EISCO 12PK Graduated Cylinders, 100mL - Class B Tolerance - Octagonal Base - Polypropylene Plastic - Industrial Quality, Autoclavable

Needed these for a product I'm developing and need to do a bulk production with precise measurements. These fit the bill. The lines are clear and concise and now I can have others help me because they just fill to the line. Very glad I made this purchase. Saves me a lot of time

Using it to soak my own incense! Perfect size for 30 stick batches.

donated them to my son's elementary school .... priced well!

Perfect for my science class. Sturdy and markings easily read by students.

I teach sixth grade science and wanted to do a density lab. As this was the first lab of the school year I wanted to use plastic in case my students were a bit clumsy. I was nervous that the plastic would be too clouded for them to clearly see the levels of the liquids. All turned out well. The lab was a complete success!

Cylinders arrived promptly and were individually wrapped. They were clean and in perfect condition and are made from what appears to be a very durable material (probably polypropylene but no recycling symbol is present). I used them for a purpose that did not require accuracy so am I not sure how accurate the gradations are - this is the ONLY reason why I am not giving five stars.

Good quality! Made great graduation gift for chemistry students

great for measuring small amounts of liquid in elementary school. Easy to read....wish it were a clear plastic instead of a muted plastic.
