Micro Centrifuge Tubes

Snap cap microtubes, also known as microcentrifuge tubes, are single-use containers designed to hold small liquid volumes ranging from microliters to milliliters. Available in both sterile and non-sterile formats, these tubes can be equipped with a variety of closure styles such as snap, screw, or tethered caps, and are suitable for use in microcentrifuges and other laboratory applications.

These high-quality polypropylene tubes are essential for the safe handling and processing of low- to medium-volume samples in clinical chemistry, biochemistry, and molecular biology. They are ideal for protein research, mass spectrometry, sample preparation, microcentrifugation, and sample storage. Options include colored tubes such as amber or black for light-sensitive samples.

The snap cap design ensures a secure, liquid-tight seal, while select models feature a flat top with a needle insertion point for added convenience. For enhanced safety, some tubes come with a lockable snap cap to prevent accidental opening during centrifugation—ideal when handling radioactive or biohazardous materials.
