The discovery that these bottles can be found on lab ware sites got me wondering about how to find the parts and accessories and to make sure they are compatible. I googled glass stopcock, and I found this great site that has the bottles as well as the stopcock. I thought it would be hard to find a nice glass stopcock with the glass turn key atop the valve just like the ones in the video, but here it is!
As you can see, it is very similar to those seen in that clip. I probably seem like I am "geeking out," as it were, over this. But I just wanted to share this discovery where I was inspired to look for it.
Here are some other relevant items that site has, including the bottles:
tubing connectors (4-7mm)
non-return valve (4-7mm)
where to buy- by country- http://www.scilabware.com/dealers.asp
I could not find any actual tubing on the site, but this one looks like it would be compatible:
(that site also now carries a glass enema bucket of sorts, but I like those bottles!)
Just for the sake of presenting a complete setup, here is a link to the classic silver bullet nozzle!
