50mL Polypropylene Plastic Beaker – Pack of 12
by United Scientific

This Griffin style beaker has an graduated capacity of 50mL, with an outside diameter of approximately 55mm, or 5.5cm, not including the lip, and a height of 55mm (5.5cm). The graduations go from 5mL to 50mL, and are numbered every 25mL.

Molded from a single piece of polypropylene, these plastic beakers feature raised graduations for easy readability. This also ensures that, unlike painted on graduations, they aren’t susceptible to fading or paint rubbing off. They are fully autoclavable, and have excellent contact clarity. The round broad round base at the bottom of the cylinders provides good stability.

Similar to polyethylene, polypropylene features an additional methyl group that adds improved mechanical and thermal resistance. At room temperature, it is resistant to fats and almost all organic solvents, save for strong oxidizers. It can also handle non-oxidizing acids and bases with relative ease. Max usage temperature is 135 degrees Celsius.
