The PB Membrane Pore Size Analyzer utilizes the gas-liquid or liquid liquid displacement method (bubble pressure method) to accurately measure the pore size characteristics of membrane materials. By applying a pressure difference across the membrane, the system overcomes the surface tension of the infiltration liquid, driving it through the pores to determine pore throat sizes. This method is the standard for ASTM thin film pore size testing.
The analyzer is widely used for pore size analysis in materials such as filter membranes, fiber membranes, filter elements, battery separators, fabrics, non-woven fabrics, paper, ceramics, sintered metals, rocks, concrete, and more.
The VD 12 is a high-performance vacuum degassing system featuring two independent stations with 12 total positions for simultaneous degassing of different sample types. It offers precise temperature control, with a standard setting of 400°C and an accuracy of ±0.1°C, and a user-friendly 32-segment programmable touch-screen controller for easy operation.
The system includes both **air-cooled and water-cooled positions** for optimal temperature regulation and utilizes **automatic pressure-controlled pumping** to ensure efficient high-vacuum degassing without sample loss. A built-in pressure sensor monitors degassing completion.
An optional cold trap protects both sensitive samples (e.g., MOF, COF) and the vacuum system from contamination by organic reagents. The AD 12 is ideal for precise, simultaneous degassing of multiple samples.
The BSD-TD Automatic True Density & Porosity Analyzer is a highly precise instrument designed for measuring true density, open porosity, and closed porosity of a wide range of solid samples. With an accuracy of better than ±0.03% and a repeatability of better than ±0.015%, it provides reliable and precise results, with a resolution of 0.0001 g/ml. The analyzer offers fast testing, completing a single station test in just 0.5 to 1 minute, and doubles its efficiency with two analysis stations.
Suitable for a variety of sample types—such as powders, granules, blocks, foams, slurries, and non-volatile liquids—the BSD-TD’s test method utilizes a high-volume, direct-sample test cavity, enhancing accuracy by optimizing sample volume utilization. The “bottom-loading bayonet-type” sample pool accommodates larger samples, further improving test precision. Additionally, the system features a fully automatic constant temperature mode with a temperature accuracy error of less than 0.1°C, ensuring consistent environmental conditions for accurate results.
The BSD PH High-Pressure Adsorption Analyzer is a fully automated, high-efficiency instrument designed for high pressure gas adsorption analysis. With a pressure range of 0-50/69 MPa and a temperature range from -196°C to 1100°C, it provides precise and versatile testing capabilities for a wide array of materials. This instrument offers seamless operation and reliable data, making it an ideal solution for advanced adsorption studies in both research and industrial applications.
