The SABS tests everything from disposable nappies (diapers) to sardines at its facility in the country's capital, Pretoria. The building itself is a maze of hallways and laboratories, decked out with all the trappings of science - white coats, glass instrument cases, beakers and microscopes.
Outside, past the expansive gardens, next to a heap of discarded equipment, lies the institution's condom testing lab - and Isabella Masemola.
