Guide and selection support
Microcentrifuge tubes are primarily used for precision tasks such as DNA amplification, sample preparation, and centrifugation steps. Their ability to hold small volumes makes them standard tools for daily laboratory routines.
When selecting microcentrifuge tubes, key factors include volume, material characteristics, and closure type, ensuring compatibility with devices such as microcentrifuges and PCR cyclers. Chemical resistance and performance under different temperature conditions are also important.
LabFinder provides a structured overview of microcentrifuge tubes—including information on sizing, types, and application-related properties—to streamline sourcing within complex laboratory workflows.
Use and benefits
Microcentrifuge tubes are small laboratory vessels designed for collecting, mixing, and reacting with small sample volumes. Typical uses include molecular biology procedures such as PCR, DNA and RNA analysis, enzymatic assays, and microbiological testing. Because they accommodate volumes from approximately 0.2 ml to 2 ml, these tubes are ideal for precise experimental processes in research and diagnostics.
Selection criteria
Key aspects in choosing microcentrifuge tubes include suitable volume (commonly 0.5 ml and 1.5 ml sizes), transparent, chemically-resistant plastics such as polypropylene, and closure systems ranging from snap caps to screw tops, depending on sealing needs and storage conditions. Compatibility with laboratory devices like microcentrifuges and thermal cyclers, as well as resistance to temperature variation, should also be considered.
Variants and measurement principles
Microcentrifuge tubes are available in different styles, such as flat-bottom or round-bottom designs. Round-bottom tubes facilitate sample recovery and are especially useful for centrifugation. Some variants offer locking mechanisms or enhanced sealing for specific laboratory requirements. Standard sizes of 0.5 ml and 1.5 ml cover a wide range of applications.
Quality, storage and handling
These products are single-use items, with quality defined by material purity and the absence of contaminants. Depending on use, tubes can be supplied sterile or non-sterile. Store in a dry, light-protected environment to preserve material properties.
Application limits
Microcentrifuge tubes are not suited for large volumes or tasks requiring high mechanical strength. They may not be compatible with all chemical agents or withstand extreme temperatures. Limitations related to maximum centrifugation speeds or temperature exposure must be considered to avoid tube deformation or sample loss.

Frequently asked questions
What are microcentrifuge tubes used for in the lab?
They are used for handling and processing small sample volumes, mainly for molecular biology tasks such as PCR, enzymatic reactions, and for centrifugation steps.
What types of microcentrifuge tubes are available?
Typical types vary by volume (for example, 0.5 ml or 1.5 ml), base shape (flat or round), material, and closure design (snap cap, screw cap).
How do I select the right microcentrifuge tubes?
Selection depends on compatibility with lab equipment like microcentrifuges, desired volume, material resistance to chemicals and temperature, and the sealing mechanism.
Can microcentrifuge tubes be reused?
They are typically designed as disposable to avoid cross-contamination. Reuse is possible with certain materials and applications, but is generally not recommended.
What are the limitations of microcentrifuge tubes?
They are unsuitable for large volumes, highly aggressive chemicals, or temperatures beyond their specified range. Mechanical stresses such as high centrifugation forces should also be considered.
