Each impact resistant 1.1 ml tube contains 0.5 ml dry volume of 0.5 mm & 0.1 mm ZymoBIOMICS BashingBead Lysis Matrix. Tubes are in twelve strips of eight as part of a 96-well rack, with strip caps and a plastic rack cover. The state of the art, ultra-high density beads are fracture resistant, chemically inert, and ideal for disrupting tough-to-lyse biological samples. These beads are ideal for microbes and fungi in soil, feces, sludge, etc. Heat seals are also provided to eliminate leakage during high-throughput homogenization.
