sesam lab new


The School has three units supporting the function of the Instruction and Research Divisions, namely: the information systems and publications, the environmental laboratory and the environmental simulation and modeling laboratory. 

Under the information systems and publication unit are the audiovisual facilities, the library and the Journal of Environmental Science and Management (JESAM).  These units provide students and researchers the facilities they need for their research activities and for presentation and dissemination of student, faculty and staff research outputs.

The environmental laboratory is designed for research and teaching purposes. Currently, it is capable of doing on-site water and air quality testing. It is also used for sample preparation, such as blending, crushing, mixing, drying and ashing. Available facilities/equipment in the laboratory include: 

Sound Meter (2 units)

Air Sampler

Drying Oven

Analytical Balance

Orbital Shaker

Magnetic Stirrer


Muffle Furnace

Water Sampler (2 units)


Mini Sound Meter

Turbidimeter with pH and Temp Meter

GPS (6 units)

Type AA Water Current Meter

DO meter


Stereomicroscope (2 units)

Digital compact camera for underwater transect work

Gel electrophoresis (stationed at the Inst. Of BioSci)

Scuba gear/equipment

Several new equipment are currently being acquired and are expected to be delivered within the year. These include:

Portable XRF


Petrographic microscope

Ambient air quality analyzer

Water quality multi-parameter meter

Heavy metal analyzer (water)


Digital Thermohygrometer

Haga Altimeter

Soil nutrient tester

Digital soil pH

Digital caliper

Portable balance

Plankton net

Sediment grab

Secchi disk

Most of these new instruments are designed to support the plan to develop a mobile laboratory that can function as a quick-response mechanism for environmental concerns. As such equipment for soil, water, rock and air quality analyses were requested in their most portable forms.

The environmental simulation and modeling laboratory houses the computers designated for student use.  These computers are connected to the internet and are loaded with licensed software that includes Statistical Package for the Social Sciences (SPSS), ARCGIS, IDRISI and STELLA, that can be utilized for simulation and modeling, spatial and temporal analysis and for optimization and environmental risk analysis.

Because of the multi-institutional nature of SESAM’s setup, students and researchers that require specialized laboratories or equipment are provided access to the different laboratories within the campus through the School’s affiliate faculty members. These include laboratories at the National Institute of Molecular Biology and Biotechnology (BIOTECH), Institute of Chemistry, Institute of Plant Breeding and GIS Laboratory of College of Forestry and Natural Resources (mostly computers with licensed GIS and modeling software).
