Description
This polypropylene rack is perfect for holding six preforms. It has openings of 25 mm (~1") diameter on a top plate with hemispherical wells and drying pins. Dimensions: 24 x 7 x 9 cm (~9.5" x 2.75" x 3.5") Also available as a kit that contains six soda pop bottle preforms, new caps, and one of our awesome perform racks. Cap color may vary. Note that preforms have a larger diameter than most test tubes and so don't fit easily into standard test tube racks. Our polypropylene rack fits perfectly, resists spills and stains, and even incorporates built-in drying pegs. Use them as a display on your science table with soil to make sedimentation tubes or add mineral oil and colored water to make mini wave machines. The possibilities are endless. Preforms are ~11 cm long x 2.5 cm in diameter (~4.3" x 1"). Interior volume of preform is approximately 25 cc (~0.84 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.Preform & Rack Kit
