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

This vessel is very well made. The markings are easy to read and it is sturdy enough to handle daily use. It can thermal cycle without cracking.

Well made set.

I was tired of cheap glassware, this is two or three times thicker, much more sturdy. I will look here to Maccx Scientific in the future.

Looks good, only issue was 1 of the beakers had a broken pouring tip. Glass looks a little skinny but hopefully all works well

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

Ok quality. They worked fine for my application but I’m not sure if I would recommend them if accuracy is absolutely essential to everything. I’m not sure on the extent of their accuracy but from the appearance of the glass in comparison to high priced lab glass it might as well be a glass from your kitchen.

The bottoms of the glass beaker is not flat. PLACED ON A LAB HOTPLATE IT WILL "ROCK" BACK AND FORTH. IN ADDITION IT IS VITAL FOR THE GLASS TO TOUCH THE FLAT SURFACE OF THE HOT PLATE TO ENABLE SAFE UNIFORM HEATING OF THE GLASS BEAKER WALLS AND ITS LIQUID CONTENT. This is a dangerous product and should be withdrawn from the market to prevent potential injury to the User. We destroyed the 4 we ordered at a $200 loss so that they are not returned into the customer stream if they were returned to the manufacturer.

Thick rim, same as it looks in the picture.
