Lab 25ml,24/40,Single-Neck,Round Bottom Glass Flask,1 Neck,Laboratory Boiling Vessel

Good quality, no issues with its use. As good as other higher priced flasks out there.

This is my favorite 1L rbf, now 😊

This flask arrived in good condition and feels well made right out of the box. The glass has a nice clarity to it, so it’s easy to see inside, and the thickness gives it a reassuring feel when handling it. The ground joint is clean and smooth, which makes connecting it to other pieces straightforward. It seats properly without needing extra force and feels secure once in place. That makes setup feel more predictable without needing to fuss with alignment. The round bottom is evenly shaped and balanced, so it sits well in a clamp or holder without shifting around. The overall shape looks uniform, and there aren’t any noticeable defects or uneven areas in the glass itself.

This is the only place that even had a 150 flat bottom boiling flask. Good products. Deschem is a good choice!

Came with a few cracks in the glass, the worst being on the ground female joint which makes heating from below, as well as clamping in a stand a bit worrisome. However, I haven't had any issues with my purpose for it. Maybe consider something more reliable if planning onĥh cold shocking or applying intense heat directly. Shipped from China if I remember correctly. Didn't take too long.

things are always late and mostly broken. They also make it hard for you to be refunded.

24/40 is correct which was my big concern.

Always great packing best Chinese lab glass available packed in foam every time great company worth the wait
