Of diatoms and air bubbles

Hi again, yes, the syringe method was my first method!

Thanks John, it looks like the thoughts of some of us, from different countries or continents, focus on similar possible solutions to a given problem! at least, the same gadgets, like the large syringes in this case.
I must say, that the neatness and beauty of your setup and layout of the bench set a high standard!

I do not have bench space for true vacuum pumps, so the syringe is the choice.

Hi Doron,
what I like in your syringe and 3-way-cock method is that you use components that are widely available (if you have contact to people working with them) around the whole world. A method requiring a lucky ebay find is not easy to copy for most people who are interested in the topic.
I think I should go shopping for 100 pcs. packs of syringes and cocks and a new cupboard!

Hi Bob
These large syringes are sold in small packages - 2/pkg sometimes - and the stopcocks are 10/pkg often. See for example:

https://www.ebay.com/p/5x-50ml-Plastic- ... 2981815187
(not sure about the quality of these; Becton Dickinson are excellent, if you can get them in a small package for a low price)

And from Cole-Parmer: "Stopcocks with Luer Connections, 3-way, Male Lock, Non-sterile; 10/Pk"
Perhaps there are cheap Chinese ones on eBay - I did not check.

The syringes and stopcocks are meant to be disposable and can be sterile - I recommend non-sterile, of course. I see that such syringes are marketed for Hydroponics - first piece of equipment to start a home grass plant!!
