| 1 | Providing and Fixing of UV-VIS dual beam Spectrophotometer (Benchtop) Hach `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 (UVVisible)/ Reference Cell ii. It is will have High resolution touchscreen user interface. The spectrophotometer must be capable of operating through computer also. iii. There will be 8-position cell changer with switchable turret iv. It will have onboard methods, reporting and data export v. It is capable of open-lid operation. vi. There will be room light resistance. 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 Photodiodes Display 7-inch colour touchscreen, high definition, 800 × 1280 pixels Photometric Accuracy Instrument ±0.002A at 0.5A ±0.004A at 1.0A ±0.008A at 2.0A Wavelength Accuracy ±0.5 nm Baseline Flatness ±0.002A Compartments 8-position cell changer (standard) Drift (At 500 nm after 1-hour warmup) (0.0005A/Hr Keypad Touchscreen Lamp Xenon Flash Lamp ()5 years typical, 3 years guaranteed) Noise (RMS at 500 nm 60 consecutive measurements) =0.00020A at 0A at 260 and 500 nm =0.00030A at 1A at 260 and 500 nm =0.00040A at 2A at 260 and 500 nm Optical Design Double Beam Photometric Display -3A to plus 5A Photometric Range –2A to plus 3.5A Photometric Repeatability ±0.001A at 1A measured at 1.0A at 546 nm Spectral Bandwidth 2 nm Stray 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, 1 nm, 2 nm, 5 nm Wavelength Range 190 nm – 1100 nm Wavelength Repeatability ( ±0.2 nm Wavelength Scan Speed Slow, medium, and fast - up to 1600 nm/min Computer operation: The spectrophotometer can be operated from compatible computer and software. Computer and operational software to run Spectrophotometer will be a part of the spectrophotometer. Connections Single USB-A supports flash memory devices for method and data storage Warranty 3 years Providing of reagents for 1 year atleast for Nitrate, Fluoride, Iron, Sulphate |
