Review: Better than expected - Never bought anything like this before however I wanted to make a tincture using the percolation method. This dropper bottle is a much higher quality than I was expecting which was a pleasant surprise. The glass has a nice weight and thickness to it. The photo I’ve included shows it setup on a stand with the dried herbs and alcohol macerating overnight. A teeny tiny drop of fluid did seem to have slipped through the stopper even though it’s in the closed position. That’s not a big deal for my purposes though. The video shows it in action! 153 proof alcohol running through dried Soursop leaves. Why did you pick this product vs others?: the size is suitable for small batch making Leakage: one tiny drop of fluid after sitting overnight Build quality: sturdy Review: Works great - Excellent purchase. Works as designed. Clean up is a breeze thanks to the tapered design of the stopcock. ## Features - Made of high quality, Borosilicate glass - Cylindrical Dropping Funnel, made of high quality borosilicate glass - Open top with PTFE Key Stopcock - 500ml capacity - Perfect for any science or home laboratory ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DFS5ZSK | | Best Sellers Rank | #115,637 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #60 in Lab Funnels | | Brand | EISCO | | Brand Name | EISCO | | Capacity | 500 Milliliters | | Color | Transparent | | Customer Reviews | 4.4 out of 5 stars 77 Reviews | | Global Trade Identification Number | 00849230023430 | | Item Dimensions W x H | 2.5"W x 14"H | | Manufacturer | Eisco | | Material | Borosilicate Glass | | Material Type | Borosilicate Glass | | Model Number | CH0470D | | Part Number | CH0470D | | Product Dimensions | 2.5"W x 14"H | | UPC | 849230023430 | | Wide End Diameter | 2.5 Inches | ## Product Details - **Material:** Borosilicate Glass - **Brand:** EISCO - **Capacity:** 500 Milliliters - **Product Dimensions:** 2.5"W x 14"H - **Item Weight:** 14.4 ounces ## Images ![EISCO Dropping Funnel, 500ml - PTFE Key Stopcock, Open Top, Cylindrical - Ungraduated - Cylindrical, Borosilicate Glass - Image 1](https://m.media-amazon.com/images/I/517I1VLSqpL.jpg) ![EISCO Dropping Funnel, 500ml - PTFE Key Stopcock, Open Top, Cylindrical - Ungraduated - Cylindrical, Borosilicate Glass - Image 2](https://m.media-amazon.com/images/I/41Tecq61KZL.jpg) ## Questions & Answers **Q: Can its stopcock handle highly corrosive chemicals?** A: Yes, the product is manufactured to withstand harsh lab environments. **Q: Is it resistant to thermal shocks & high temperatures?** A: Yes, the product can withstand both thermal shocks and high temperatures. **Q: Does its stopcock allow precise drops or flow?** A: Yes, the stopcock allows for controlled and precise flow. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than expected *by J***Z on June 28, 2025* Never bought anything like this before however I wanted to make a tincture using the percolation method.
