1: they are rounded bottoms (like some men i know )
2: i dont want plastic..they will stain ( like some men i know)
know the feeling....when i'm rinsing out 16 test tubes every morning.I have a syringe ... okay, I need to go and have another look on amazon and ebay... but possibly tomorrow now, starting to feel a bit too achy to care about test tubes today.
Thanks guys
