Laboratory Consumables Centrifugal Tube

Centrifuge tubes are small containers widely used in laboratories, mainly used with centrifuges for centrifugal separation, sedimentation, concentration, mixing and short-term storage of liquid samples. They can separate solid and liquid, layer and purify samples by centrifugal force under high-speed rotation, serving as basic consumables in chemistry, biology, medicine, food inspection and other fields.

1.Transparent material for clear observation of sample status, usually made of polymer materials such as polypropylene (PP).
2.Resistant to low and high temperatures, suitable for cryogenic storage, autoclaving and routine centrifugation.
3.Good sealing performance with screw caps or snap caps to prevent leakage and cross-contamination.
4.Clear scales on the tube wall for rough quantitative measurement and easy operation.
5.High chemical stability, resistant to acids, alkalis and organic solvents, compatible with various samples.
6.Moderate mechanical strength, stable under high-speed centrifugation without easy deformation or breakage.

1.Biological sample processing, such as separation and precipitation of blood, cells, bacteria, nucleic acids and proteins.
2.Mixing, extraction, concentration and short-term cryogenic storage of laboratory samples.
3.Clinical medical testing, disease control inspection, food safety analysis and environmental monitoring.
4.Widely used in universities, hospitals, third-party testing institutions, pharmaceutical and biotechnology laboratories.

Common centrifuge tubes are classified by material, which varies in compatibility with rotation speed, temperature and chemical conditions. The main types are as follows:
1. PP (Polypropylene)
The most widely used and cost-effective
Low-temperature resistant (storable at -80°C) and autoclavable
Good chemical stability, resistant to most acids, alkalis and alcohols
Suitable for routine centrifugation, sample storage and molecular biology experiments
2. PC (Polycarbonate)
High transparency and strong mechanical strength
Autoclavable and heat-resistant
Not resistant to strong alkalis or phenol solvents
Suitable for scenarios requiring clear observation and medium-high speed centrifugation
3. PFA (Perfluoroalkoxy Alkane)
Corrosion-resistant, ultra-pure and high-temperature resistant
Repeatedly autoclavable with excellent chemical stability
Relatively high cost
Suitable for trace analysis, strong acid/alkali systems and high-purity samples
4. PE (Polyethylene, LDPE/HDPE)
Soft and tough
Low-temperature resistant with good chemical stability
Low transparency; not autoclavable
Suitable for low-temperature storage and low-speed centrifugation
5. PET (Polyethylene Terephthalate)
High transparency and rigidity
Mostly for single use, generally not autoclavable
Low cost
Suitable for clinical blood collection and rapid single-use centrifugation
6. PA (Polyamide)
High toughness and impact resistance
Rarely used as the main tube body; mostly for accessories or special purposes
7. Glass Centrifuge Tubes
High-temperature resistant, corrosion-resistant, washable and autoclavable
Fragile and not suitable for high-speed centrifugation
Sitable for high-temperature drying, strong organic solvents and highly clean experiments
