The RatioMaster isn't just an imaging system. It's not just a microscope photometry system, and it's not just a cuvette system. The sensitivity of the fluorescence instrument is the single most important specification that relates most directly to the applicability for intracellular ion studies. Virtually every ratio fluorescence application depends upon measuring a small change in the fluorescence intensity as the cell responds to a stimulant. High sensitivity also permits the use of smaller samples.
Sample size is especially important when dealing with living cells.
The RatioMaster has the highest sensitivity of any ratio fluorescence spectrometer. When you purchase an instrument from PTI, you get a lot more than just the instrument. You get over ten years of experience in using these instruments to make accurate measurements. Our Product Specialists are trained to assist you in making the most appropriate instrument choice for your application.
