QE-PRO scientific grade spectrometers
Product description
The QE-PRO scientific grade spectrometer is especially well suited for low light level and advanced measurements, such as absorbance, reflectance, Raman spectroscopy, DNA sequencing and fluorescence. A 15,000 spectra buffer ensures data integrity at high collection rates and an advanced optical design and thermoelectric cooler combine to provide thermal stability over long-term measurements. Whether for high speed or wide concentration range measurements, the QE-PRO brings exceptional performance to your lab or process application. Buffering enables full-spectrum kinetics measurements to be performed every 8 milliseconds or 125 measurements per second.
