Beijing JWGB Instrument Co., Ltd., established in 2004, is a national high-tech enterprise that integrates research and development, manufacturing, sales, and services. It specializes in the research and manufacturing of powder material characterization equipment such as physical adsorption instruments. In the past two years, Jingwei Gaobo has expanded its capabilities by acquiring the USA company AMI Instruments and the German company RUBOLAB, allowing it to provide a complete set of solutions for any adsorption material characterization experiment.

Our main products include static specific surface area and pore size analyzers, dynamic specific surface area analyzers, steam adsorption instruments, competitive adsorption instruments, and true density meters.

Founded in 1984, Altamira Instruments is a manufacturer and supplier of chemisorption and physisorption instrumentation as well as bench-scale micro-reactor systems for industrial and research use.

AMI instruments have been installed at more than 300 locations around the world. Among these installations are leading national laboratories, influential academic catalyst research groups and major chemical research centers. Altamira Instruments is a company started by and is still staffed by catalysis people. We take pride in our ability to support the end-user with applications/methods development.

In 2019, JWGB Group (www.jwgb.net) acquired Altamira Instruments.

Rubolab GmbH, established in 2014, traces its roots to a laboratory at Bochum Ruhr University in Germany. The company focuses on the development and distribution of high-quality measuring instruments for adsorption and catalysis research.

With its distinctive patented technology, Magnetic Suspension Balance（MSB）technology, Rubolab GmbH has emerged as a pioneering enterprise in high-pressure adsorption instruments and thermogravimetric analyzers.

In 2020, JWGB Group (www.jwgb.net) acquired Rubolab GmbH.
