  • The Oriental Science Apparatus Workshops is privileged to serve, since 1919, a spectrum of customers from varied fields. OSAW serves as a one stop shop for all your laboratory needs ranging from Schools, Colleges, Universities to Industries both in the domestic and international markets. We hope this website brings about for you savings of cost which the modern infotech sector brings in terms of communication cost, time and effort.
  • With the coming into force of the WTO regulations in 2005 the world is going to be integrated into one big market.
  • India has made a remarkable turnaround from a highly protected economy right upto 1991 with all the infrastructure and other core sectors being controlled by the Government and a licence being required for everything to a totally free market enterprise.
  • The government is fast losing its controls on all the sectors. In this new environment, we are not only looking for export opportunities but also invite collaborators for products which which they feel have a good market in this region.
  • Indian offers competent Engineers, Professionals, reasonable Land Prices, good Industrial Climate, Skilled Labour at salaries lower than than other countries – We invite proposals not only for Scientific but also Medical, Engineering, Industrial and other equipments.


  • We manufacture a wide range of equipments used by Primary School, Secondary Schools, Undergraduate to Postgraduate Institutions. OSAW also caters to the needs of Defence and Industry wherein development of tailor-made products are undertaken on order.
  • OSAW has undertaken many projects on turnkey basis in India and Abroad, these include, interaction with the teaching faculty for decisions of practical curriculum, deciding the list of equipments for their labs and their supply and installation. We have also indegenised various products for our leading laboratories, which led to the saving of a huge amount of foreign exchange.
  • OSAW employs about 250 personnel including a dedicated team of Scientists, Engineers, trained Technicians and Management professionals capable of designing new products and constantly upgrading the existing ones.
