ASLheader

The ASL is under the extension function arm of the Institute of Chemistry. It is primarily a teaching and instructional laboratory of the Institute for the chemical instrumentation courses and other chemistry courses where instrumentation is a requirement. The ASL extends its analytical services to both government and private customers.

CITIZEN'S CHARTER
