[b said:Quote[/b] ]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. Our bottle caps are brand new and include an integrated safety ring so that you know if a sample has been opened after it has been sealed once. 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" x 1"). Interior volume of preform is approximately 28 cc (~1 fluid oz). Package contains 30 Preforms and 30 bottle caps. Bottle caps sold separately as well.
