Qiagen 85210 TissueLyser Homogenizer

The Qiagen 85210 TissueLyser serves as a versatile bead-mill homogenizer built for rapid, high-throughput disruption and biological lysis. Qiagen developed this benchtop system alongside Retsch to accelerate sample preparation. It combines high-speed oscillation with durable grinding beads to disrupt tough animal tissues, plant matter, bacteria, yeast, and fungi, directly streamlining downstream nucleic acid and protein purification.

Operating Principle & Mechanism

The TissueLyser operates through high-frequency radial oscillation. To begin, operators clamp sealed sample tubes—containing tissue, buffer, and grinding beads—securely into adapter sets. Next, the arm oscillates between 3 and 30 Hz. Consequently, rapid bead impact shears and homogenizes tough specimens within minutes without degrading sensitive DNA or RNA.

Key Technical Specifications & Features of the Qiagen 85210 TissueLyser

• Throughput Flexibility: Capable of processing up to 2 × 96 standard microplates or up to 48 microcentrifuge tubes (1.5 mL or 2.0 mL) simultaneously using dual adapter sets.
• Oscillation Frequency: Variable speed control ranging from 3 to 30 Hz (180 to 1800 oscillations per minute) for reproducible energy transfer.
• Run Time Control: Digital timer settings adjustable from 10 seconds up to 99 minutes.
• Contamination Control: Sealed tube processing eliminates sample cross-contamination and aerosol release compared to traditional rotor-stator homogenizers.
• Cryogenic Capability: Compatible with adapter sets that can be pre-chilled in liquid nitrogen or dry ice, protecting thermolabile analytes during mechanical disruption.

Target Applications

The system is optimized for molecular biology workflows requiring standardized, high-yield extraction:

• Genomics & Transcriptomics: Isolation of intact genomic DNA and total RNA from fibrous, elastic, or tough tissues (e.g., heart, skin, seeds, roots).
• Proteomics & Metabolomics: Rapid cellular disruption for protein extraction and small-molecule metabolite analysis.
• Microbiology: Efficient cell wall lysis of Gram-positive bacteria, yeast, and fungal spores without manual enzymatic pre-treatment.

Qiagen 85210 TissueLyser Workflow Integration

The Qiagen 85210 TissueLyser integrates directly into standard manual and automated purification pipelines. In addition, its microplate footprint matches automated liquid handlers like QIAsymphony and KingFisher platforms. Finally, a built-in safety interlock stops all movement whenever you open the hood, ensuring safe everyday operation.
