Used VARIAN SpectrAA 220Z #9280366 for sale

VARIAN SpectrAA 220Z spectrophotometer measures the amount of light absorbed by a sample, based on the wavelength of light. This type of device is used to measure the concentration of materials in a sample and to characterize chemical compounds and minerals. It can also be used to measure other properties such as refractive index or spectral optical density. SpectrAA 220Z uses a single-beam optical equipment, meaning that it has one beam of light that it uses for both light source and detector. This system is faster and more secure than systems with two separate light sources and detectors, as the same amount of energy is used for both the light source and detector. The spectrophotometer utilizes solid state detectors in its design, such as a photodiode detector, to measure the light intensity in the sample. This also helps to optimize the instrument's accuracy and precision. VARIAN SpectrAA 220Z is designed to be easy to use, with a simple and intuitive graphical user interface. The device offers a range of features that help users to get the best out of the device, such as a detector calibration curve and an auto sampling function. It also has advanced functions, such as an auto-correction feature, which helps to reduce measurement errors and reduce the amount of time taken for measurements. The device is also equipped with a stabilized tracking grating which helps to ensure repeatable results. The wavelength accuracy is guaranteed to be 0.2 nm and also has a spectral resolution of 0.2 nm. Other features include the ability to save and store data onto a PC, as well as the capability to integrate into an existing laboratory network unit. SpectrAA 220Z offers a wide range of sample configurations, including solid or liquid-in-glass, liquid or solid in cuvettes, and non-cuvette liquid/solid. It is a modular device, meaning that the sample well, detector, and light source can be embedded into a single machine, ensuring that the instrument is ready for immediate use. The instrument comes with a range of accessories, such as sample holders, probe holders, and software, all of which aid usage. In sum, VARIAN SpectrAA 220Z spectrophotometer provides researchers with an efficient tool to analyze chemical compounds and minerals accurately and quickly. Its single-beam tool, stable grating, and high accuracy and precision make the spectrophotometer a great choice for the lab. The device is also designed to be user-friendly and adapted to a wide range of sample configurations, making it extremely versatile.
