Plastic centrifuge tubes

Introduction to Plastic centrifuge tubes

Plastic centrifuge tubes are consumables used to contain samples and separate fractions in liquid mixtures under centrifugal force in laboratories. They are widely used in research and sample preparation protocols in molecular biology, microbiology, immunology, and cell biology.

When choosing plastic centrifuge tubes, users should consider criteria including capacity (commonly 15ml or 50ml), bottom shape (conical bottom for pellet collection or self-standing flat bottom), and plastic material such as PP or PS. In addition, depending on aseptic processing requirements and the rotor's maximum RCF rating, laboratories can choose sterile or non-sterile options, with graduations and writing areas. Hoa Viet currently supplies screw-cap plastic centrifuge tubes from manufacturers including Aptaca (Italy) and Jet Biofil (China).

Should I choose PP or PS plastic centrifuge tubes?

PP (Polypropylene) offers high mechanical strength, withstands high centrifugal forces, and can be autoclaved at high temperatures. In contrast, PS (Polystyrene) features superior transparency for clear sample observation, typically suited for routine lower-speed centrifugation applications.

What is the difference between conical bottom and flat bottom centrifuge tubes?

Conical bottom tubes help concentrate pellets and sample sediment at the bottom center after centrifugation, facilitating easy pellet recovery or supernatant aspiration. Flat bottom tubes offer the advantage of being self-standing on laboratory workbenches without requiring a dedicated tube rack.

Which type of centrifuge tube should be selected for cell culture and microbiology laboratories?

These applications should prioritize pre-sterilized tubes manufactured from materials meeting standards such as USP Class VI to prevent sample contamination. Depending on the frequency of use, users can choose individually wrapped sterile units or bulk packs.

Which brands of plastic centrifuge tubes does Hoa Viet distribute?

Currently, Hoa Viet supplies 15ml and 50ml plastic centrifuge tubes from two brands: Aptaca (Italy) and Jet Biofil (China). Contact us directly for in-depth technical advice and to Request a quote.
