Graduated Cylinders, Polymethylpentene - Economy Choice
Polymethylpentene plastic is almost as clear as glass. It is very strong and will resist breaking after frequent impacts. Generally, the chemical resistance is outstanding except in the presence of very strong oxidizing agents. Prolonged exposure to hydrocarbons will cause the plastic to cloud. These graduated cylinders are precision molded and usable to 175 ºC. You will find these graduated cylinders worth the investment. To reduce breakage, plasticware provides a durable alternative to glassware, especially for young students. While Graduated Cylinders, Polymethylpentene do not provide the same chemical and heat resistance as glass, it is a cost-effective alternative in some applications.
