Spectro-Fluorometer with Phosphorescence and Polariser

Model Name :

Spectrofluorometer FLS1000

Specification

• We need a minimum 1 mL (3 ml preferred) completely dissolved liquid sample/~100 mg of solid powder sample. For thin films and pellet samples kindly discuss with
• Absorbance (Optical Density) at the excitation wavelength of the sample should be around 1
• Samples should not be toxic or The same should be declared by the user while filling up the Sample Requisition Form.
• Excitation wavelength and Emission Wavelength region should be given if already

Single Cuvette Holder: Temperature adjustable by water/coolant circulation, fitted with integrated probe for sample temperature monitoring by spectrometer operating software. Filter slots provided for holding 50 mm square filters. This sample holder is included as part of the standard system.

Magnetic Stirrer: Magnetic Stirrer to be fitted to single cuvette holder or 3- position sample turret. The stirrer comprises three stirrer bars and a stand- alone stirrer controller.

Powders, Thin-Films and Solids

Front-Face Sample Holders: A range of single position front-face sample holders are available for powders, thin-films and solids. These include linear staged holders, rotational holders and clamps.

Temperature holder specs

TE Cooled Sample Holder Standard Range (-10°C – +105°C): Thermoelectrically cooled 4-window cuvette holder with controller that enables stable temperature control of samples from -10°C to +105°C (-10°C with dry gas flow, 5°C without gas flow). The temperature can be held constant with ±0.02°C precision and can be rapidly changed. A magnetic stirrer (without stirrer bars) is included.

Polarisation/Anisotropy Specs

Standard Range (220 nm – 900 nm): Glan Thompson polarising prism. Spectral range 220 nm – 900 nm. The polariser can be automatically moved into or out of the beam. The position is recognised by the computer and the polarisation angle is fully computer-controlled. Automated anisotropy measurements are possible if both excitation and emission polarisers are present.

Integrating sphere for Quantam yield measurements specs:

The integrating sphere is a demountable accessory for the measurement of fluorescence quantum yields. It is 120 mm in diameter and has an inner surface coated with BenFlect to enable efficient scattering of light over a wide wavelength range. With the integrating sphere, the measurement of fluorescence quantum yields by an absolute method, as well as reflection measurements, are possible on solutions, film and powder samples. Holders for both direct and indirect excitation is provided. Two cuvettes and two powder trays are supplied as part of the sphere accessory. Options for electroluminescence and temperature dependent quantum yield measurements are also available.

TCSPC Electronics specs

The TCC2 is an electronics module with USB interface, which incorporates all the electronic modules required for Time-Correlated Single Photon Counting (TCSPC) and Multi-Channel Scaling (MCS). This includes constant fraction discriminators, variable delays, time to amplitude converter and a large memory for multi-channel analysis.

TSCPC time range: 2.5 ns – 50 ms full scale, MCS time range: 10 ms – 200 s full scale

From 500 to 8,000 channels

Time resolution from 305 fs/channel with ultra-low time jitter of 20 ps
