Photosynthesis and Transpiration
Computer Controlled Gas Exchange Systems
A fully integrated lab-based system including analyzers for measuring CO2 exchange, O2 exchange, water vapour, flow rate, temperature and light intensity. These systems can be used with your own leaf chamber or Qubit's. A range of light sources are available. Choose from single channel or multichannel capability. Photosynthetic and transpirational parameters are calculated automatically.
Our inexpensive laboratory packages for plant CO2 and water vapour analysis are used in hundreds of universities and research institutes worldwide. A simple, but extremely accurate infrared CO2 analyzer is at the heart of these very popular systems. Can be combined with our Chlorophyll Fluorescence Package.
A unique instrument capable of measuring instantaneous gas phase O2 exchange from leaves. Use in combination with a CO2 analyzer for measurement of PQ and reductant flux. Measure O2 with an accuracy of 1ppm against an atmospheric O2 background.
Qubit Systems's package for measuring dissolved O2 has features included in no other polarographic O2 monitoring system. The O2 electrode within the water-jacketed cuvette may be used for measurements of O2 consumption (or production) by biological samples or enzymatic reactions. Various chamber volumes available from 0.2 mL to 50 mL. Can be combined with our Chlorophyll Fluorescence Package.
The potometer may be used independently or concurrently with Qubit's S161 Humidity & Ttemperature sensor to measure changes in plant transpiration rate as environmental and phsyiological conditions are altered.
Qubit Systems manufactures a range of accurate, low-cost Infrared CO2 Analyzers that have numerous biological and environmental monitoring applications. Use our CO2 analyzers to measure photosynthesis in plants, roots, soil samples, microorganism colonies, etc.
The analyzers are easy to use and are inexpensive enough for classroom applications, yet they have the accuracy and reliability required for many research purposes.
Qubit Systems' gas-phase O2 sensors provide accurate measurements of oxygen concentration from 0-100% with a resolution of 0.01% (100 ppm). The O2 sensors can be configured for use in open flow or stop flow (closed) gas exchange systems.
For experiments requiring greater accuracy, Qubit Systems manufactures the world's only patented Differential Oxygen Analyzer (DOX) with a resolution of ±0.1 Pa O2 against a background of air (20.9 kPa). This remarkable instrument represents an unprecedented advancement in respirometry and photosynthesis research.
