Feekoon 10 Pieces Glass Measuring Beaker and Graduated Measuring Cylinder with Stirring Rod 50/100/ 250/500/ 1000 ml Thick Glass Beakers and 5/10/ 50/100 ml Graduated Cylinders for Science Lab

All of my pieces came whole, but there waa broken glass in the packaging. Other than that, it's a handsome looking set. Will update once they touch high strength acid.

Bought for my wine lab, measurements are accurate.

The beakers and cylinders will probably not be your point of failure. The point of failure is with the funnels and stirring rod you will use since these break more often. Okay that's not really a 'catch' like in my headline. More like a note. And the funnels are sold separately so I'm not sure I need to mention it. But here we are. The glass beakers and cylinders are quite thick, and have performed well in different experiments and while mixing highly caustic solutions. You will want to use a retort stand (beaker support support stand) with a decently weighted base to minimize the possibility of accidents. Heat resistsance and heat transfer is within the normal range of borosilicate and the graduations are easy to read. I use the 'patch' of white on the side to note information I dont want to forget in the process of an experiment or while distilling a solution. Grease pencil a.k.a China marker works well and I've never had a problem with it melting away while heating. Since it is relatively affordable and durable (for glass anyway), I can recommend the Feekoon 10 piece set to both the home amateur, professional, or parents who are throwing a science-experiment themed birthday party. JHA

Definitely not bad for the price. Beakers came fine, no cracks, and well packaged, but 2 of the graduated cylinders came cracked at the base (still stand) and I didn’t receive my glass stirring rod. Can’t figure out how to contact the seller about this.

One beaker broken 500ml the rest came in good condition. Would said packing issue from factory as the broken was nested inside the other beakers. The outer and inner beakers are good. Figured would possibly be an issue as others stated with other reviews. Since only needed the 1000 ml at the time did not return. And the others were to have on hand.

Packaged AMAZINGLY WELL !!!

Perfect in the anticipation of using them soon. This for my son who is 16 years old. Thin glassware, but at this price would you expect more?

ok so most notable factor: environmental concerns be damned, they went all in on the packaging just short of putting a frame of wood or steel around them. even if the courier were to throw this box over a fence theres a decent chance everything will still be usable. after i opened the box i was greeted with a sea of dense crumpled paper padding with a large chunk of packing tape wrapped cloth. i cut around 4 layers of cloth/foam/paper wrap before i even got to a point where i could even take a peek at the beaker. overall performance of the beakers is meh, honestly i'm not a good judge of looks and borosilicate glass is gonna be good regardless of who shaped it so long as there are no defects. i did confirm that it is in fact borosilicate by heating the 1000l beaker up to ~100c (~200f) and dumping icewater into it; it is indeed borosilicate or at the very least it has good thermal shock properties. i broke all my beakers plus hotplate in something of a "bad idea" style of experiment so i got these to replace, no issues so far. honestly i wouldn't write this review if it wasn't for the extreme level of care with the packaging, i was actually kinda impressed. my last set i ordered somewhere else and they did the bare minimum. 10/10 would buy again.

I was surprised and pleased that these arrived all in one piece. They are good quality and I find the measurements to be accurate.

All arrived wrapped in padding, seller has done their best to secure glasses ( cant account for courier obviously) to arrive all in one piece

The quality is good . Delivery arrived early as well. Really happy with product and sery
