Review: These are fantastic great price - Beautiful glaswere for my lab and will be used very soon prober size fit my heating mantel perfectly Review: Thick glass, durable but doesn’t fit keck clips - First arrived damaged but seller replaced immediately. Delivered in a bulging polystyrene box so no surprises why the first got smashed. The glass is pretty thick so I’m not worried about accidentally smashing it on something, but thermal gradients may be an issue. The ground joint is also very thick glass and is too big for keck clips, they should really provide a special clip with the flask if it’s going to be that chunky. Joint fits other glassware well. ## Features - Single neck round bottom boiling flask - Capacity(ml): 250 - With 24/40 ground joint - Made of Borosilicate 3.3 glass - Heavy wall, durable design ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZYPKSNX | | Best Sellers Rank | 74,648 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 85 in Lab Flasks | | Bottom Shape | Round | | Bottom shape | Round | | Brand | DONLAB | | Capacity | 250 Millilitres | | Country Of Origin | China | | Customer Reviews | 4.9 out of 5 stars 12 Reviews | | Graduation Interval | 250 Millilitres | | Graduation interval | 250 Millilitres | | Manufacturer | DONLAB | | Manufacturer Part Number | FLK-01-250 | | Material | Glass | | Material Type | Glass | | Specification Met | CE | | Specification met | CE | ## Product Details - **Bottom shape:** Round - **Brand:** DONLAB - **Capacity:** 250 Millilitres - **Graduation interval:** 250 Millilitres - **Manufacturer:** DONLAB - **Material:** Glass - **Specification met:** CE ## Images ![CE-250 ASTM STD Glass 250ml 24/40 Joint Single Neck Round Bottom Boiling Flask - Image 1](https://m.media-amazon.com/images/I/41NxYHJKmtL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These are fantastic great price *by P***N on 29 October 2024* Beautiful glaswere for my lab and will be used very soon prober size fit my heating mantel perfectly ### ⭐⭐⭐⭐ Thick glass, durable but doesn’t fit keck clips *by D***N on 7 September 2024* First arrived damaged but seller replaced immediately.
