Cary Eclipse Fluorescence
Spectrophotometer

  • Equipped with an unique patented Xe-Flash lamp module
  • Fast scanning monochromators - maximum scan rate of 24,000 nanometers (nm) per minute
  • Data collection rate of 80 points per second
  • Due to 80 Hz flash of lamp, measurements can be taken every 12.5 ms

 

  • Four collection modes: Fluorescence, phosphorescence, chemi/bio-luminescence, and time resolved phosphorescence
  • Fast kinetics: scans at 24,000 nm/min without peak shifts using Xenon flash lamp technology and up to 80 points per second in steady-state fluorescence mode
  • High sensitivity: red-sensitive photomultiplier tube detectors extend to 900 nm

 

 

Additional instrumentation being utilized by the Pavel Research Group:

AA ICP
Varian Atomic Absorption Spectrometer

Varian Inductively Coupled Plasma - Optical Emission Spectrometer (ICP-OES)
   
AA ICP
Micromeritics Surface and Porosity Analyzer

CEM Explorer Hybrid 12 Microwave
   
AA
Tangential Flow Ultrafiltration System

   

Students in thePavel Research Group also have access to some of the instrumentation in the Microscopy Center which is part of the Wright State University Boonshoft School of Medicine.

Due to the kindness of my collaborator at the WPAFB, Dr. Daniel Felker, our group could utilize free of charge a scanning electron microscope (SEM) microscope with Energy Dispersive Spectrometry capabilities (EDS), model EVO LS 10 Series from Zeiss Inc. Key features include class leading X-ray geometry, class leading secondary electron imaging in variable pressure, high brightness LaB6 source option, clean pumping technology with fast pump down, and high repeatability stage with large stage movements. The EVO LS 10 microscope is an environmental SEM providing the capability to prevent dehydration artefacts in the microscopy of life science specimens.

Chemical fume hoods, an analytical balance, a 40-220 rpm clinical rotator, an accuSpin Micro 17 ventilated microcentrifuge with 24-place rotor, basic ceramic stirring hotplates, a 500 series economy lab oven, a vortex mixer-pulsing,a water-bath, and so on.
