Used PERKIN ELMER 785A #9108782 for sale

PERKIN ELMER 785A is a double-beam, scanning spectrophotometer that is capable of providing precise and reliable spectrophotometric measurements. The instrument is designed to quickly measure a broad range of photometric parameters, including absorbance, percentage transmission, and absorption coefficients. 785A features two light sources, one in the form of a tungsten-halogen lamp, and the other an deuterium lamp. The two light sources produce broadband and continuous UV-VIS light, a combination which provides superior capabilities for measuring light absorption. The broad measuring range provided by the two sources allows the unit to detect light absorption over a wide range, from 203 nm to 1100 nm. The integrated light sources are temperature-controlled to maintain a stable output, ensuring accurate and reliable results. The instrument can measure in both absolute and comparative modes. In absolute mode, the instrument compares the intensity of a wavelength of light to a reference point, while in comparative mode the instrument compares changes in absorbance at two different wavelengths. This versatility allows the user the flexibility to carry out a wide range of tests. PERKIN ELMER 785A has a built-in sample compartment, making it easy to insert and remove test cuvettes. The unit also features an automated cuvette holder, allowing the user to easily position up to 8 cuvettes for rapid testing without the need for manual loading. This makes it ideal for high-throughput applications in research and development. The unit is controlled by a computer-based user interface, compatible with a wide range of operating systems. The user-friendly control panel allows easy access to the instrument settings, including selections for wavelength, light intensity, and scan rate. Additionally, the data display features a variety of graphs and tables to provide users with a clear view of the results. A selection of optional accessories are available for 785A, including a set of optical filters for use in applications requiring instrument testing at a specific wavelength, as well as an automated injector for high-throughput testing. The instrument also comes with replaceable parts for extended use. The overall design and construction of the unit is sturdy and durable, making it well-suited for industrial and laboratory environments.
