Ambala, in Haryana, is widely regarded as India’s largest cluster for scientific instruments and laboratory glassware. For decades the city has supplied schools, universities and industry with lab apparatus, and a large share of the country’s educational glassware is made and finished here. Buying from a manufacturer in Ambala means you skip layers of middlemen — getting lab-grade glassware at the price the rest of the market buys it for.
