Eisco Labs Large Acrylic Bell Jar 12" height x 7" diameter

Seems like a perfectly good vacuum bell jar with opening for bung (same size as smaller one sold by Eisco).The beware is for the diameter same as smaller Eisco jar, all Eisco jars specify inside diameter at the bottom of the jar but they appear to taper inwards beyond a few inches. This may not matter to you BUT if size really does matter just beware it is about 0.5 - 0.75" smaller as you go up well before the expected dome of the jar. I'm keeping, but means a whole load more time shoehorning to fit in available space.
