The QuantaMaster range of bench-top fluorometers offers chemists, biochemists and physicists such a wide choice of different configurations, that it is possible to match individual requirements - exactly.
Renown for their high sensitivity:
- Standard bench-top instrument 3000 : 1 S/N
- Research grade spectrometer 6000 : 1 S/N
(measured as signal/noise for the 397 nm water Raman peak)
and interchangeable modules and attachments:
- Stop flow attachment
- Polarizers
- Temperature module
- Flash lamps
- Titration
- Microscopy and Imaging
QuantaMaster™ offers a formidable choice in R&D, QC and teaching applications.
Filter Based Systems (Model QM-2/2005)
Filter-based systems are used when there is a need for ultimate sensitivity, but without wavelength scanning capabilities. Desired wavelengths are selected by using the appropriate bandpass filters. Excitation is provided by our patented high-intensity Xenon arc lamp (mercury, deuterium and tungsten lamps are also possible). Over 65% of the light from the lamp is collected and focused forward to the sample, making this far superior to conventional high wattage light sources!
Monochomator Systems (Model QM-4/2005)
The addition of f4 Czerny-Turner monochromators will provide you with computer-controlled scanning capabilities, allowing the instrument to be tuned for individual wavelengths.
Scanning of either excitation or emission wavelengths increases the capabilities for characterisation of spectral probes. In addition, you can set and control both excitation and emission bandwidths, which is essential for the resolution of complex or hyper-fine spectra.
And finally, since the monochromators can be programmed to move rapidly back and forth between wavelengths, multiple dye experiments can be performed routinely on a single sample.
Dual Emission Systems (QM-6/2005)
Adding a second detection PMT and monochromator converts the system to high speed multi-channel emission detection. Emission scanning, ratiometric analysis and polarisation (anisotropy) from 200 nm to 850 nm are some of the experiments that can be carried out. Additional gratings and detectors are available to extend this range to 2000 nm, giving high quality infrared detection.
RTC QuantaMaster™ (Model QM-7/2005)
Rapid Temperature Control System
Peltier-controlled cuvette holder
Fast temperature ramping and the ability to study fluorescence as a function of accurate sample temperature is opening up new areas of research. This version of the QuantaMaster™ is equipped with a Peltier controller, providing accurate temperature control from 0oC to 80oC.
Temperature ramps up to 20 degrees per minute, isothermal presets and temperature cycles are all under complete software control. Now protein unfolding, lipid melts and temperature-dependent polarizations are a breeze.
