The Hitachi F-2700/F-2710 Fluorescence Spectrophotometers are available in two configurations depending on your laboratory's needs. The F-2700 can be used as stand-alone and also PC-controlled; the F-2710 is a PC-controlled-only model.
Model F-2700 Stand-Alone System
(PC control optional)
Model F-2710 PC-Control System
The large built-in keyboard and LCD screen
make operation a breeze.
The F-2700 in stand-alone configuration using the built-in keyboard and LCD screen is ideal for teaching and routine measurements. Adding PC control expands its capabilities to biotech research and quantum yield applications.
The F-2700/F-2710 feature an excellent signal-to-noise ratio (800 S/N RMS, Raman band of water at 5 nm bandwidth). With PC control the scan speed is as high as 12,000nm/min, making it ideal for 3-D scan measurements. A wide array of accessories is available, including automatic sampling, quantum yield measurement, full-range spectral correction, and 100µL micro cell.

Hitachi's unique concave diffraction gratings combined with a low noise detection system result in an excellent signal-to-noise ratio (S/N ≥ 800 RMS, Raman band of water using 5nm slits), allowing measurement of fluorescein with sensitivity in the order of 1 x 10-12 mol/l.
Hitachi fluorescence spectrophotometers offer a wide dynamic range of 6 or more orders of magnitude. This is the result from our unique circuit-processing technology where our fluorescence spectrophotometers switch gain automatically and allow measuring samples with low and high fluorescence intensity under the same conditions. This eliminates the need to prepare multiple calibration curves for a range of concentrations.

The Hitachi F-2700/F-2710 fluorescence spectrophotometers's variable slit width works well for samples displaying sharp peaks or for samples with broad band peaks.

The F-2700/F-2710 Fluorescence Spectrophotometers offer optional accessories for performing full range spectral correction for both the Excitation and Emission monochromators. This allows eliminating spectral distortions in your data resulting from the variation in power distribution from lamp to lamp, efficiency curves of the diffraction gratings and sensitivity of the detector. This is a desirable feature when publishing data or when comparing data from instrument to instrument. The picture below shows a measurement for NIST SRM 936.

This add-on software package to FL Solutions is a powerful application which allow you to design your own reports by arranging and selecting items from included templates. For advanced users familiar with macros, it allows performing customized calculations and reports using data obtained by the instrument, such as the example shown to the left for calculating chromaticity.
Allows measuring samples at controlled temperature between 5 and 60°C. Stirring is available for added temperature uniformity within the sample. Stirring speed is indenpendently adjustable from the front panel, between 500 and 1200 rpm. A dry air port is available to eliminate condensation when measuring below ambient temperature. (Requires a heated water circulator)
Used for thermostatting samples at a fixed or programmable variable temperature in the range of 0 to 100°C (in steps of 0.1°C). Temperature is controlled by a Peltier device for fast heating of the sample. Temperature accuracy is ±2°C. Requires an ambient water circulator for cooling. Includes a dry port to control condensation. A cell cap is included to avoid evaporation when working at temperatures above ambient.
Includes a single temperature controller with a range of -10.00 to +105.00°C (±0.02°C). The lower limit could be extended down to about -40°C by ordering p/n AN0-9357 Windowed Jacket and Cap.
Dry gas purge may be used to reduce condensation when working at low temperature. It includes an ambient water circulator, required for removing heat from the Peltier during the cooling cycle. Includes SER 2.X Serial Interface, signal cable and computer program for external PC control which adds temperature ramping capability. Includes built-in filter holders.

Used for measuring fluorescence or phosphorescence of solutions frozen to a liquid nitrogen temperature of -196°C (77°K). It replaces the standard sample compartment. Includes a built-in filter holder, liquid nitrogen dewar flask and four quartz sample tubes (two 5mm and two 8mm diameter tubes).
NOTE: The sovent used must be water-free. EPA (ethyl-ether, iso-pentane, ethanol=5:5:2) is recommended.
Accomodates four 10mm square cells (not included) and replaces the standard sample compartment. The cell position is selected by a control at the front of the sample compartment.
Accomodates eight 10mm square cells, or 10mm and 12mm OD test tubes that are less than 105mm tall (not included). It replaces the standard sample compartment. Cell position is selected by control at the front of the sample compartment.
Allow measuring transmisson data for a sample and blank. Using built-in data processing functions in FL Solutions, it calculates percent transmission (%T) of the sample. This data is exported to Excel to calculate absorbance. It is useful for determination of Relative Quantum Efficiency of liquid samples.
Utilizes concave mirrors positioned immediately behind the excitation and emission beam paths to improve sensitivity by 2X. Accomodates a 10mm square cell (not included) and is mounted on the base of the standard sample compartment.
For measuring solid samples up to 30mm thick such as plastic, paper, cloth, thin films, fibers, powders and highly concentrated solutions in a cuvette. Front face geometry is used with the excitation light beam incident to the sample at a 30 degree angle. This geometry eliminates the entrance of excitation reflected light into the detector. Includes one non-thermostatted powder holder which is mounted on the base of the standard sample compartment.
Neutral density screens which pass all wavelengths from 200 to 900 nm. The set consists of one each 4%, 8%, 11%, 15%, 23% and 33%T screens. A filter holder is included. NOTE: Neutral density screens reduce the excitation light when narrow slits are not available. In a variable band pass instrument, screens are useful for adjusting the relative intensity to a desirable Y-scale position for a set of samples. Decreasing the slit width however results in a higher reduction in intensity than the addition of a screen.
