Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 1090 Series II #109984 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 1090 Series II spectrophotometer is aphotometer capable of measuring light intensity and spectral transmittance in the UV-Vis wavelength range from 185- 1020 nm. This device has three primary components including a photomultiplier tube (PMT), a monochromator, and a sample holder to place the sample in the beam. The PMT detects low light signals coming from the sample being tested, while the monochromator is used to select the desired wavelength and ensure that the beam is as narrow as possible. HP 1090 Series II has a number of features that make it incredibly useful for scientific research. It can measure low sample concentrations of 1 ng/ml and the sample holder has an adjustable distance from the PMT so that it can be adjusted to the optimum focusing distance. This instrument also uses transimpedance amplifiers to amplify low light signals coming from the sample. AGILENT 1090 Series II also has an integral detector which helps deliver a repeatable, rapid response time for measurements. This helps to reduce drift and ensure the most precise readings and reliable results. The integral detector also adjusts to changing light conditions ensuring that the sample is always optimally illuminated. HEWLETT-PACKARD 1090 Series II has a high spectral resolution of 0.2 nm, which is well suited for applications such as in vivo fluorescence lifetime measurements, and is able to accurately measure absorbance and transmittance. This device is capable of measuring a range of light intensities, from 2 to 32,000 mW/cm2. Finally, 1090 Series II is capable of temperature control from -25 to 65°C so that it can be used in a variety of applications including multi-temperature experiments and thermal stability studies. Overall, KEYSIGHT 1090 Series II is an incredibly versatile and precise spectrophotometer for use in scientific and engineering research requiring precise measurements of light intensity, spectral transmittance, and wavelength. This device has a number of features such as transimpedance amplifiers and adjustable focusing range, temperature control and an integral detector, that make it perfect for a variety of applications requiring accurate readings in the UV-Vis spectrum.
