Company Profile

DESAGA, a German company, is dedicated to the research of thin layer chromatography technology and the development and manufacturing of thin layer chromatography analysis instruments. In the 1950s, it produced the world's leading thin layer chromatography scanner, making important contributions to the development of thin layer chromatography technology. With decades of experience accumulation, it was acquired by Biostep in Germany in 2011 and invested more funds and technology in product upgrades and innovations. The performance and progressiveness technology of the instrument have always been in the forefront of the world.

Biostep's products include a full range of instruments for thin-layer chromatography and gel detection. From sampling, development, impregnation, scanning analysis, to atlas photography and quantitative analysis of images, there are a variety of models to choose from, such as scanner, spotter, development instrument, spray, atlas observation and imaging system, electrophoresis instrument, etc.

Instrument Introduction:

It is composed of specially designed light source system, high-performance digital camera and software control system, which can take pictures of thin-layer chromatography or gel electrophoresis with true color fidelity and ultra-low detection limit, obtain fingerprint information of the atlas, and record, save and standardize management;

The software system provides data collection, automatic calculation of Rf value, text annotation and editing of images, spot comparison and enlargement, saving, displaying, printing, etc;

Software controls imaging operations, and all raw data such as shooting conditions and parameters are recorded in real-time, traceable, fully compliant with GMP/GLP standards and 21CFR Part 11 specifications, and capable of IQ/OQ verification;

Text and labels can be added to the photos taken, allowing for arbitrary selection of font and font size, display in any proportion, and overlay comparison;

Each photo is automatically labeled with a work diary such as date, experimenter, unique serial number, and can be password protected;

Light source system: Built in 254nm/366nm ultraviolet and white light tubes, patented layout design to ensure uniform illumination and completely eliminate the interference of stray light.

Main applications:

• Biochemical analysis such as gel electrophoresis, electrofocusing protein and nucleic acid research

Chinese medicinal herbs, decoction pieces, formula preparations, single ingredient preparations

• Cosmetics

• Food
