Accurate
to 0.1% of bubble point
Direct, reliable, versatile through-pore measurements made simple, from R&D to QC.
By measuring true through pores directly, without curve fitting or model assumptions, AccuPore delivers reproducible pore size distributions, accurate bubble point values, and meaningful mean flow pore sizes that translate directly to real-world performance in the right timescales.
Its flexible pressure ramp and step modes allow researchers to rapidly screen new materials during development, while the same robust, standardized measurements ensure consistent, audit-ready quality control of membranes, filters, and separators in routine manufacturing environments.
Key features and benefits
アプリケーション
電池・燃料電池用セパレータ・メンブレン
Optimize the rate of ion transport and physical separation to ensure device safety. Precision sample supports and advanced pressure control enable accurate measurements up to high pressure for small pores and thin membranes.
ろ過
Predict and ensure size-based selectivity and mass-transfer rate by optimizing the number and size of pores.
不織布
Often characterized by a broad distribution of pore sizes due to their production methods. These are common choices for filtration media. In-plane porosity and irregular pore shapes make steady flow determination of bubble point especially important.
金属とセラミックス
Preferred for thermal, physical, and chemical resistance, these materials often have highly porous structures. The three-dimensional porosity of these materials makes it especially important to measurement porosity in the direction of intended flow.
Versatility
Load any sample and get reliable data - no complex setup required.
Measure 13mm, 25mm, and 47mm-diameter samples within the same sample chamber, with no need for fixture swaps or recalibration. From delicate membranes to high strength separators, R&D to QC, AccuPore handles it all without needing expert-level setup or method development.

よくあるご質問
Porometry and porosimetry are two different methods for analyzing porous materials. Porometry identifies through-pore diameters and flow traits like bubble point and permeability, whereas porosimetry (particularly mercury intrusion) measures total pore volume, density, and the size distribution of all connected pores.
Distinct in their approach, porometry characterizes through-pore size distribution and flow properties, whereas porosimetry (mercury intrusion) evaluates the total volume, density, and size distribution across all connected pores.
- Accurate, repeatable and direct measurements of bubble point and largest pore size
- Best resolution of through-pore size distribution, with greatest sensitivity for smallest pores
- Flexible by design: Smart switch of gas supply for the widest dynamic pressure range in a single instrument. AccuPore handles diverse sample types and sizes, and it also allows customizable test routines
- Intuitive software enables easy and quick setup for accurate measurements without complexity
Any industry that needs to control, measure, or validate through-pore size distribution, flow, and bubble pointy can benefit from AccuPore—especially where product safety, performance, and consistency are critical.

Porosity and pore size distribution describe different but complementary properties of a porous material. Porosity refers to the total amount of empty space within the material, usually expressed as a percentage, indicating how much fluid or gas it can hold overall. In contrast, pore size distribution describes the range and frequency of pore sizes present, showing whether the material has mostly small, large, or a mix of pores and how they are spread. While porosity tells you how much void space exists, pore size distribution tells you how that space is structured, which is crucial for determining how fluids flow through the material and what particle sizes can be filtered.
