Student He Zhao uses the Transmission Electron Microscope

Student He Zhao examines a sample of gold nanoparticles that were produced in the lab. He is operating a Transmission Electron Microscope (TEM) to provide high resolution images of these extremely small particles, used to determine size, shape, and process yields.

Kyanna Alleyne uses the Scanning Electron Microscope

Kyanna Alleyne is examining Amphipod mouth parts using a JEOL IT 100 Scanning Electron Microscope (SEM). An SEM can provide high resolution images of sample surfaces, and Kyanna is using this information to help classify organisms.

Students works with NMR instrument

Jeanette Minah (foreground) removing a sample from the 400MHz Bruker Nuclear Magnetic Resonance (NMR) instrument. Victor Schultz and Sarah Millman (background) are determining a molecular structure from a spectra generated by the NMR.


Student works with machine

Ross Kuskovsky injecting synthesized B-Lactam derivative into Buchi Sepacore Preparative Column, which collects fractions of individual compounds by detecting UV activity or changing refractive index. The separation is dynamically monitored by computer.


Students work with incubator-shaker

Donald Lee and Daniel Catt growing E. coli cell cultures to produce aspartate aminotransferase. The VWR Symphony 500IR Refrigerated Incubator-Shaker maintains warm growing temperatures and ensures plenty of oxygen is available for the growing bacteria.


Student and professor work with spectrometer

Dina Lloyd (left) and Tim Beck (right) reattaching the ion source of the 3200 Triple Quadrupole Mass Spectrometer (Q-trap) AB Sciex mass spectrometer. The Q-trap delivers high levels of sensitivity and robustness for even the most complex matrices.


Students work with spectrophotometer

Daniel Catt and Donald Lee measuring the rate of an enzyme-catalyzed reaction on the Shimadzu UV-2550 UV-Vis Spectrophotometer.
