SCIENCENT Glass Beaker Set of 6 Borosilicate Thick Wall - 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml (Set of 6)

I use these to make Vape Juice for my friends and I. The lines have accurate markings, glass quality is good, and they’re easy to read the measurements.

TL;DRPros:Great customer servicePromt customer serviceGood productCons:Glass beaker may lose a fight with a cast iron panMeasurements on the glass may not be accurate, measure contents before filling I'd recomend.I have used these beakers for a long time. I probably didnt need to order another set but my roommate had a slight kitchen mishap and the glass beaker broke (allegedly the beaker and a cast iron pan got into a fight, the pan has been taken in for booking, roommate sticks to her story she was out of town).When the shipment arrived, one of the beakers was broken (worst nightmare, right?). Amazon wanted me to ship the broken glass back but I contacted the seller directly (their info is all on amazon, it was easy)and made sure they did want a box of broken glass. Shockingly they said no (and they replied within the quarter hour).A few emails back and forth in under 24 hrs (sending pics and clarifying things) they sent a new shipment out.When it arrived in a few days (i think 3) they sent A ENTIRE NEW SET. They were a pleasure to work with, very prompt and kind.I feel bad that glass broke during shipping, but that just might be the nature of the game with shipping delicate things. There a good amount of foam padding in the box, so I believe it was the RND gods bestowing their blessing on me.The beakers are good, I dont trust the markings on the bottle to be 100% accurate. I measure the weight and the Ml of what I'm working with to be sure. But it looks close for a inaccurate job (it all depends on what you use these for. I mix some not friendly chemicals, so I need to be acccurate).10/10 will order again as needed (hopefully the cast iron pan gets denied parole and my roommate doesnt "go out of town" again.

Very nice accurate and heavy glass.

This was my third attempt at buying decent Set of beakers the first set I received from another company was broken and very thin. Ended up returning them and ordered another set from another company and those I received were extremely thin almost afraid of setting them down thinking they would break the third set I ordered I just received an opened up and am surprised at the quality, the lip of the glass is thicker than I was expecting and is made of decent quality marking seem to be very accurate

I bought these to make things with so wasn't too bothered that one was cracked since borosilicate is easy tto work with. It was cracking from thermal shock even after long exposure to heat. I don't know what these are or if the mixture is bad, but these things are way more brittle and the co-efficient of thermal expansion isn't proper to borosilicate.

I had some hesitancy about ordering these beakers since I wasn't sure whether there were 5 or 6, and there were reports that they came soiled and/or broken. What I got were six beakers in the sizes indicated. All were low form except for the 50ml which was twice as tall as the 25ml (see image) -- kind of weird, I'd never seen a beaker of that aspect ratio; however pouring from it should be easier than in the case of the low form shape. Btw, pouring from a low form beaker that is more than half full is usually unwise -- owing to the geometry involved the liquid will tend to pour out in a wide stream. The beakers were clean, although I did wash them since I may use them for food prep. They all arrived unbroken. Given the huge amount of packaging/padding involved (see image) I can't imagine how it would be possible for breakage to occur in shipping unless dropped from a plane onto rocks. The graduations are typical for beakers (see image), i.e. they are approximate, fine for cooking, not so much for analytical chemistry. If you're interested in accuracy, look into graduated cylinders, pipettes, and volumetric flasks. They claim to be borosilicate glass; if they were properly annealed, they should be similar to Pyrex or Kimax with regard to thermal stability. I haven't heated them.

I was so happy to receive this set for soap making. The different sizes are super-useful, and it was packed EXTREMELY well and nothing was broken. I keep all the packing stuff to pack them back up because I'm making soap while traveling. And everything still fits safely back in the box. I try never to take them from boiling hot to freezing cold or anything, but I've accidentally boiled some soap over in one of them and it was still just fine, so they can handle pretty hot temps. I am really not sure about the accuracy, because I don't need exact measurements. Good set and good value. The tiny one and the tall tiny one are really good for colorants and scents.

The glass in this set is super thin that a couple of the beakers broke in transit. It's so thin that I would not recommend using them when double boiling because they will definitely break in the water. I returned them and would not purchase again.
