WaysideLab 1.5mL Loop-Cap Screw-Cap Microtube, Conical Bottom, Sterile, 10 Bags of 100 Tubes, 1000/case Leakproof Centrifuge Tube

Description

SureSeal sterile screw-cap microtubes are engineered to offer superior sealing performance and sample visibility across a range of laboratory applications. Made from ultra-clear, high-quality polypropylene, these tubes provide secure, leakproof storage and transport of valuable samples—even under demanding thermal and centrifugal conditions.

Each tube comes pre-assembled with a precision-molded screw cap featuring a durable silicone O-ring that ensures a tight, leakproof seal from -90°C up to +121°C. Whether you're storing biological samples in extreme cold or sterilizing via autoclave, SureSeal microtubes are built to perform. Their resistance to high-speed centrifugation—up to 22,000 × g—makes them a reliable choice for critical research.

Available in a variety of volumes, with molded graduations or non-graduated options, and also offered in light-blocking amber to protect light-sensitive materials, these microtubes are sterile, RNase, DNase, and pyrogen free to preserve sample integrity in molecular biology, biochemistry, or clinical labs.
