Guide and selection support
Centrifuge tubes are used to safely hold samples and prepare them for centrifugation, allowing for efficient separation of components under centrifugal force.
Selecting the right centrifuge tube involves considering material, volume, closure type, and compatibility with your centrifuge model. Sterility and chemical resistance requirements depend on the intended application.
LabFinder provides a clear overview of different centrifuge tube types, supporting targeted procurement for a range of laboratory and centrifuge applications.
Use and benefits
Centrifuge tubes are indispensable laboratory consumables designed to securely contain samples during centrifugation. They are widely used in areas such as molecular biology, microbiology, cell culture, and clinical diagnostics. Centrifugal force allows efficient separation of various sample components, such as cells, DNA, proteins, or particles.
Selection criteria
Key selection factors include volume (commonly 1.5 ml, 2 ml, 15 ml, or 50 ml), material (usually polypropylene), and closure type (open, snap cap, or screw cap). Compatibility with the specific centrifuge type and rotor system is necessary to ensure reliable sealing and sample safety. For sensitive or sterile samples, pre-sterilized or certified tubes may be required.
Variants and measurement principles
Centrifuge tubes vary by volume and closure design. Standard tubes and microcentrifuge tubes are available for different sample sizes. Screw caps offer enhanced leak resistance, while snap caps enable quick handling. Polypropylene tubes dominate due to their chemical stability and resistance to temperature changes. Sterile versions are available for applications needing high purity or aseptic processing.
Quality, storage and handling
Centrifuge tubes may be single-use or reusable. When reusing tubes, thorough cleaning and sterilization are essential to prevent contamination. Tube quality, including material purity and secure sealing, directly impacts sample integrity and centrifugation results.
Application limits
Centrifuge tubes are designed for defined speed and temperature ranges. Exceeding recommended conditions or using improper closures can cause sample loss or tube failure. For high-speed centrifugation or use with aggressive chemicals, specialized tubes should be selected.

Frequently asked questions
What are centrifuge tubes used for in the laboratory?
Centrifuge tubes are used to collect and securely store samples during centrifugation, enabling the separation of sample components by centrifugal force.
What types of centrifuge tubes are available?
There are tubes in various volumes (e.g., 1.5 ml, 15 ml, 50 ml) with different closures (snap cap, screw cap) and materials, primarily polypropylene.
What should be considered when choosing centrifuge tubes?
Important criteria include volume, material, closure type, compatibility with centrifuge systems, and, if needed, sterility level—based on your planned application and sample requirements.
Can centrifuge tubes be reused?
Depending on quality and intended use, some tubes are reusable if thoroughly cleaned and sterilized. However, many are designed for single use.
Are there special centrifuge tubes for high-speed or chemical resistance?
Yes. Specialized tubes are available for high centrifugation forces or use with aggressive substances, offering enhanced durability or chemical resistance.
