UV-VIS dual beam Spectrophotometer Make:- Thermo Fischer Scientific, Hach, Lovibond, WTW ( Xylem), ELICO 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 measurement and temperature control. The Spectrophotometer will have following features: i. Spectrophotometer will be Double Beam(UV- Visible)/ Reference Cell ii. It 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 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(200C- 600C).
