Instrumentation

Circular dichroism spectrophotometer suitable for studying chiral molecules. The system measures the difference in absorption of right circularly polarized light and left circularly polarized light. As an example of the usefulness of the technique - this allows the user to study…

UV/VIS spectrophotometer for turbid samples. Scatter does not matter to this spectrophotometer, one can avoid the conclusion of ‘apparent high absorption’. The DeSa suspension presentation cavity or DSPC acts as an integrating sphere and allows the scattered photons to reach the…

This EOS bridge system (Ultrafast Systems) utilizes the same femtosecond excitation source, and allows measurements up to 400 microseconds. Detection wavelengths: 350-900 nm. Instrument response time is 100 ps.

Bench-top fluorometer for steady state and lifetime measurements. Can measure solid and liquid samples and follow either the excitation or the emission.
Simple operation using the FluorEssence software.
