This Grinding-mouth conical bottle (Stacking) from Canrd is designed for laboratory liquid handling and storage, particularly in chemical synthesis and sample preparation workflows. Constructed from high-quality glass, it features precision-ground conical joints that ensure reliable sealing and compatibility with standard glassware connections. The stackable design allows efficient vertical storage, minimizing bench space usage when multiple bottles are used simultaneously. Available in a range of capacities from 50 ml to 300 ml, each size maintains consistent wall thickness and thermal stability for routine heating or cooling applications. The borosilicate-type glass construction resists thermal shock and chemical corrosion, supporting repeated use in research and quality control environments. This product is suited for both academic labs and industrial R&D settings where durability, ease of stacking, and secure fit are important.
