The MIP-3600 Mercury Intrusion Porosimeter is engineered to evaluate the porosity and pore size distribution of mesopore and macropore structures in solid materials. Utilizing mercury`s non-wetting property under precise external pressures, the device gauges pore sizes from 30 nm to 600 µm, offering insights into the material`s pore volume distribution. This instrument is adaptable with various configurations, providing single or dual analysis ports and variable operating pressure ranges. Designed to adhere to ISO 15901-1:2005 and GB/T 21650.1-2008 standards, it incorporates advanced gravity difference principles, enhancing the experimental process by ensuring high accuracy and reliability. Equipped with a robust vacuum system and a VMSC system, the MIP-3600 maintains a stringent mercury vapor protection protocol, safeguarding user health and ensuring precision.

The Micro-200 Series BET Surface Area and Porosity Analyzer is a specialized instrument designed for precise assessment of BET surface area, mesopore, and micropore sizes in powder materials. Utilizing the volumetric nitrogen adsorption principle, it features dual independent testing stations and two degassing units, combined in a compact setup. Capable of generating detailed data such as BET, Langmuir, and DR, among others, this series is segregated into models A, B, and C. Model C stands out with its high-sensitive pressure sensors and a turbo molecular pump achieving an ultimate pressure of 10-8 Pa, apt for meticulous analysis of microporous substances like molecular sieves and activated carbon. Its software offers intuitive control over data acquisition and analysis, supporting remote operations. With advanced features like a multi-channel vacuum system and real-time temperature monitoring, the analyzer offers exceptional testing reliability and accuracy across a wide range of parameters.

Mercury porosimetry is a method to measure the volume, pore size distribution and porosity of mesopore and macropore in solid materials. It is based on the non-wetting characteristic of mercury to general solids materials. Under the action of external pressure, mercury can enter the solid pores, the greater external pressure, the smaller pore size into which mercury can enter The order of mercury intrusion is first external then internal, first large pores then small pores. By measuring the volume of mercury injected under different pressures, the volume of the corresponding pore size can be known, further obtain the pore size distribution curve (the curve of the pore volume changing with the pore size, also known as porosity).
