Benefits

EASY, ACCURATE, MOST VERSATILE MEASUREMENTS

• High resolution, low noise pressure-flow curves for pore size distributions WITHOUT curve fitting or post-processing.
• Measurements are fast, sample preparation takes less than 30 seconds, and no mercury is involved.
• Over 1000 pts/experiment, 20 Hz internal data processing speed.

CUT COSTS WITH SMART GAS SELECTION

• AccuPore uses a compressor for low-pressure operations (bubble point measurement and large pores) and switches to high-pressure bottled gas for analysis of small pores. This reduces the need for expensive high pressure gas, lowering recurring costs.

EXCLUSIVE PRESSURE RAMP AND STEP CAPABILITY

• SmartFlow system guarantees the most precise pressure control, highest sensitivity, and highest signal to noise.
• PRESSURE RAMP: Increasing pressure at a steady rate shortens measurement time, provides a highly repeatable measurement, and produces data points tightly spaced in pressure.
• PRESSURE STEP: Pausing at each pressure for equilibration allows all pores of a given diameter to fully empty before moving to the next pressure, regardless of pore length or tortuosity.

ULTIMATE SAMPLE SIZE FLEXIBILITY

• Sample diameters: 13 mm, 25, mm, 47 mm all within the same sample chamber. A selection of sample supports provide reliable measurements to the highest pressures, even for thin or weak membranes while also reducing gas consumption by up to 95%.

WETTING FLUIDS

• Meet analytical challenges of new material characterisation and support requirements of legacy methods, eg Galwik has low surface energy and vapor pressure: filling pores completely and resisting evaporation during analysis. Porewik is also available for legacy method compatibility and specific demanding applications.

INTUITIVE INTERFACE & MICROACTIVE SOFTWARE

• Built-in Breeze touchscreen UI with full standalone instrument control and data analysis.
• Remote PC control and data analysis over network connection.
• Advanced analysis and reporting, coplot with complementary porosity data

Applications

BATTERY AND FUEL CELL SEPARATORS AND MEMBRANES
Optimise 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.

FILTRATION
Predict and ensure size-based selectivity and mass-transfer rate by optimizing the number and size of pores.

NON-WOVENS
Often characterised 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.

METAL AND CERAMICS
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.
