• ASTM-Compatible Design: Supports penetration testing of bituminous semi-solid materials.
• Label-Friendly Surface: Smooth outer walls make product and sample labels easy to apply.
• Compact Size: The 1 15/16-inch diameter fits neatly in storage cabinets and work areas.
• Bulk Case Pack: Includes 100 tin bottoms for laboratories, manufacturers, and industrial facilities.

The 1 oz flat-bottom industrial round seamless tin bottoms provide compact sample retention, bituminous material testing, salve storage, and ointment packaging for laboratories and production sites. Each metal container bottom offers a smooth surface, durable seamless construction, and a space-saving shape that helps you manage small semi-solid samples with less mess. These one-ounce tin bottoms conform to ASTM specifications for penetration testing of bituminous semi-solids. Their flat base keeps each container stable on laboratory benches, inspection tables, and storage shelves. You can use them to prepare, hold, identify, and retain controlled samples during quality checks, material reviews, and routine industrial testing procedures.

The seamless body has no side seam that could interrupt the interior surface or create an uneven labeling area. This design makes the tin useful for salves, waxes, ointments, pastes, and other non-liquid materials. The smooth outer wall also gives you a clean area for batch numbers, dates, product names, and handling instructions. Each tin bottom measures about 1 15/16 inches in diameter and 3/4 inch high. Its compact profile helps conserve storage space while keeping small samples separated and easy to access. The one-ounce size works well when you need enough material for testing or evaluation without using a larger container than the task requires.

This package includes 100 bottom sections under item number 81-BOT. Tops are not included and must be purchased separately. Matching slip-on tops provide a snug fit when paired with these bottoms, but the complete container isn’t designed for liquids. Use these tins only with suitable solid, semi-solid, or low-flow materials. These industrial round tin bottoms can support many tasks beyond laboratory penetration testing. You can use them for product development samples, fragrance balms, polishing compounds, repair waxes, grease samples, cosmetic prototypes, or small parts sorting. Their uniform shape also helps teams create consistent sample sets for customers, inspectors, technicians, and internal review groups.

The lightweight metal format is easy to carry between workstations, testing areas, and storage rooms. Because the tins arrive in a 100-count case, you can assign fresh containers to separate batches or projects. This helps limit sample mixing and makes routine tracking easier when your process requires clear identification and organized retention practices. For best results, pair each bottom with the correct separately sold top. Apply labels only after the outer surface is clean and dry. Avoid water, solvents, oils, and other free-flowing liquids because the slip-on closure isn’t leakproof. Confirm that your stored material is compatible with the tin before beginning long-term retention or transport.
