Round bottom flasks are frequently used in labs due to their spherical bottom. This base provides a uniform heating and stirring of liquids making them suitable for activities such as distillation, mixing, or heating. Due to their ability to contain liquids while still optimizing stirring and heat uniformity, these flasks can be found in many scientific experiments, pharmaceutical research, and other scientific endeavors.

Round Bottom Flasks feature a wide neck and round bottom, which make them ideal for tasks requiring reflux, distillation, and other types of heating processes. With the wide opening, users can easily measure, mix, and pour into these flasks. The round bottom ensures optimal heat distribution for even and reliable results.

Round Bottom Flasks/ Boiling Flasks are manufactured from BOROSILICATE 3.3 glass and come with a thick beaded rim in order to reduce breakage and chipping.

Definitely an essential jacket for athletic-wear & flattering
Special Size Type: Full Zip, Size: XX-Large, Color: Black
Great quality for a great price! I was looking for a versatile athletic jacket to run in that fits over light tops & found this on Amazon. There were only a few left so I grabbed it right away, so glad I did! It's warm enough for early fall, I live in NC so I will probably use it throughout the winter too bc it's warm here. I feel like the arm length is a bit long & the sleeves a little bit tight under LS Tops but are meant to be. This is a form-fitting jacket, it does run small. I usually have to size down from an XXL to an XL in Amazon Essentials clothing bc they run big but this jacket fits me in my regular size XXL. I tried to find this type of jacket at a few different places & already out of stock in October! If it's available, buy it! You'll love it! I hope more colors are available in the future!

Nice looking and soft
Special Size Type: Full Zip, Size: XX-Large, Color: Slate Grey
Soft fabric and great color (grayish purplish/bluish). Pants fit nicely, but I may have been able to size down just for how high I can pull them up and them slipping down. On the other hand, I wish the jacket was bigger. It fits probably like it’s supposed to but you can definitely see every lump on my stomach. I will wear it unzipped. The material is medium weight, very stretchy, and nice. I do think it will probably pill- it just seems like things I’ve had that do. I won’t dry it. I’m 5’4” and weigh 195.
