Polypropylene and polymethylpentene beaker with “Design Ratio” printed 

• Shatter resistant - Reduces breakages and injuries! 

• Choose polymethylpentene polymerization (PMP) 

• Choose economical translucent polypropylene (PP) 

• Chemical resistance to most acids, bases, and many common solvents 

• Autoclavable Square beakers are the safe and practical alternative to Griffin style beakers. 

These beakers have a vertical lip around the top of the beaker, which has two purposes: 
first, the lip contains numerous splashes that are likely to occur with the design 
 rounded off with a griffin-style beaker. Second, this vertical lip allows cups to be stacked in 
series when not in use. The maximum temperature for PP is 135°C; 
PMP is between 150°C and 180°C for short intervals.
