UV-Vis spectroscopy

Multimode Microplate Reader Perkin-Elmer ENSIGHT

Multimode plate reader equipped with a thermostated chamber for 96-well plates. Allows for automated measurement of  UV-Vis absorbance, luminescence, and fluorescence.

Agilent Cary Multicell Peltier UV-VIS

Agilent Cary Multicell Peltier spectrophotometer for the study of absorption in the UV-visible region of up to 8 samples simultaneously. The system irradiates and collects the light transmitted by optical fibers and allows the application of rapid and accurate temperature ramps using an air-cooled Peltier unit. The design is particularly useful in the study of formulations and drugs as a function of temperature.

Perkin-Elmer Lambda 900

UV/Vis/NIR Spectrophotometer with depolarizer/polarizer accessories for acquisition of standard absorption spectra, kinetic measurements and linear dichroism experiments. The instrument is equipped with a software-driven temperature probe and a fiber-optics accessory for experiments on non-conventional samples (i.e. water-air interface, nanofilms on quartz slides).

Shimadzu UV-1601 UV/Vis-spectrophotometer

The spectrophotometer Shimadzu UV-1601 incorporates all the fundamental performances and functions required in UV-Vis spectrophotometry. With this instrument it is possible to carry out measurement at a fixed wavelength as well as kinetics; Quantitation may be performed by the single-wavelength, 2-wavelength, 3-wavelength, or derivative method. The UV-1601 has high performance sealed optics, housed in an impact-resistant case, so high durability for most solvents.  

Features:

  •     double-beam;
  •     range measurements: 190- 1100 nm;
  •     spectral data is obtained at constant bandpass with resolution of less than 2nm;
  •     monochromator mounted onto a highly stable optical bench ensure integrity and trouble-free operation;
  •     automatic monitoring and adjustment for fluctuations in lamp output and system electronics;
  •      the blazed holographic grating with self-aligning, energy-optimizing deuterium and tungsten-halogen lamps enhances precision across the UV-VIS spectrum.

Raman spectroscopy

Alpha300 S (WITec) Confocal Raman Microscopy

Alpha300 S (WITec) is a microscope combining confocal microscopy, confocal Raman imaging and AFM in a single instrument. A Raman-AFM microscopy mode is available to combine powerful chemical imaging along with high-resolution nanoscale surface characterization of the samples. The imaging technique is non-destructive and suitable for a wide variety of materials. The excitation source for the Raman analysis is a tunable Ar ion laser (454-514 nm) coupled with an optical fiber.

Confocal Raman inViaTM QontorTM

inViaTM QontorTM microscope with 532 and 785 nm excitation, equipped with XYZ motorized stage, flexible arm and Raman imaging techniques. The microscope is equipped with the unique LiveTrackTM technology, which allows the focus of the sample in real time during the observation of the sample and the acquisition of Raman maps. Thanks to this technology, samples with non-uniform, curved or rough surfaces can be studied.

Jasco J-715 Circular Dichroism

Circular Dichroism measures the difference in absorption coefficients of an optically active sample for left and right circularly polarized light. It is the method of choice for the determination of conformational details, such as protein secondary and tertiary structure, to monitor folding or binding and to assess purity of optically active substances (polymers, pahrmaceuticals, etc..). A circulating bath temperature control is available.
