Import Adapters — Buy in wholesale FOB from Supplier in India

Rama Scientific Glass industries manufactures laboratory adapters from borosilicate glass 3.3 at their facility in Ambala, Haryana, India. These precision connectors serve to join dispieces of glassware, tubing and equipment in experimental setups where chemical inertness and thermal shock resistance are essential. The borosilicate 3.3 composition, with approximately 80% silica and 13% boron oxide, provides low coefficient of thermal expansion (3.3 x 10^-6 K^-1) that distinguishes it from soda-lime alternatives.

The adapters are formed by precision glassblowing techniques, with ground and polished joints for leak-free seals. Standard joint configurations include taper joints (ST/NS sizes per DIN 12242), thread connections (GL threads), and hose connections for tubing attachment. Surface finish and concentricity of ground joints determine sealing performance. The material withstands typical laboratory temperature cycling from cryogenic conditions up to approximately 500 degrees Celsius for short durations, though working limits depend on joint geometry and thermal gradient. Chemical durability against acids, bases and organic solvents is superior to standard glass, though hot concentrated alkalis and hydrofluoric acid attack the surface.

These adapters find application in educational chemistry laboratories, analytical laboratories, pharmaceutical quality control, and research institutions running distillation, reflux, filtration and synthesis procedures. Buyers include universities, government research councils, private testing laboratories, and chemical manufacturing plants. The supplier notes ISO certification and mentions FOB shipping terms, though specific ISO standards, MOQ and lead time are not detailed in the source data. Importers should confirm joint size standards (DIN, ISO or US customary), packaging for international transit, and whether custom joint angles or special bore diameters are available.

Rama Scientific Glass industries is located at 59 Vikaspuri, near Sai Mandir Road, in the Industrial Area of Ambala, Haryana, India. The supplier carries a 'voyage' trust tier and 'organic' supplier tier designation, with a 0.00% response rate and zero average response hours currently recorded. The city of Ambala is historically significant as a manufacturing cluster for scientific and laboratory glassware in India, though this regional association does not confirm any particular scale or capability for this specific supplier.

The available profile does not state year of establishment, number of employees, annual production capacity, or specific export markets served. No client references, patent holdings, or detailed quality management certifications are disclosed. Buyers should verify the specific ISO standard held (likely ISO 9001:2015 for quality management), request factory audit reports, and confirm whether the supplier maintains in-house annealing ovens for stress relief and joint grinding equipment, or whether these processes are subcontracted. The address places this supplier in Ambala's institutional area, which hosts multiple competing glassware manufacturers.
