7 Mistakes Researchers Make During Tissue Dissociation (And How pluriStrainer® Fixes Them)
Tissue dissociation is one of the most important steps in preparing high-quality single-cell suspensions for downstream applications. Whether the goal is flow cytometry, primary cell culture, cell separation, or organoid research, the quality of the dissociation process determines how reproducible and reliable the data will be.
Yet even experienced researchers encounter the same recurring issues: clogged filters, inconsistent yields, large cell aggregates, and long processing times. Many of these problems happen not because of complex technical errors, but because of simple steps that become inefficient over time.
This is where the pluriStrainer® becomes a helpful tool. As a flexible and easy-to-use cell strainer, it simplifies tissue dissociation, prevents common mistakes, and saves valuable time. Whether you work with a 40 µm cell strainer, a 70 µm cell strainer, or a 100 µm strainer, having the right device makes tissue processing smoother and more predictable.
Here are the seven most common mistakes researchers make during tissue dissociation, and how pluriStrainer® fixes them.
Mistake 1: Skipping the Stepwise Filtration Process
Many researchers try to push tissue suspensions directly through a single mesh size—usually a 70 µm cell strainer, to save time. In reality, this slows the workflow because large debris and tissue fragments clog the mesh almost immediately.
How pluriStrainer® fixes it
pluriStrainer® devices are designed to be stackable, making it easy to build a Lab Strainer cascade using several pore sizes at once. A typical cascade might include:
100 µm strainer for large fragments
70 µm cell strainer for medium debris
40 µm cell strainer for fine preparation
This stepwise filtration reduces clogging, speeds up processing, and increases the final recovery of single cells. The ability to stack multiple strainers on the same tube ensures a smooth and efficient workflow without changing equipment between steps.
Mistake 2: Applying Too Much Force During Filtration
Pushing tissue with excessive pressure leads to:
Cell damage
Altered morphology
Lower viability
Mesh rupture
This often happens when strainers clog or when samples are too viscous.
How pluriStrainer® fixes it
With the Connector Ring attached, pluriStrainer® allows users to control flow rate through a simple open-and-close mechanism. You can slow the flow for gentle dissociation or allow faster passage when the sample is homogeneous.
For more challenging tissues like spleen, lung, or brain, researchers can connect a syringe to generate low pressure, pulling the liquid gently through the mesh without forcing or damaging the cells. This controlled flow protects fragile cells and results in better single-cell suspensions.
Mistake 3: Allowing Meshes to Clog Due to Poor Ventilation
One of the biggest frustrations during dissociation is when filters clog not because of debris, but because of poor airflow. Air pressure builds up under the mesh, blocking liquid flow and causing the sample to sit on top of the strainer.
How pluriStrainer® fixes it
pluriStrainer® is designed with improved ventilation to reduce clogging. This ensures continuous flow and prevents liquid buildup on the mesh surface.
Even sticky or viscous materials move through more consistently, making filtration faster and less frustrating. For high-volume samples, pluriStrainer® can be combined with a funnel to allow up to 24 mL of sample on top of the strainer without slowing down the process.
Mistake 4: Using Gauze or Improvised Filters
Some labs still rely on gauze, nylon mesh pads, or homemade filters to save costs. Unfortunately, these materials:
Trap large numbers of viable cells
Produce uneven mesh sizes
Introduce contaminants
Cause inconsistent results
Slow down processing time
How pluriStrainer® fixes it
pluriStrainer® offers:
Sterile, ready-to-use filters
Uniform and precise mesh sizes
Compatibility with all major 50 mL tubes
Options ranging from 70 µm to 500 µm
This provides consistent and reliable filtration with fewer lost cells and fewer repeated dissociation attempts. It is simply a faster and more predictable alternative to gauze-based filtration.
Mistake 5: Losing Valuable Cell Fractions During Filtration
Many researchers forget that sometimes the larger tissue fraction may contain intact cell clusters that are still useful. Standard strainers make it difficult to recover this material.
How pluriStrainer® fixes it
pluriStrainer® can be inverted to recover the retained material. A quick flush with buffer releases the trapped fraction without contamination or mechanical damage.
This is especially helpful when working with:
Mammary tissue
Organoids
Bone marrow
Tumor samples
Lymphoid tissues
By turning the strainer upside down onto a fresh tube, you easily recover the material that would normally be discarded. This ensures higher cell yield and more comprehensive downstream analysis.
Mistake 6: Ignoring the Importance of Mesh Size Variability
Using only a single mesh size (for example a 70 µm cell strainer) prevents optimization of cell yield and homogeneity. Different tissues and applications require different pore sizes.
For example:
A 100 µm strainer is best for coarse dissociation
A 70 µm cell strainer is ideal for lymphoid tissues
A 40 µm cell strainer prepares samples for flow cytometry
Finer meshes help remove aggregates before magnetic separation
How pluriStrainer® fixes it
pluriStrainer® is available in a wide range of pore sizes, including:
70 µm
100 µm
200 µm
300 µm
400 µm
500 µm
Labs that require fine preparation can combine pluriStrainer® with Mini Strainer formats such as the Cell strainer 40 µm and Cell strainer 70 µm for small-volume processing.
Having the correct mesh size at every stage leads to:
Better single-cell suspensions
Fewer aggregates
Easier downstream separation
Cleaner flow cytometry plots
Mesh size flexibility is one of the biggest reasons pluriStrainer® saves time and improves purity.
Mistake 7: Not Using Filtration as Part of the Tissue Dissociation Process
Many researchers see filtration only as a final cleanup step. But effective dissociation starts with filtering at the right moments, not just at the end.
During dissociation, samples often require:
Intermittent clearing of debris
Removal of partially digested material
Separation of tissue layers
Short incubation with reagents
Controlled mixing and flow
How pluriStrainer® fixes it
pluriStrainer® allows users to hold liquid on top of the mesh by blocking the flow. This makes it possible to:
Incubate tissue fragments with enzymes directly on the strainer
Perform short treatments (e.g., TRIzol®, Buffer RLT)
Dissociate primary tissues physically
Break up clusters while maintaining sterile conditions
This transforms filtration from a simple step into an active part of the dissociation workflow.
The ability to combine the strainer with the Connector Ring and a syringe also supports physical dissociation of tough tissues like:
Brain
Spleen
Pancreas
Thymus
Lymph nodes
Researchers can guide dissociation with gentle low pressure, improving the final quality of the single-cell suspension.
