Can you reuse solutions?

Yes a couple of times but I wouldn’t pour it back in the bottle if you’ve used it already. For example I have 3 ph meters so I’ll put some of each in a cup and use the same solution to calibrate all 3 of my ph meters then toss the solution. The bottles last a long time though.

The bottle doesn’t specify how much solution to add to how much water to make the ph 7.0 and 4.0 solutions. It just says add the required amount???

You don't add anything its pre made to the ph level.

Can i use this solution for other brand ph meters ? i own a adwa ph meter, or is this only for bluelab products ?

It will work for all PH meters.

How often would I expect to run out of solution? I would hope for $45.00 this would last a t least a year.

I believe it will last a year I Calibrate my pen whenever it goes out of calibration which is usually about once a month
