Used HITACHI U-4100 #293602269 for sale

HITACHI U-4100 spectrophotometer is a powerful and versatile tool for various laboratory tasks, capable of delivering highly accurate results. It is a double-beam spectrophotometer that can simultaneously measure both transmittance and absorbance. It achieves this with a light source, a sample compartment, and a detector. The sample compartment allows for a wide range of sample shapes and sizes, and is also able to maintain temperature for samples such as dyes, that may require a consistent temperature for highly accurate results. It can measure samples up to 90mm in diameter and 4mm in width. The light source consists of two sets of lamps, an interference filter, and an imaging device which work together to deliver extremely precise readings. The interference filter lets only a single wavelength of light through, while the imaging device collects light and directs it towards the detector. The detector is made up of a set of photoelectric cells, tuned to measure a single wavelength of light. The detector is connected to a preamplifier which amplifies the signal sent by the cells and sends this signal to the control unit. The control unit is the brain of the spectrophotometer and is responsible for controlling the movement of the lamp, light source, and sample compartment, wavelength selection and setting, storage and retrieval of data, communications with software, and displaying results. Overall, HITACHI U4100 spectrophotometer is a powerful, precise, and versatile tool for laboratory applications. It's ability to measure both transmittance and absorbance simultaneously, as well as its ability to control and measure a wide range of samples makes it ideal for many lab applications.
