Glass Erlenmeyer Flask Sets, Borosilicate Glass, 3 Sizes - 50, 150 and 250ml, Karter Scientific (Variations Available)

Super happy with my purchase! I bought these with plants in mind. I've been fooling around with water propagation and thought these would make cute containers. Happy to report everything looks great!Based on the reviews I honestly thought they were going to be a bit smaller but they're great! All arrived in perfect condition. No broken pieces.

They make great vases for plant cuttings. I have them on my desk at work and everyone smiles when they see them lined up with plant cuttings - you can easily watch to see how the cuttings are rooting. The plants appreciate the small opening so they don't slip into the water. Use them together on your desk. I think the small top opening helps keep oxygen in the water and prevent evaporation. I use them in an office with no natural light.

Perfect for my son's mad scientist party and now a staple in my mixing essential oil blends. They are smaller sizes which is great for making small batches of product. Great quality. Like many erlenmyer flasks, they aren't 100% accurately marked so if you plan to use them for measuring, calibrate them with a graduated cylinder and water first so you have an accurate proportions.

These are functional but there are bubbles in the glass on the rims. I haven't tried heating them yet but I have my doubts.Otherwise they are perfect. Just wish there was a little more craftsmanship in these.

I ordered the glass Erlenmeyer flask set but received a beaker set. It will need to be returned. Unfortunate for my class, as they will need to wait to complete their lab.

Ordering glassware online can be a bit of a risk but these shipped quickly and were very well packaged in individual boxes. They arrived in one piece, the markings are clear and they were reasonably priced. A good addition to our Homeschool labs

I bought these flasks to replace a beaker that my mom embedded a candle in. They were very inexpensive and highly rated, so I thought I'd try them out. I ordered them on Monday, and they arrived the following Thursday. Very fast shipping. They were packaged pretty well, and I opened them up immediately. The largest one had some dust in it, but a quick wash quickly cleaned it off. The middle beaker's markings were a little smeared, but they still function properly. I have used them a little since, and there are no scratches or bubbles in the glass. Overall, they are good flasks.

I bought these for a decorative science experiment with colored water and dry ice for my daughter's science birthday party. They are great quality. I'm sure as a homeschool family we will find many more uses for them!
