Used VARIAN 710-ES #9231269 for sale

VARIAN 710-ES is a high-performance, double-beam spectrometer suitable for both laboratory and field applications. It utilizes evanescent wave spectroscopy (EWS) to measure the refractive index of a sample, and provides both absolute and relative measurements. The spectrometer's high sensitivity is enabled by the application of a He-Ne laser as the light source. The spectrometer features an optical head consisting of a rectangular optical chamber containing two facing mirrors that are adjustable along two axes. Two mounting locations for samples and a light source are provided. The light source consists of a He-Ne laser providing 325 nanometer (nm) incident light, and a detector with photon counting capability. A 0.5-meter fiber-optic cable connects the optical head to the console housing where the supporting electronics are installed, which control the light level, the relative sample positions, and the collection of data. 710-ES spectrometer features a frequency range from 0.22 - 1.05 µm, a scan speed of 0.3 - 5 µm/min, a frequency accuracy of 0.1 MHz, a signal-to-noise ratio (SNR) of >30 dB, and an effective dynamic range of >100 dB. The instrument also includes an internal software which controls the scope of measurement and provides automatic wavelength calibration. Furthermore, VARIAN 710-ES spectrometer includes several available spectral measurement modes, such as absorbance, transmittance, reflectance, and polarized light. The spectrometer was built to be portable and is powered by a Li-ion battery. The instrument is also equipped with a USB port, an Ethernet port, a video port, and an RS-232 communications port for data collection and analysis. The instrument is robust and durable, withstanding temperatures ranging from -20 to +60 °C and relative humidity ranging from 0 to 95%. 710-ES spectrometer is an ideal tool for a variety of analytical applications, including absorption, emission, reflection, refraction, fluorescence, Newton ring, and angle-of-incidence measurements. It is suitable for applications in environmental science, biomedical research, materials science, clinical research, quality control, and even forensic analysis. This spectrometer provides a reliable, robust, and precise instrument for many scientific and industrial applications.
