ADC Bioscientific, the preeminent manufacturer of instruments to monitor gases, plant biology, and soil CO2 flux.

For the investigation of plant physiology, ADC produces the most portable and user-friendly equipment on the market. The photosynthesis measurement systems – ranging from ultra-compact to sophisticated systems for comprehensive experiments – are invaluable tools for thousands of researchers worldwide. To accurately and non-destructively measure leaf area and associated parameters, ADC produces the most compact and portable commercially available device. ADC’s hand-held Chlorophyll Content Meter is a highly reliable and affordable instrument to non-destructively quantify chlorophyll. To allow plant stress to be investigated through chlorophyll fluorescence, ADC supplies a range of chlorophyll fluorometers – from compact hand-held devices to fluorometers that offer exceptional experimental control and more testing protocols than any other portable fluorometer.


ADC’s reputation for designing equipment with the user in mind is confirmed by its instruments for monitoring gases and soil respiration. With research increasingly focusing on rising levels of greenhouse gases, ADC has designed a range of gas analysers suitable for research on a multitude of life science issues. ADC also excels in its range of sophisticated instruments to assess sources of CO2. The portable Soil Respiration Systems include both intelligent systems that control environmental conditions and ultra-compact and affordable instruments weighing only 2kg. The new Automated soil CO2 Exchange system is for long-term, unattended monitoring of soil flux.

Quality and customer support

For over 40 years, ADC Bioscientific has lead the development of instruments to make your research evermore sophisticated. By collaborating with leading scientists, ADC Bioscientific continues to improve and expand its product range while setting new standards in portability and ease of use. Our equipment is designed for optimum performance, even in harsh environmental conditions. Furthermore, every instrument is subjected to ADC's rigorous quality testing to ensure that it facilitates your research for many years to come.
