Florescence Spectrophotometer

● Measurements mode & Applications: Fluorescence, phosphorescence, chemiluminescence, and bioluminescence - Excitation, emission, constant wavelength synchronous, and constant energy synchronous spectral scanning;3D excitation/emission scans, 3D synchronous and kinetic scans, Chopper or suitable mechanism should be offered to block the beam when measuring luminescence or phosphorescence. Single or multiple wavelength kinetics along with Below Typical performance - Light Source: Xenon lamp 150 W or better - Monochromator: Czerny-Turner/ modified Rowland monochromator - Grating: Excitation: min.1200 lines/mm or better, Detectors: High performance room temperature PMT detector. The spectrometer should be equipped with a reference photodiode or PMT to monitor excitation lamp intensity fluctuations or reference signals. Spectral bandwidth :1.5 to 20 nm or better (continuously variable and computer controlled) Wavelength range: Excitation range (200 to 850 nm or better) & Emission range (200 to 850 nm or better) Wavelength accuracy: 1-1.5 nm or better Wavelength Repeatability: ± 0.2 or better Typical Signal to noise ratio: > 750:1 RMS sensitivity @ 350 nm excitation, excitation and emission slits 10 nm, 1 s Signal Averaging time Resolution :1.5-2 nm or better, Wavelength scan speed :> 24000 nm/min, or better, Certification: CE, Sample compartment and measurement modes: a) Sample compartment should be suitable for analyzing liquid (Right angle) and solid samples. b) A solid sample holder for recording the emission of powder and thin films samples should be provided. Software should be User friendly, original licensed Windows based operating software in the form of CD ROM/ flash drive, it should have built in features like have facility for scan application, kinetics. The software should be able to automatically collect a series of excitation, emission, or synchronous scans in all x modes. The 3-D data can be sliced to produce single excitation or emission scans, or contour plots can be created to show the number of emitting species. Upgradations: System must be upgradable Microplate Reader Accessory, fiber optics probe & Stop Flow accessories etc. Warranty: Two years including PC for the instrument and 10 years warranty for the Xenon Source Accessories: • Cuvette pairs 3.5 mL– 1No and 350 µL– 1 No should be provided. • Solid Sample Accessory: Should include dedicated attachment to hold Film Samples, Powder Samples and 10 mm Cuvettes. • Five Additional genuine License of fluorescence Software’s for students. • 96 well microplate reader (optional). • Suitable Factory configured PC. • Vendor or OEM shall have repair/ service Centre in India. • OEM/ vendor shall have demonstration facility/online support in India.
