EISCO Specific Gravity Bottle, 50ml - Flat Bottom with Perforated Stopper - Borosilicate Glass Labs

bien empacado, buena calidad

I needed this for a school project and this was the only vendor offering exactly the bottle style at a price below, like, $100. I found this product incredibly difficult to source anywhere else. It's effectively a glass bottle so, in that sense, I feel it's hard to go wrong. It arrived unbroken.That said, this is meant to be a precision instrument and since I didn't need to be absolutely precise with my experiment, I can't attest to its capabilities there. I have no idea if the bottle was manufactured precisely to its proclaimed 50 mL volume, for example. The one thing I can offer here is that the bottle comes with a ground glass stopper so it fits snugly in the bottleneck, preventing air or any other contents from escaping, save through the hollow centre of the stopper.
