The Radnoti micro homogenizer line uses a conically shaped tube to promote efficient homogenization and pellet formation after centrifugation. The vessel and pestle are designed to provide efficient manual or motorized grinding for small sample volumes. These micro homogenizers also function as micro reaction tubes and can be capped and sealed for freezer storage (the standing model is an ideal storage vessel). The conical tubes have been run at 7,000g for one hour. The standing models are suitable for only very low speed centrifugation. Three sizes are available in both the standing and conical models. Two homogenizers per box.
