Its offer covered a wide range of disciplines, from optics, physics and mathematics to geodesy, mineralogy, astronomy and surveyance. After 1864, José Grasselli continued to carry on the business independently at number 5, Calle Montera.

They also supplied scientific instruments to prominent institutions like Banco de España and the Royal Palace of Aranjuez.
