PicoTAS Transient Absorption Spectroscopy System

picoTAS Picosecond Transient Absorption Spectroscopy SystemPicoTAS is one of UNISOKU’s newest innovative product capable of measuring Picosecond to Millisecond Transient Absorption Spectrometer. It uses the Asynchronous Pump Light and Probe Light technique, combined with the Randomly Interleaved Pulse Train (RIPT) method. This is a new patented technology, which allows to seamlessly bridge the picosecond and nanosecond time ranges and eliminate the notorious 1 ns – 20 ns time gap in conventional TAS instruments.

Vacuum Free Cryostats for UV-VIS, Fluorescence and Circular Dichroism: USP-203 Series

Vacuum free cryostat for liquid samples

Vacuum free cryostat for liquid samples

USP-203 Series of products are stand-alone cryostats. Their light weight and compact footprint allows them to be placed inside most commercial UV-VIS, Fluorescence and CD Spectrometers with proper adaptation. This allows temperature controlled measurements of absorption, fluorescence, or circular dichroism spectra.
