Ambala Cantt in Haryana has been the epicentre of Indian scientific apparatus manufacturing since the pre-independence era. With skilled glassblowers, optical pitch-polishing artisans, and high-temperature porcelain kilns, Ambala Science Market & Central Optical Works supplies over 500+ universities, NITs, IITs, and medical colleges directly from our 125 Lawrence Road facility.
Laboratory porcelain must withstand severe thermodynamic cycles without micro-crazing or structural fracture. Our porcelain labware uses crystalline kaolin enriched with 33.2% Al2O3, vitrified at 1380°C to achieve 0.00% water absorption. It resists boiling 20% HCl with weight loss < 0.08 mg/dm², ensuring non-contaminating gravimetric analysis.
Indian academic and governmental institutions (CSIR, ICMR, ICAR, DRDO, State Universities) can purchase our equipment seamlessly through GeM (Government e-Marketplace). We supply standard compliance dossiers, NABL-traceable calibration reports, and drop-tested export crating for nationwide delivery.
