170oz(5000ml) Sturdy Glass Beaker, Heavy-Duty 5L Lab Beakers，3.3 Borosilicate Low Form with Printed Graduation, BKL5K0-001

Yes, thick glass, large capacity. Oh, great price, I recommend this Becker.

It's glass one was broken upon receiving went ahead and returned through amazon no problem!If willing to pay what they ask for, they work fine they work fine.

Thick rim, same as it looks in the picture.

As far as I can tell they are accurate measurements. They are made of glass so they are easy to clean.

Well packed, nothing broke. Markings are clear.

Thank u

It broke in my sink for crying out loud!!! Also, don't have any faith in the measurements on the side. They're not even consistent from jar to jar. I literally went through and measured from chart to jar and realized why my formulas had been off. I actually relied on them for accuracy on the measurements and they were skewed. So make sure that you're using a scale at all times because the lines are wrong and the glass is weak and temperamental.My United Scientific beakers would never.Invest your money elsewhere.

It is a nice set. However, it was broken upon arrival. I slightly sliced my thumb pulling the stacked 500 ml beaker out of the 1000ml beaker. It looked completely intact. Be careful when taking out of the package or try another brand.
