Rapid-Kinetics and Spectroscopy: Stopped-Flow; Fluorescence, Absorbance, Circular Dichroism, Anisotropy Spectrometry

The MOS-200 uses a Xe or Xe(Hg) 150 Watts light source attached to a manual monochromator on an optical bench.

The connection to the Bio-Logic Stopped-Flow is done through a fiber optic specially designed to match the Stopped-Flow cuvette dimensions.

The signal detection is performed by a photomultiplier directly mounted on the Stopped-Flow and connected to its control unit.

The photomultiplier can be attached at 180° of the light source or at 90° allowing absorbance or fluorescence measurements (both at the same time using an optional additional detection channel). For fluorescence measurements, standard filters can be installed in front the photomultiplier tube inside the holder.

The MOS-200/M has the simplicity of the MOS-200 and a motorized excitation monochromator for automatic spectral reconstruction

• Outstanding signal-to-noise ratio
• For fluorescence, light scattering, absorbance, circular dichroism and fluorescence anisotropy (Includes as standard a unique and very sensitive fluorescence anisotropy measurement mode: the EMFA® method)
• Steady state spectral recordings
• Single wavelength Fast-Kinetics recordings

The modularity of the MOS-450 spectrometer makes it economical : a minimum of components to be rearranged for different modes of detection, and expandable.

The MOS-450 spectrometer comes as two basic configurations :

• MOS-450/AF for absorbance and fluorescence modes. This includes a dual illumination monochromator and single-channel detection.
• MOS-450/AF-CD for absorbance, fluorescence, fluorescence anisotropy and circular dichroism modes. This includes the same hardware as the /AF version, with in addition : polarizing optics, photoelastic modulator and synchronous signal detection.

• 256 or 1024 pixels
• 200 to 1100 nm
• up to 1250 spectral/s
• True 100% duty cycle
• Kinetics and steady-state modes
• Absorbance, transmittance, and photon counting modes

Jasco CD link
For J-600, J-700 and J-800 series

We have designed in collaboration with Jasco a mechanical and optical adaptation between the Bio-Logic series of stopped-flow instruments and the Jasco CD spectrometers.

This creates a very efficient and performing instrument for fast kinectics CD recordings.

Features

• Supports SFM-20, SFM-300, SFM-400 instruments
• CD spectra may be recorded either by setting a standard cuvette in the stopped-flow head or by switching to the spectrometer built-in cuvette holder.
• Precise and reproducible optimization of the light transfer to the stopped-flow cuvette.
• Instant optical switch from the stopped-flow to the spectrometer cuvette without removing or misaligning the stopped-flow instrument.
• Two 90° ports on the stopped-flow for recordings of the fluorescence kinetics.
