Manufacturer Description
The BioSpec Mini-BeadBeater-8 (Model 693) is a high-energy, high-efficiency cell disrupter designed for the rapid mechanical lysis of biological samples. Utilizing an aggressive, multi-directional shaking motion, this benchtop system forcefully agitates disposable microcentrifuge vials filled with small ceramic, glass, or steel beads. The Model 693 easily achieves 100% cell wall disruption of the most resilient matrices—including spores, yeast, fungi, and tough animal or plant tissues—typically in less than three minutes. Featuring a heavy, vibration-dampening cast metal base and a clear, high-impact safety hood, this unit delivers exceptional mechanical reliability and operator safety for daily nucleic acid and protein extraction workflows.
Technical Specifications
- Model Number: Mini-BeadBeater-8 (Model 693)
- Capacity: Processes 1 to 8 standard 1.5 mL or 2.0 mL microcentrifuge tubes simultaneously
- Speed Control: Variable speed adjustment dial ranging up to 3,200 RPM
- Timer Control: Integrated 0 to 5-minute manual dial timer with automatic shut-off
- Chassis Design: Heavy cast-alloy housing with a transparent, high-impact polycarbonate protective safety cover
- Drive Mechanism: Robust direct-drive motor assembly engineered for continuous laboratory service life
- Electrical Requirements: 115 VAC, 60 Hz (Standard US Outlet)
- Value-Add: Features an advanced variable-speed controller that enables fine-tuned adjustments, allowing operators to run lower speeds for gentle cell dispersion or maximum velocity for total disruption of tough plant cellulose or bone fragments.
System Compatibility
The Mini-BeadBeater-8 utilizes standard laboratory consumables, eliminating proprietary locking costs:
- Vial Formats: Fully compatible with standard 1.5 mL and 2.0 mL interlocking or screw-cap polypropylene microcentrifuge tubes.
- Lysis Media: Optimally accepts standard BioSpec glass (0.1–0.5 mm for bacteria), zirconia-silica (0.5 mm for yeast/spores), or chrome-steel beads (2.5 mm for fibrous tissue).
- Removable Stacker: The internal tube-holding rotor matrix can be completely removed for swift sample loading and post-lysis cleaning.
Applications
The premier choice for rapid sample preparation across academic and industrial laboratories:
- DNA/RNA Extraction: High-yield isolation of delicate nucleic acids from plant seeds, leaves, or animal biopsies without thermal degradation.
- Microbiology & Mycology: Absolute disruption of stubborn Gram-positive bacterial cell walls and thick chitinous fungal structures.
- Environmental Testing: Rapid processing of soil, sediment, and wastewater samples for metagenomic community profiling.
- Proteomics: Rapid release of active internal enzymes and proteins into extraction buffers for downstream Western Blot or LC-MS analysis.
