INTRODUCTION - WHO ARE WE?

Fast-Est Instruments (FEI) is a developer and producer of original scientific instrumentation and solutions. We specialize primarily in gas exchange measurement and light exposure control instruments that are typically used in studying photosynthesis of whole plants or leaves. We believe that only when using intact plants or leaves is it possible to study the mechanisms and regulation of a system as complex as photosynthetic apparatus.

Our instruments are able to fully control environmental properties surrounding the plant or leaf during the experiment and precisely dose them. These properties include temperature, illumination, and gas concentrations (O₂, CO₂, H₂O etc). It is possible to introduce changes in any of these parameters in a fine manner while keeping the other parameters at a constant level. While making these changes, the response of the plant/leaf can be recorded precisely by detecting CO₂, O₂ or H₂O uptake or evolution. Correlation between the environmental parameters and the state of the photosynthesis apparatus can also be established by several optical measurements, such as chlorophyll fluorescence and leaf transmittance at several wavelengths (810, 950, 550, 520 nm) that our instruments perform. The instruments are fully computer-controlled and data analysis is performed automatically by the computer.

Being active scientists ourselves, we are well aware of the needs of a scientist and the requirements imposed upon scientific instrumentation. Our designs are based on decades of successful experience in developing instruments for photosynthesis research. We have been active users of our own instruments for many years. They have led us to a multitude of scientific discoveries.
