All plastic soda or 'pop' bottles start as a small plastic bottle called a preform. When this preform is heated and blown into a larger bottle it is ready to be filled with your favorite carbonated beverage. Our small plastic preforms come with full-sized final threaded openings so they use standard plastic soda bottle tops (included). Use them for a problem-solving activity by seeing if your students can guess their use. All bottle caps may be used again and again. These preforms are air and water tight when covered tightly with a bottle top and so are perfect for collecting or storing liquid samples.

Preforms are ~12 cm long x 2.5 cm in diameter (~5 in. x 1 in.). Interior volume of preform is approximately 28 cc (~1 fluid oz). The polymer in our baby soda bottle preforms is polyethylene terephthalate, commonly known as PET. This polymer has a monomer formula mass of C10H8O4, a melting point of 260o C, and a specific heat of 1.0 kJ/(kg-K). It has a glass temperature of 70o to 80o C, where it starts to soften. Package contains 30 Preforms and 30 bottle caps. Bottle caps sold separately as well. Cap color may vary.

Note: Heavy/Dense item. Higher shipping rates may apply, especially for express orders, and orders to Alaska and Hawaii
