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 C10
, a melting point of 260o
C, and a specific heat of 1.0 kJ/(kg-K). It has a glass temperature of 70o
C, where it starts to soften.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s)
Students can use Mixing Wells in an investigation to describe and classify different kinds of materials by their observable properties.
Students can use Mixing Wells to make observations and measurements to identify materials based on their properties.
Soda Bottle Preforms can be used to develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Students can make observations of the Mixing Wells to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Students can use the Mixing Wells in an investigation to analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Students can experiment with the Mixing Wells to evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Soda Bottle Preforms can be filled with water and a piece of aquatic plant, and placed in the direct sunlight. Students can construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
Soda Bottle Preforms can be filled with water and a piece of aquatic plant, and placed in the direct sunlight. Students can use this to illustrate how photosynthesis transforms light energy into stored chemical energy.
Soda Bottle Preforms can be used to investigate, construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
Soda Bottle Preforms are clear, sturdy and have a firm seal conducive to a number of classroom activities or storage of samples.
