble particles to clarify the sample.
- High-speed centrifugation: In applications requiring high-speed centrifugation, such as isolation and purification of viral particles, plasmid DNA, exosomes, etc.
- Large-scale sample processing: Large-capacity conical bottom bottles are suitable for processing larger volumes of samples, e.g. during protein expression and purification.
- Cryogenic centrifugation: Centrifugation is performed at low temperatures to precipitate proteins or other biomolecules.
- Compatible with automation: The conical bottom of centrifugal bottles is designed to be for automated systems, such as automated liquid handling systems.
- Quality Control: Used to ensure purity and concentration of samples during quality control of biopharmaceutical and cell therapy products.
How to use centrifuge bottles?
- Pour the liquid sample into the centrifuge bottle, making sure the sample volume does not exceed the maximum capacity marked on the bottle.
- Choose the appropriate centrifuge rotor based on the sample type and centrifuge bottle capacity. Make sure the centrifuge speed matches the centrifugal force of the centrifuge bottle.
- Balance the centrifuge bottles to ensure that the two bottles are of equal weight to avoid imbalance during centrifugation.
- Set the speed and time of the centrifuge and start the centrifugation operation. Pay attention to monitor the temperature and time during the centrifugation process to avoid over-centrifugation.
- After centrifugation, remove the centrifuge bottle and take out the sample in time. If further analysis is required, use a pipette or reagent bottle to take the sample.
Can centrifuge bottles be used for frozen storage?
Some centrifuge bottles (especially those made of PP) can be used for low-temperature storage and are suitable for short-term frozen storage of samples. However, freezing may affect the centrifugation effect of some samples, and long-term frozen storage in cryovials is recommended.
