Measuring Cylinder Set, 4 Sizes Graduated Polypropylene Lab Test Tubes in 100 ml, 50 ml, 25 ml, 10 ml for Laboratory, & Science Experiments with 4 Plastic Droppers in 3 ml

Exactly as described. Would buy again.

I immediately put these measuring tools to use I am very happy with the quality and the readability and the accuracy and the actual performance of the instruments.

I got these to measure additives that I use in my aquariums. I did not have anything accurate to use for the small quantities required. These work well and they are easy to clean

100 ml arrived broken. I have a 100 already. I needed the smaller ones so not bothering to return. Still sucks.

Droppers didnt come with measuring cylinders although they were advertised, was really looking forward to using those

I like these but be gentle washing the writing on outside because it fades

Works for measuring fluid volumes accurately compared to certified standard measuring device .

Good product, I've used multiple times now and no staining has shown up. Cleans up nice. Plastic, but they aren't getting cloudy or stained and they seem to be made well. It does the job!
