ADC Bioscientific Ltd

50 Years of Service to Science (1969 to 2019)

Proudly celebrating 50 years of service to science, as the gold standard for plant, soil and environmental CO2/H2O flux analysis.

Who we are
ADC BioScientific Ltd. have been designing, building and supplying infrared gas analysers for the measurement of CO2 gas exchange, since 1969.
Our renowned, single channel infrared gas analysis (IRGA) technology is incorporated into devices used to measure the carbon cycle through the study of plant, soil and atmospheric gas exchange.
Many ‘firsts’ for the global plant physiology market have come out of Research and Development at ADC. We developed the first battery portable photosynthesis system, enabling experiments to move from the greenhouse to the field, in the natural environment. We also developed the first photosynthesis system to have microclimate control, which enabled researchers to probe the photosynthetic process in greater depth.

We continue to lead the market with innovative, research-led analysers for plant, soil and atmospheric research. We are passionate about transforming carbon cycle research with portable, accurate and adaptable instruments.
We are committed to quality across our products and services and our worldwide representatives offer local, customer support.
We listen and respond, forming close partnerships with research institutes and universities worldwide.

Our Aims

To design, manufacture and supply scientific devices that are:

Portable – compact, lightweight, robust and reliable

Intuitive, adaptable, easy to use

Cost effective – we will not be beaten on price

More Information

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 instruments weighing only 2kg. The new Automated Soil CO2 Exchange system is for long-term, unattended monitoring of soil flux. Sales, Support and Service Providing strong after sales support, wherever our customers are in the world, through our network of experienced customer support centres, and directly from our headquarters in the UK. We appoint experienced representatives throughout the world, who are trained to ensure that they can assist ADC BioScientific users with any specifications and make recommendations as to the most appropriate analyser for the application. These distributors are backed by our professional sales and marketing team, who provide application advice, continuous product training and technical assistance. The intuitive design of our analysers means that in-depth training is not normally necessary for their operation. When possible, ADC BioScientific and our support centres can organise courses for customers wishing a more detailed explanation and demonstration of our products. Our representatives and service engineers are able to give assistance after delivery, either on site or, if necessary, by return to their local office. Spare parts are readily available. Our informative, technical manuals and “quick start” guides are valued by ADC users. Corporate, Environmental and Social Responsibility ADC BioScientific Ltd. is committed to: Reducing our waste and carbon footprint across all areas of the company Collaborations with University Departments Offering apprenticeships in partnership with local colleges Supporting local and national charities with in-house fundraising and regular giving Supporting and sponsoring local and international scientific conferences and workshops Maintaining service support for at least 10 years after the supply of equipment Encouraging customer feedback on our products and services in order to address the requirements of scientists
