Science enthusiasts and home lab users, this 4-piece borosilicate glass funnel set is absolutely essential for any serious work! The borosilicate glass is the good stuff - it handles temperatures up to 800°C (about 1500°F) without cracking and has amazing chemical resistance. You get four different sizes: 40mm, 50mm, 75mm, and 100mm diameters, so you're covered for everything from small precise pours to larger transfers. The smooth surfaces and round edges make cleaning super easy, and the glass is reusable and environmentally friendly. I use these not just for lab work but in the kitchen too - they're perfect for transferring oils, making homemade perfumes, or filtering herbal extracts. The quality is professional-grade with no rough edges or imperfections. They're heavy enough to feel substantial but not clumsy to handle. Whether you're doing chemistry experiments, essential oil work, or just need reliable funnels for various liquids, this set delivers exceptional value. The glass is surprisingly durable - I've knocked them over a few times and they've survived just fine. Just be careful during shipping since glass can sometimes arrive broken, but the seller is good about replacements.
