Cell Disruption by High Pressure Homogenization | High Efficiency Cell Lysis Technology
What is Cell Disruption?
Cell disruption, also known as cell lysis, is a fundamental process in biotechnology used to break open cells and release intracellular components such as proteins, enzymes, nucleic acids, and viruses.
An efficient cell disruption technology ensures:
- High recovery yield of biomolecules
- Preservation of protein and enzyme activity
- Compatibility with downstream purification processes
It is widely applied in:
- Recombinant protein extraction
- Vaccine and biologics production
- mRNA, DNA, and viral vector processing
- Metabolite and nanoparticle recovery
- Life science and biomedical research
Key Challenges in Cell Disruption and Cell Lysis
Despite its importance in modern biotechnology, efficient cell disruption and cell lysis remain technically challenging.
Tough Cell Structures
Bacteria, yeast, algae, and plant cells contain rigid cell walls that are difficult to break.
Heat-Sensitive Biomolecules
Excessive shear force, friction, or poor temperature control may cause protein denaturation and loss of activity.
Inconsistent Lysis Efficiency
Traditional methods often suffer from batch-to-batch variability, leading to low reproducibility.
Scale-Up Limitations
Many laboratory methods fail to translate efficiently into pilot-scale or industrial production.
High Pressure Homogenizer for Cell Disruption
A High Pressure Homogenizer is one of the most efficient and scalable technologies for modern cell disruption and cell lysis applications.
Genizer systems force cell suspensions through a precision-engineered diamond interaction chamber under extremely high pressure. This process generates:
- Intense shear forces
- Turbulence effects
- Cavitation energy
These mechanical forces effectively rupture cell membranes while maintaining intracellular biomolecule integrity.

| Insect cells | Sf9, Sf21 | 600–1,000 bar (8,500–14,500 psi) | H10Z / H10Z-RT |
| Bacteria | E. coli | 800–1,000 bar (11,500–14,500 psi) | H10Z / H10Z-RT |
| Yeast | Yeast strains | 1,200–1,400 bar (17,500–20,000 psi) | H10Z / H10Z-RT |
| Algae | Green algae | 1,200–1,500 bar (up to 21,500 psi) | H10Z / H10Z-RT |
| Spores | Ganoderma | 1,300–1,600 bar (18,500–23,000 psi) | H10Z / H10Z-RT |
RT Chamber Technology for Sensitive Cell Lysis
The RT (Refrigerated Technology) chamber is designed for temperature-sensitive biological samples in cell disruption applications.
Benefits include:
- Continuous low-temperature operation (as low as 4°C)
- Protection of protein and enzyme activity
- Reduced thermal degradation
- Improved product stability and yield
