GL45 caps/lids for media bottles - why so expensive & where to get?
I've done some searching and was astounded at the price for some of these. One cap was listed for $32 on ebay and it wasn't even PTFE or anything
spoecial, normal blue PP. I think they were hoping some sucker would see it and think he was getting a case b/c he said that "these come in cases"
but that he sells them individually (further down in the post..)
The prices can vary greatly from about $1.40 (for like 40-60 quantity) to $3-8 each for some more specialized ones - fancy colors - not special
material, just differnet colors!
In many cases I've found other bottle caps to fit bottles they weren't meant for, and they often work fine for certain things like holding powders or
liquids that don't need a perfect seal.
I have about 3 dozen bottles with no lids and i'm not spending $100+ for the lids alone!
Does anyone know if there are any products that come with a cap that is the same thread and size as the media bottles
here are the bottles I'm talking about

Lake Charles Manufacturing sells 100 mL media bottles with GL-45 caps for in lots of 30 for around $64. That is likely the cheapest you are going to
find.
I have around 20 GL-45 media bottles, and I like them, but they aren't cheap, especially if you want the PTFE-lined caps (and who doesn't).

That is insane (the price!!) I wonder what kind of caps they are. I picked up a huge auction of 500ml and 1L order of brand name bottles, all new,
but without caps, except about 10 of them.
I'd still like to find some alternative caps that would fit.
I also have some test tube like vials that is about the same size as a normal 2L pop bottle lid (they press on and seal, but not screw on, different
threads). I need about 100 of these lids but can't seem to find them ATM but it hasn't been my #1 priority)

That site has some good prices on equipment as well! Some flasks are as cheap as those from china!

I have some decent quality white media bottle caps, which are lined with some Teflon type material. They are better than the cheap blue caps for
sure. I would be willing to sell what I have left (about 10 or so) for $2 each, if you want to try some. I have used them for years with no
problem. A few others here have used them with great luck. I would also swap caps for smaller media bottles, if you wish, like 100, 250, or 500
ml sizes.

Can confirm that those white caps are great. I have several of them and have used them for HCl
and bromine without issues. Come to think of it, if you still have some when I make my next order, I'd be interested. Making a mental note.

Those white caps are definitely decent. The cheap blue caps probably won't hold up against nitric acid or DCM for very long, but Dr. Bob's white caps
can.
