Selecting the correct mesh size is one of the most important decisions in any large-volume filtration workflow. Whether you are preparing environmental samples, isolating cell clusters, separating microplastics, or refining water samples, the mesh size determines what passes through, what gets retained, and how efficiently your process runs. For laboratories handling high sample volumes—anywhere from 100 ml to more than 10 liters—having a clear and practical approach to mesh selection can directly impact data quality, processing time, and downstream results.
This is where the pluriStrainer Maxi, a bottle-top strainer designed for high-volume filtration, becomes an essential tool. With 13 mesh sizes ranging from 5 μm to 2,000 μm, color-coded housings, a high-flow channel system, and the ability to stack multiple strainers to create a cascade, the pluriStrainer Maxi offers flexibility for almost any workflow. But the real value comes from knowing how to select the right mesh size for your application.
This article outlines a straightforward approach to mesh size selection and explains how the pluriStrainer Maxi enhances efficiency, control, and accuracy across diverse filtration needs. The goal is simple: help researchers and businesses choose the right mesh size while improving outcomes using one of the best Lab Cell Strainers available today.

Why Mesh Size Matters in Large-Volume Filtration

Mesh size determines:
The size of particles retained


The flow rate during filtration


How clean the final sample is


The consistency of downstream processes


A mesh that is too small can slow down filtration or clog prematurely. A mesh that is too large may allow unwanted particles to pass through and reduce sample purity.
For labs performing cell enrichment techniques, environmental analysis, or microplastic separation, choosing the right mesh size is not only about retention—it is also about operational efficiency.
Because large-volume filtration requires stability, reliability, and the ability to run unattended if needed, the pluriStrainer Maxi’s design—including its built-in ports for low-pressure systems and automated refilling, supports long filtration sessions without constant manual supervision.
Understanding the pluriStrainer Maxi Mesh Size Range
The pluriStrainer Maxi provides 13 mesh sizes, from very fine (5 µm) to very coarse (2,000 µm). These sizes cover a wide variety of applications, making it one of the most versatile options among Lab Cell Strainers.
Available mesh sizes (color-coded):
5 µm


8 µm


10 µm


15 µm


20 µm


30 µm


40 µm


70 µm


100 µm


200 µm


350 µm


500 µm


2,000 µm


Color coding makes it easy to avoid mix-ups, especially when running multiple filtration steps or cascade straining setups.

How to Choose the Right Mesh Size: A Step-by-Step Guide
Step 1: Define Your Goal
Start by clarifying what you aim to achieve:
Removing debris from cell suspensions


Collecting cell clusters or spheroids


Separating microplastics by size


Filtering large-volume water or soil suspensions


Preparing samples for downstream cell enrichment techniques


Performing cascade straining for detailed fractionation


Each goal requires a different mesh size strategy.

Step 2: Understand the Characteristics of Your Sample
Key factors include:
Particle size distribution


Expected concentration


Viscosity


Presence of aggregates or fibrous material


Need for gentle handling


For example, environmental water samples often contain large debris and fine particles in the same volume. Cell culture media typically contain smaller particles and require gentle processing to preserve cell viability.

Step 3: Match Mesh Size to Application
Here is a practical breakdown of mesh size selection based on common applications:

1. Cell Culture and Cell Suspension Filtration (30–100 µm)
For routine filtration of:
Cell cultures


Buffers


Media


Sera


Common mesh choices include 40 µm, 70 µm, and 100 µm.
These mesh sizes remove aggregates or debris while maintaining high flow rates. The pluriStrainer Maxi’s high-flow channel system helps prevent clogging and speeds up filtration.

2. Enrichment of Cell Clusters or Spheroids (70–200 µm)
Researchers working with:
Stem cell clusters


Organoids


Tissue-derived aggregates


often need to retain or separate specific size fractions.
Mesh options such as 70 µm, 100 µm, and 200 µm allow selective retention and controlled enrichment. Using multiple stacked pluriStrainers makes cascade straining easy, letting you break down mixed-size clusters into distinct groups.

3. Microplastic Analysis (30–500 µm)
Microplastic work requires precise size-based filtering.
Fine particles typically pass through 30–70 µm meshes, while larger plastics are captured by 100–500 µm meshes.
The pluriStrainer Maxi provides the flexibility needed for this growing research area, especially when analyzing large volumes of environmental water.

4. Agricultural Sample and Soil Runoff Filtration (100–2,000 µm)
Agricultural and environmental samples often contain:
Fibrous plant material


Sand and soil particles


Organic debris


Meshes between 350 µm and 2,000 µm are ideal for removing these larger components quickly without slowing the flow.

5. Environmental Water Analysis (5–100 µm)
Wastewater and freshwater often include particles across a broad range.
Fine filtration, such as 5 µm to 20 µm, helps remove micro-debris or small organisms. Larger meshes, such as 40–100 µm, remove bigger impurities first.
Combining these in a filter cascade improves clarity and makes downstream analysis more reliable.
Using Cascade Straining to Improve Accuracy
One of the most valuable features of the pluriStrainer Maxi is stackability. When working with large volumes, a single mesh size often isn’t enough. Cascade straining allows:
Sequential size separation


Consistent fractionation


Faster processing, since large debris is removed first


Improved control in cell enrichment techniques


For example, a sample can be processed through:
500 µm mesh to remove large debris


100 µm mesh for medium particles


40 µm mesh for final refinement


Cascade workflows are widely used in environmental testing, microplastic analysis, and complex cell preparations.
How the pluriStrainer Maxi Improves Large-Volume Filtration
Mesh size selection is only effective if the filtration device supports high throughput and consistent flow. The pluriStrainer Maxi includes several features that help achieve this.
1. High-flow channel system
A unique channel structure keeps flow rates high and reduces clogging even with finer mesh sizes.
2. GL45 Compatibility
It fits any GL45 bottle, which is a standard in most labs. With adapters, it also works with GL32 and GL80 bottles.
3. Supports manual or automated filtration
The special lid includes a tubing port for:
Low-pressure filtration


Automated refilling


Reduced hands-on time


This is especially helpful for processing several liters of sample.
4. Funnel compatibility
When handling samples between 1–10 liters, the funnel increases holding capacity and prevents overflow.
5. Color-coded mesh sizes
Researchers can quickly select and verify the correct mesh size, reducing errors and saving time.
6. Stackability
Direct stacking allows cascade filtration to be done in a single setup. This makes pluriStrainer Maxi ideal for labs performing detailed particle size separation or multi-step purification.
