BET Surface Area Analyzer NBSA-100 measures specific surface area ≥ 0.0005 m²/g with pore sizes from 2 to 500 nm. It analyzes pore volume in the range of 0.35 nm to 2 nm. This unit uses the static volumetric principle for accurate adsorption/desorption isotherm testing. It allows two-sample testing and three-sample degassing simultaneously. Our surface area analyzer uses a durable 4L stainless steel inner Dewar bottle for long-term thermal stability.
