Qubit Systems Inc. was founded by university researchers in 1996. Our equipment is used in over 500 universities and colleges throughout the world for research & teaching and has garnered universal acclaim for superb quality at exceptional prices (testimonials). We are scientists who understand the needs of scientists. No matter what your requirements for instrumentation, please contact us. We are always happy to provide free advice and are able to manufacture custom instrumentation to your specifications.


Qubit’s new Breath Analysis systems are designed to measure both steady-state and dynamic changes in human metabolic rate under a variety of test conditions. VO2, VCO2, VO2max, RMR (Resting Metabolic Rate), RER (Respiratory Exchange Ratio) and a host of other physiological and pulmonary parameters may be measured. Inhaled and exhaled breath are analyzed by rapid response O2 and CO2 analyzers at a high rate to ensure that the entire breath wave form is displayed graphically in real time.






Qubit's FytoScope Growth Chambers represent a remarkable combination of an LED-based growth chamber and a measuring device. In contrast to conventional growth chambers, they can program temperature, illumination and humidity, and have many additional interesting and useful features. Various sizes are available (60, 80, 170, 280 and 1300L), with options for full chlorophyll fluorescence imaging, LED upgrades, Temperature upgrades and Gas Exchange Measurements.


Qubit Systems' Gas Mixing Systems can be used to mix gases together to provide just about any mixture that you require. The systems use Mass Flow Controllers, which are controlled by PC-based software to provide accurate gas flows as calculated in the software. Qubit's gas mixing software can mix gases automatically - just select the gas mixture you require and the total flow rate of the mixed gas; the software will do the rest. The software performs all of the calculations to generate the gas composition that you require.
