se distilled\sterile water or water that has gone through reverse osmosis.


Items needed:

.22 sterile filter
1ml sterile benzyl alcohol
100ml sterile vial
20ml syringe (the bigger the syringe the more pressure it takes)
Two 18g pins one for drawing water and one for injecting in sterile vial.
small pin 27g for letting air pressure out of vial you injecting benzyl alcohol into

Instructions:

Use a 0.22 syringe filter which will do 100ml of water.
Be sure to add 1ml of sterile benzyl alcohol for every 99ml of water.
Then filter into sterile vial.

The pin used for injecting into the sterile vial and relieving air pressure should stay there with the filter until the process is complete. use the other pin to draw the water with. You will be switching the syringe from the filter to the drawing 5 times or so to get 100ml.

If you wish to make a smaller batch to make 10ml of BW, you would use .1ml of BA and follow the same process as above.
