Solutions for Cell Disruption
Introducing the all new Microlyser™ Production Scale Cell Disruptor
The MP350 Enhanced Biopharma Grade Microlyser™ processor delivers uniform pressure up to 30,000 PSI. This hybrid solution maximises protein yields and ensures high product quality in cell disruption of various cell types including bacterial, yeast and algae.
The Microlyser™ Processor has the same multi-slotted fixed-geometry Interaction Chambers™ that all Microfluidizer equipment possesses, ensuring repeatable results batch-to-batch at production volumes.
Cell disruption is the process of breaking cell wall and/or membrane to release intracellular fluids containing molecules or particles of interest, such as proteins or viruses. The primary goal of cell disruption is to lyse the suspended cells and recover the maximum possible viable yield of the molecules/particles of interest.
Microfluidizer® cell disruptors are ideally suited to rupturing various cell types, including bacterial (gram positive and gram negative), yeasts, insect, mammalian (release of virus for Gene Therapy), plant and algae cells, due to the wide and controlled shear rate range they can apply to the sample. This control of the shear rate enables researchers to optimise the process parameters to achieve effective rupture rates while minimising the excess energy introduction to the system and avoiding denaturation of delicate proteins.
Microfluidizer® cell disruptors offer a number of advantages over other methods of homogenisation, including High Pressure Homogenisers. View an application note which provides an overview of cell disruption techniques and why Microfluidizer® processors are best suited for cell disruption.

Cell Disruptors
The LM20 is an ideal Microfluidizer for cell disruption; digitally controlled, it has a maximum process pressure of 30,000 psi enabling it to handle the toughest cell types.
The LM10 enables extremely fast, easy and consistent processing of all cell suspensions. Digital control enables repeatability between sample batches and simple operation.
The above Microfluidizer models are the most popular for cell disruption amongst our customers’ applications, however other Microfluidizers are available.
Microfluidizers handle disruption of E.Coli and other bacterial cell lines easily. Typically sufficient lysis is achieved in 1 pass at moderate process pressures, minimizing excess energy and heat in the system and enabling excellent recovery of viable protein.

Insect cells, such as Sf9, are comparatively easy to disrupt compared to Bacteria and Yeasts; Microfluidizers enable fast, consistent processing at moderate pressures usually requiring a single pass for superior lysis.

The easiest cell type to disrupt; when required processing of these cell needs to be handled gently to preserve viral vectors such as AAVs, typically as part of a Gene Therapy production process. Mild conditions are used; yield, scalability and easy downstream filtration are among the main benefits for using Microfludizer technology for this application over freeze-thaw or chemical lysis methods.

Algae cells such as Diatoms and various other naturally occurring species can be successfully lysed on a Microfluidizer with varying conditions for research, ingredient harvesting or biofuel purposes.
Microfluidizer® Processor Laboratory Results
| Industry | BioTech Company F |
| Product | A 10% wt. dispersion of algae cells suspended in water. |
| Test Objective | To rupture the cells in order to free the oil that is contained inside. |
| Processor | M-110S |
| Chambers | • G10Z (87 microns) |
| No. of Passes | 3 |
| Process Pressure | 20,000 psi |
| Process Procedure | The algae cells were suspended in water at a concentration of 15% wt. cells when they arrived. The original concentration was very viscous, such that it was diluted down to approximately 10% wt. before processing. The samples were processed on the M-110S Microfluidizer processor for one – three passes at 20,000 psi. A sample was taken after each pass and analysed. |
| Summary of Results | The optical microscopy results from the analysis can be found in Figure 1. |

The LM20 Microfluidizer processor offers superior lysis over traditional methods of cell disruption with an efficient system to reduce internal blockages. The scalability of the design means that the forces experienced by cells will not change if the sample volume increases. I can, therefore, have confidence that the sample quality, yield and processing times won’t be impacted by scaling up my lab processes.
Digital controls allow the system pressure to be set more easily and accurately compared to alternative manual processors, reducing the potential for errors and increasing reproducibility.
Analytik’s in-depth user training, and easy operation/maintenance procedures have been extremely beneficial. I feel confident to troubleshoot and perform preventative maintenance without having to call the support teams – it doesn’t feel like a ‘black box’ machine.
I would recommend the LM20 Microfluidizer as an essential tool for cell disruption.
James Wright, Protein Scientist at Abcam Plc
We approached Analytik to find a replacement for a high-pressure homogeniser from another manufacturer, which had been unreliable and failed to achieve sufficient lysis of our tough yeast cells even after very many passes. We selected the LM20 Microfluidizer not only because it efficiently lysed a broad range of cell types but also was incredibly simple and easy to use which is very important as many different people need to use the machine regularly.
We also much appreciated the knowledgeable technical and applications support provided by Analytik which has enabled us to fully exploit the considerable capabilities of the LM20 Microfluidizer.
