Microcentrifuge Tubes
Microcentrifuge tubes are designed for small-volume sample processing, storage, and centrifugation in molecular biology, clinical, and research laboratories. Available in volumes ranging from 0.2 mL to 5 mL, these tubes are ideal for applications such as PCR preparation, sample aliquoting, and micro-scale centrifugation. Manufactured from high-quality polypropylene, microcentrifuge tubes provide chemical resistance, clarity, and durability under high-speed centrifugation. Offered in both standard snap-cap and secure safe-lock formats, these tubes help ensure sample protection, minimize evaporation, and maintain integrity during handling and processing.
Selecting Microcentrifuge Tubes for Your Workflow
Choosing the right microcentrifuge tube is essential for maintaining sample integrity, ensuring compatibility with equipment, and achieving reliable results in small-volume workflows.
Volume range:
Microcentrifuge tubes are available from 0.2 mL to 5 mL, supporting a wide range of applications from PCR setup to sample storage and processing.
Standard vs. safe-lock caps:
Standard snap-cap tubes are suitable for general laboratory use, while safe-lock tubes provide a more secure closure to prevent accidental opening during centrifugation or heating.
Material:
Polypropylene construction offers excellent chemical resistance and the ability to withstand high centrifugal forces and temperature variations.
Sterility:
Sterile microcentrifuge tubes are recommended for molecular biology, microbiology, and clinical applications where contamination must be minimized.
Seal integrity:
Secure caps help prevent leakage, evaporation, and sample loss during centrifugation and storage.
Graduations and labeling:
Clear volume markings and writable surfaces support accurate measurement and sample identification.
Compatibility:
Designed to fit standard microcentrifuge rotors, racks, and laboratory equipment.
For most laboratory workflows, maintaining a selection of microcentrifuge tubes across multiple sizes with both standard and safe-lock options provides flexibility and reliability for a wide range of applications.
