Plastic Beaker Set, 5 Sizes Low Form Measuring Graduated Griffin Polypropylene Beakers in 500 ml, 250 ml, 100 ml, 50 ml, 25 ml for Laboratory, & Science Experiments with 5 Plastic Droppers in 3 ml

Product worked as expected. Material is durable and strong and it cleans out great. Happy with the beakers and the wide range of capacity’s come in handy

They work well with my magnetic stirrer and I like the included droppers.

Cute and functional set but I miss the inclusion of ounces. My fault for not checking.

Needed something cheap and unbreakable. These did the job.

Smaller than expected but worked ok

Great product for kids learning to measure and develop STEM skills! Grandkids love them. Seems very durable and are easy for grandma to help read measurements.

Using these to mix paint. They work great and are easy to clean.

These cannot be used for mixing oil and water phase ingredients requiring heat unless you use a double boiler approach. Placing them directly on my magnetic stirrer mixer caused the bottom to melt off the beakers within 1 second of contact.I'm starting to think this is not real Polypropylene because it has a melting point of 160c and the plate was probably closer to 120c. I tossed some water on the plate while it was hot and it only slowly bubbled off over a minute.
