Centrifuge Tube 15ml Conical Bottom Sterile - Box of 1000

These 15ml conical bottom centrifuge tubes are sterile and come in a bulk box of 1000. They're designed for high-speed centrifugation, sample preparation and storage in clinical, research and industrial laboratories. Each tube has a clear barrel for visual inspection, bold black graduations for reading volumes and a large white writing area for labelling samples.

Leak-proof flat caps prevent evaporation and contamination during vortexing or long-term storage. The tubes are certified sterile, DNase/RNase-free and non-pyrogenic, which protects sensitive assays from contamination. With 1000 tubes per box, they're a cost-effective choice for high-throughput testing.
