This stainless steel lysing matrix tube with grinding ball is ideal for grinding, lysis and homogenization of resistant samples. Constructed from 308 SS, these tubes and grinding ball are tough enough to stand up to the most demanding mechanical punishment that can cause traditional thermoplastic tubes to crack. The tubes are machined from premium grade billet and deliver superior strength over less expensive production methods such as deep-drawn aluminum tubes. An oblique angle conical bottom provides a better impact surface than the rounded bottoms of deep-drawn tubes. The stainless steel threaded cap provides a leak-proof closure without the energy-robbing alternatives like plastic flange screw caps or rubber stoppers. A Teflon O-ring prevents leakage, and can be cleaned with detergent and/or autoclaving, or replaced entirely between samples. Machined knurls on the cap provide a firm grip to easy opening and closing.
