8oz Amber Glass Boston Soap Bottle with Pump for Personal Care Use

The Boston Round bottle is characterized by its classic cylindrical shape, short curved shoulders, and a rounded contour. This geometric profile distributes physical impact uniformly across the glass walls, eliminating the concentration of structural stresses found in square or sharp-cornered bottles. This makes it highly dependable for storing liquid chemicals, diagnostic reagents, and liquid APIs.

Our molded Boston Round bottles follow standard GPI/GCMI thread profiles, primarily 18/400, 20/400, 22/400, 28/400, and 33/400. These universal threads allow clients to source components locally or use various standard closures, such as fine-mist sprayers, lotion pumps, phenolic polycone caps, or dropper pipettes.

Yes, they are made of premium molded USP Type III soda-lime glass. Because glass is chemically inert and completely impermeable to gases, it provides an exceptional barrier for volatile essential oils, alcohol-based liquid formulations, and mild solvents that would degrade or permeate plastic containers.

We produce a comprehensive range of Boston Round sizes: Small sizes: 1/2 oz (15 ml), 1 oz (30 ml), 2 oz (60 ml) Medium sizes: 4 oz (120 ml), 8 oz (240 ml) Large sizes: 16 oz (480 ml), 32 oz (960 ml)

Our pharmaceutical-grade Boston Round bottles are manufactured with thicker walls and a robust base compared to retail or food-grade cosmetic glass. We maintain a minimum wall thickness specification (typically greater than 1.2 mm to 1.5 mm depending on size) to meet the mechanical durability standards required by automatic pharmaceutical filling lines.
