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

They’re glass beakers with measurements. Not much to say. They’re nice and thick enough to not feel cheap or easy to break. They’re perfect.

***REVISED as of 6.20.19*** The company reached out to me after reading my review and offered to replace the broken beaker. It was such a pleasant surprise. The replacement arrived today and I’m very pleased. I appreciate the consideration of this company and will order from them again knowing that they stand behind their products.This is the first review from my original purchase in March 2019: Used this product for the first time since purchasing about a couple months ago. It seemed to withstand the heat of the double boiler but when I accidently knocked it over while it was sitting in the sink, it broke as if I had dropped it on the floor. Sooo disappointed.

Love these guys, super thin but laboratory grade and the marking on them have held up over a good 50 washes so far.

Who would have thought I would enjoy such a purchase? I bought these for making lotion so I can fit my oil phase and water phase in the same double boiler. I also like them for measuring really small amounts bc they weigh almost nothing so my very precise scale isn't overloaded with just the vessel itself which has happened before. They're great for measuring essential oils which will eat through plastic cups. I've found other uses too surprisingly when you need to measure really small amounts. I keep them stored with the perfectly sized cardboard protectors between each one that came with them when they shipped.I haven't washed them in the dishwasher so Idk if the measurement lines wear off after time.

This is not a large Beaker set, the largest beaker in this set is less than a Quart

Perfect product

Title

The media could not be loaded. Two of the beaker came broken. The glass is not thick, it’s thinner than my drinking glassware. It’s only1.5mm-thick. Heavy Wall beakers are typically 4mm thick. I definitely would not feel comfortable heating or stirring in these. I can’t believe they sell stuff this dangerous. The bottoms aren’t flat so the stir bars rattle very loudly.
