Heat-resistant and chemical-resistant glass laboratory equipment used in manufacturing R&D and quality control departments. Primarily borosilicate glass products including beakers, flasks, test tubes, measuring cylinders, pipettes, Buchner funnels, separatory funnels, and distillation apparatus. Used as solution preparation and reaction vessels for material analysis, chemical reaction experiments, quality inspection, and product development. Distinguished from plastic laboratory equipment by material composition, suitable for high-temperature, strong acid, and strong alkali experimental environments. Includes precision measurement instruments compliant with JIS and DIN standards, essential basic equipment for analytical operations in manufacturing facilities.
