ULAB Scientific Glass Beaker Set with Magnetic Stir Bar Offered, 5 Sizes 50ml 100ml 250ml 500ml 1000ml, 3.3 Boro Griffin Low Form with Printed Graduation, UBG1002

Bought these to use with a magnetic stirrer to make structured water and play about with electrolysis which I haven’t done yet. They are very well made, feel sturdy and professional. Came beautifully packed, one inside the other like Russian dolls. Plenty of cardboard padding to prevent breakage whilst in transit. Good value too! If you’re in the market for a pair of beakers, I recommend these unconditionally. Disclaimer: I have not worked with heat or any aggressive chemicals in these beakers so can’t attest for their suitability with these conditions.

Perfect set - you have every size you need and they are good quality

It will smash with the the smallest of drop. 10CM. It will shatter under thermal load and shock. This IS a liability to you and your experiments. There was a man who lost his hands in a experiment to "pyrox glass" and not Pyrex. This might as well be pyrox glass full of eastern promise. Do not buy if you are a real scientist/ experimenter.

I don’t personally have a science lab but do use these lab style beakers as I make my own skincare products and they are perfect for the heating stage as they can go in a pan of hot water and then fairly quickly cooled with no fear of them breaking. As I weight all of my ingredients I cannot say if the measurement marks are accurate, and likewise I’ve not used them for ‘scientific experiments’ so cannot comment on whether they will withstand the rigours of such, but for my purposes they seem perfectly fine. This set seems good quality, decent thickness glass, and having the two sizes, 500ml and 1000ml is great as I can now make larger quantities at a time. I’ve used them for a couple of batches of cream and so far so good.

Really disappointing. The smallest and largest beaker were both broken.

Low Form Glass Beaker, Vol.1000ml - not 6.22" tall. I measured the height as 5.75" but the stated capacity of 1000ml is as described. I bought (and returned) this 1000ml Low Form Beaker complete with a Stirrer. Low Form means that it is wider than other designs. The biggest issue is that the manufacturer has reduced the height above the 1000ml mark by about 50% vs the supplied images. This means that there is no margin for setup, using the Stirrer with 1000ml of liquid (water), without the possibility of liquid flowing out of the spout. If your requirement is to only mix 800ml then it is OK but there are other Low Form Beakers which do have the additional head height available. A secondary issue is that the supplied Spinner doesn't have the magnet centred. At low speed the Spinner rotates but at a higher speed, it rotates off axis and can be thrown off so that the liquid is no longer stirred by the Spinner. Whilst that is interesting to know it doesn't effect the operation and may be limited to just one sample. The product would be OK to mix 1000ml in two 500ml batches but that would defeat the object of using the bigger size. One good point is the product is supplied in a cardboard sleeve with end caps. So it wasn't broken when received, especially as the labels saying it glass and fragile didn't effect it being delivered in just an Amazon paper bag.

The measurements are wrong, they're not lab-quality, and the bases are fairly fragile. Weird.

I bought these beakers for work. On the first use one broke as you can see. The thickness of the glass on the bottom is very thin, a couple of taps with a plastic spatula is all it took to break it. I'd look elsewhere if I were you.

Stabil und hitzebeständig. Kaufempfehlung!

It reached me broken

Accurate enough for non critical use. The large diameter may be a difficult grip for small hands.
