I buy Roundup in premixed 5-liter hand-pump sprayer:

I use the concentrate. It is hugely less expensive purchased that way.

I don't use enough roundup to make it a real concern. I don't have a
lot of area (on a sq. footage basis) to nuke of all plant life. Due to
political retardation, concentrated roundup is not available at the
retail level where I am.

The pump sprayer is easily refillable.

You can buy concentrated roundup that comes in a pump sprayer?
