Opened in 1991, the Murphy Science building houses the Departments of Biology and Chemistry. Within the building are faculty offices, three lecture rooms, four biology laboratories, three chemistry laboratories, and one physics laboratory. The biology laboratories include a general biology laboratory, anatomy & physiology laboratory, microbiology/genetics laboratory, and ecology laboratory. Each lecture room is equipped with a computer and projector system. The general biology laboratory and the anatomy & physiology laboratory have microscope camera systems for the projection of microscope slides and dissections. The department also houses an animal collection and a botanical collection from east Texas. The ecology lab contains extensive equipment for terrestrial and aquatic ecology research.
The chemistry laboratories include a general chemistry laboratory, organic chemistry laboratory, instrumental laboratory, and forensic/toxicology laboratory. In the instrumental laboratory, the students have access to a variety of Shimadzu instrumentation: UV-vis Spectrophotometer, Prestige FT-IR Spectrophotometer, Gas Chromatograph, High-Pressure Liquid Chromatograph, and a Gas-Chromatograph-Mass Spectrometer. Additionally, the Department purchased an Attenuated Total Reflectance (ATR) attachment for the Prestige FT-IR, which is commonplace for chemistry and forensic analysis.
