With real end caps.

I have seen a few "cheaper" Pyrex tanks but they suck.   They don't have real end caps,  they have stoppers which are a PITA.    The tube itself is $5.00 and your choice of end caps for $14.00.  They have a large variety of end caps including 3 different types of metal caps (which are more expensive).

They also have a huge assortment of other Pyrex styles that are more expensive if you need want more style.  The combinations of end caps / tanks are pretty endless.
