Collection: Homogenizers & Cell Disruption

Bead mills shake samples with grinding beads and excel at tough tissue, yeast, and batch processing in sealed tubes. Rotor-stator homogenizers shear samples in seconds and are gentler on high-molecular-weight DNA. Sonication uses cavitation — strong for bacterial lysis and chromatin or DNA shearing, but it fragments nucleic acids indiscriminately. Choose by sample type, throughput, and which analyte must survive intact.

Small glass beads (roughly 0.1–0.5 mm) suit bacteria and yeast; larger zirconia or ceramic beads handle soft and fibrous tissue; stainless-steel beads crush the toughest samples such as plant material, seeds, and bone. Prefilled tube kits remove the guesswork of matching bead, tube, and sample. Benchmark offers bead kits across these materials for its BeadBug and BeadBlaster systems.

Bead impacts generate heat quickly, so run short cycles with rest intervals on ice and prechill tube carriers. For RNA work and heat-labile enzymes, the BeadBlaster 24R adds built-in refrigeration so lysis runs stay cold without interruptions. Sealed screw-cap tubes also prevent aerosol loss during cooling transfers.

Yes — probe sonication is a standard method for shearing chromatin and DNA, with fragment size tuned by power, time, and duty cycle. Benchmark's Pulse 150 targets cell lysis and ChIP-style shearing and ships with a soundproof enclosure and 6 mm horn. Keep samples on ice between pulses to limit heat damage.

Israeli labs source the Benchmark Scientific homogenizer line — BeadBug and BeadBlaster bead mills, the D1000 rotor-stator, and Pulse sonicators — through Danyel Biotech, the brand's official distributor in Israel.
