The Horiba FluoroMax 4P fluorometer allows emission and excitation spectra from 250-850 nm. The auto polarizers make it a routine instrument for fluorescence anisotropy measurements and kinetic studies where dye binding processes take place. Operating on top of Origin brand software, data fitting and export options are fairly comprehensive.

Mettler Toledo DMA 1 system is a 10N maximum environmental DMA capable of both strain and stress controlled sinusoidal loading. Conventional thermal-mechanical DMA and static mechanical testing can be done in atmospheric conditions from 25 to 600 degrees C. Submersion testing can be performed in a variety of solvent systems with bath controlled heating and cooling from -5 to 80 degrees C. Crash cooling liquid nitrogen allows the system to perform testing down to -190 degrees C.

The PicoQuant FluoTime 100 time correlated single photon counting (TCSPC) system has excitation options from 390 to 640 nm using a combination of pulsed diode sources (pulses ~90 ps) and nanosecond LEDs (pulse ~350 ps). The operating frequencies are 40, 20, 10, 5 and 2.5 MHz, allowing decay windows of 25, 50, 100, 200 and 400 ns respectively. Collection is filter based and can be customized to collect from 420 to 800+ nm. Additionally, the system is outfitted with emission and excitation polarizers, allowing for emission anisotropy decay measurements.

The Olympus IX-70 inverted fluorescence microscope, with a cooled high-sensitivity CCD, is outfitted to provide transmission, bright field, phase contrast, polarization contrast and fluorescence imaging from excitations of 350 to 650 nm and collection from 380 to 700 nm. With the system we have a library of filter and dichroic mirror optics for the generation of customized filter cubes for almost any combination of wavelength needs.

The Shimadzu UV-2550, with it’s double-blazed grating, double monochomator design, provides a high-energy throughput optical system with ultra-low stray light. While featuring low stray light, excellent energy characteristics are provided over an extremely wide wavelength range (200 – 1100 nm), from the ultraviolet to visible, and into the near infrared for both liquid and solid samples.

The Olympus FV 1000 confocal platform allows for full spectral imaging with a variety of excitation options: 405 nm, 454 nm, 488 nm, 515 nm, 543 nm and 635 nm. Single pass three channel imaging is routine on this system, with two of the detectors being monochromator based and one being filter based. Both 405 nm and 640 nm pulsed laser sources allow for fluorescence lifetime imaging microscopy (FLIM) on the FV 1000 platform using a PicoQuant TCSPC FLIM add-on. Two detectors allow for two color FLIM or for anisotropy decay imaging (A-FLIM).

The Xtreme system combines high-sensitivity optical and radiographic molecular imaging (Biolumenescence and Fluorescence) with high-resolution digital X-ray to deliver precise anatomical localization of molecular and cellular biomarkers in vivo. Magnified X-ray capabilities allow for X-ray imaging of small species such as zebrafish with high resolution and contrast. Software automation simplifies complex multimodal imaging protocols. The system includes animal handling features such as a heated sample shelf, a gas anesthesia system and a MARS 360-degree animal rotation system. 

The Malvern Zetasizer Nano ZS uses photon correlation spectroscopy (PCS), which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid, for size analysis measurements and electrophoretic light scattering (ELS), which determines electrophoretic movement of charged particles under an applied electric field from the Doppler shift of scattered light, for zeta potential determination.
