Engineered with extra-thick glass walls and a wider diameter than standard test tubes, it provides superior resistance to thermal shock and mechanical stress.\n\nManufactured from premium Borosil 3.3 expansion borosilicate glass, this 38 ml boiling tube is specifically designed to handle intense, direct flame heating without cracking. Its 25 mm outer diameter and 150 mm length allow liquids room to boil vigorously without flash-boiling or spilling out. The tube features a smooth, rounded bottom for uniform heat dissipation, a reinforced beaded rim for structural durability against chipping, and crisp white ceramic branding for easy identification.\n\nThick Wall Heavy-Duty Glass: Constructed with extra wall thickness compared to standard test tubes to withstand thermal expansion and high mechanical impact.\n\nDirect Flame Heating Safe: High-grade 3.3 borosilicate glass offers exceptional resistance to high temperatures and rapid thermal shock.\n\nAnti-Spill Wide Diameter: 25 mm width provides ample surface area for violent boiling and heating of chemical solutions without flash spillage.\n\nReinforced Beaded Rim: Smooth, turned rim prevents chipping during handling, corking, or test tube rack placement.\n\nAutoclavable \u0026amp; Chemical-Resistant: Highly resistant to chemical attack by acids, bases, and organic solvents; fully safe for steam autoclave sterilization.\n\nPerfect for chemical heating, sample boiling, tissue digestion, high-temperature reactions, and educational science experiments. Borosil 9800 boiling tubes can be repeatedly steam-sterilized in an autoclave at 121°C without affecting structural integrity or glass clarity.","brand":"edumartstore","offers":[{"title":"Default Title","offer_id":47216817012924,"sku":"7","price":32.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/8566\/2908\/files\/download_ce2900af-54cb-4522-abbe-17e4bf61e754.jpg?v=1785470004","url":"https:\/\/www.edumartplus.com\/products\/borosil-25-times-150-text-mm-heavy-duty-glass-boiling-tube-38-text-ml-code-9800-high-thermal-shock-resistant-borosilicate-3-3-labware","provider":"edumartstore","version":"1.0","type":"link"}
