Your cart is empty.These single-use 16x100mm PYREX disposable round bottom culture tubes are packaged for your convenience in easy-to-open, easy-to-use bulk packs. They hold approximately 15mL and are made of borosilicate glass to reduce pH changes and contaminants potentially leached from soda-lime glass.

They were thin and very easily broken, Pyrex used to be a nearly unbreakable not very long ago but now it's just like thin ordinary glass, its honestly not a quality product as advertised. Very dissatisfied with my order of 250 Pyrex tubes

Awesome product. I got these to help improve my glass art skills without having to worry about wasting my inventory of more expensive materials. Product arrived very quickly! Only suggestion I have is that it would be nice to include a photo of the thickness of the glass. Your products are great and I would hate to see you get a negative review due to customers expecting something different than what they received.
