PMP (TPX) Graduated Cylinders with Molded Graduations | Globe Scientific
PMP graduated cylinders with molded graduations from Globe Scientific combine crystal-clear transparency with superior chemical and thermal resistance. Polymethylpentene (PMP), also known as TPX®, offers glass-like optical clarity in an unbreakable plastic body — ideal for laboratories requiring both accurate visual readings and shatter-proof durability.
These measuring cylinders feature permanently molded graduation marks calibrated in milliliters. The wide pentagonal base provides exceptional stability on crowded benchtops, while the tapered pour spout allows precise liquid transfer. PMP withstands temperatures up to 170°C, significantly higher than polypropylene alternatives.

Why Choose PMP Over Polypropylene?
PMP (TPX) graduated cylinders offer three key advantages over standard PP cylinders. First, crystal-clear transparency provides glass-like visibility for accurate meniscus reading. Second, the higher temperature tolerance (170°C vs 135°C) supports more demanding thermal applications. Third, PMP resists a broader range of organic solvents that may attack polypropylene.

Frequently Asked Questions
What does TPX stand for?
TPX is a registered trademark of Mitsui Chemicals for polymethylpentene (PMP). Globe Scientific PMP cylinders conform to ISO 6706-1981(E) and BS 5404 Part 2 international standards.
Are PMP cylinders really as clear as glass?
PMP offers the highest optical clarity of any laboratory plastic. While not identical to borosilicate glass, PMP transmits light at rates approaching glass, making meniscus readings straightforward without the breakage risk.
