`The Spectrophotometer will be dual beam (viz. UV Visible) operation and with the reference cell position for kinetics application. It will mandatorily have an 8- cell carousel. The spectrophotometer must have room light resistance, allowing lid-open operation for improved speed and convenience.The Spectrophotometer will have option of automated cell changers and cell holders, sipper, and fiber optic probes for measurements outside of the sample compartment. It must accommodate high throughput measurements and temperature control. The Spectrophotometer will have following features: i. Spectrophotometer will be Double Beam(UV Visible)/Reference Cell ii. It is will have High resolution touch screen user interface. The spectrophotometer must be capable of operating through computer also.iii. There will be 8-position cell changer with switch able turret iv. It will have onboard methods, reporting and data export v. It is capable of open-lidoperation.vi. There will be room lightresistance.vii. It will have sipper(optional)viii. It must have optional facility for 4-position cell changer (long path cells) and Peltier-thermostat single cell holder (20 °C - 60°C)Specifications:Detector Type Dual Silicon PhotodiodesDisplay 7-inch colour touch screen, high definition, 800 × 1280 pixelsPhotometric Accuracy Instrument ±0.002A at 0.5A±0.004A at1.0A±0.008A at2.0AWavelength Accuracy ±0.5 nm Baseline Flatness ±0.002ACompartments 8-position cell changer (standard)Drift (At 500 nm after 1-hour warm up) (0.0005A/Hr Keypad Touch screenLamp Xenon Flash Lamp ()5 years typical, 3 years guaranteed)Noise (RMS at 500 nm 60 consecutive easurements)=0.00020Aat0Aat260and500nm=0.00040Aat2Aat260and500nm Optical Design Double Beam Photometric Display -3A to plus 5A Photometric Range –2A to plus 3.5APhotometric Repeatability ±0.001A at 1A measured at 1.0A at 546 nm Spectral Bandwidth 2 nmStray Light ( 1.0%T 198 nm (KCl), (0.05%T at 220 nm (NaI), (0.03%T at 340 nm (NaNO2) Wavelength Data Interval 0.1 nm, 0.2 nm, 0.5 nm, 1nm, 2 nm, 5 nmWavelength Range 190 nm – 1100 nm Wavelength Repeatability ( ±0.2 nm Wavelength Scan Speed Slow, medium, and fast - up to 1600 nm/minComputer operation: The spectrophotometer can be operated from compatible computer and software.
