stonylab Rubber Stoppers Editorial Review
The StonyLab Glass Hex Head Hollow Glass Stopper is a great addition to any laboratory or home distillation setup. This stopper is perfect for 2440 outer joint glass with a closed bottom, making it versatile and easy to use. The hexagonal head adds to the appealing design, while the high-quality finish gives the stopper a professional look. The stopper is lightweight and fits the 24/40 ground glass connection perfectly. Although the glass is thin, it is not meant to be abused, and the quality is worth the slightly higher price tag. One reviewer did mention that the stopper is not airtight and leaks if used for cleaning, so it may not be suitable for every use. However, the majority of customers were satisfied with the product's design and quality, with one noting that the material feels and looks great. Overall, if you are in need of a glass stopper for your laboratory or distillation setup, the StonyLab Glass Hex Head Hollow Glass Stopper is a good option.
