Hello members,

Since my endeavors in refining, I have found myself needing supplies and equipment that I may not have at the moment, but I need them now.

Since I am wanting to filter my powders more quickly, than just pouring the solutions through filters, I decided to "test" something.

I took an empty squeeze bottle of ketchup, a bit of 3/8" diameter hose and a syringe and put together a vacuum pump with a container, all in one.

Here's how I did it.

1. I took the hose and inserted in the squeeze bottle from the top where the rubber keeps the ketchup from spilling out, even with the top open.
2. I took a nail, and measured it to the diameter of the nozzle of the syringe, and then I heated the nail with my cigarette light. Once the nail was hot enough, I inserted into the top portion of the squeeze bottle to make a hole in it.
3. I then took the syringe while the hole was still fairly soft, inserted it into the hole until it was tight and snug.

From that point, I inserted the other end of the hose into my solution (I've been working on my sulfuric cell (gold recovery)) down far enough to not disturb the black powder. I then put some clear packing tape around the rim where the hose went into the beaker to keep the hose in place.

After that, I pushed all the air out of the syringe, then I inserted the syringe into the hole I made in the side of the squeeze bottle, then I pulled the syringe to start the flow of the solution, and guess what?... It worked!!!

Below are a few pictures of the setup, but just about any squeeze bottle will work, and any diameter hose, as long as the syringe is wide enough to suck out all the air in one pull to start the flow.

Hopefully this can help someone that might be needing a pump but low on cash. This does work, as I'm currently using it right now.

I just now found out something interesting.

If you don't have a syringe, all you need to do is squeeze the bottle all the way as flat as you can, with the hose in your solution, then, put your finger over the hole that was made for the syringe... then let go of the squeeze hold that you've made and it will start a flow. Immediately after the flow starts, make sure that you take your finger off of the syringe hole you made.

I actually did this by mistake, but after testing it and realizing what I've done, it appeared a syringe isn't needed, IF, the plastic container is flexible enough to be squeezed in then it'll flex back out.

This makes a great homemade siphoning tool.
