If you plan to use an empty disposable-type refrigerant container, be aware that they come with a one-way check-valve incorporated into the shut-off valve. They cannot be refilled. I think this was to prevent folks from converting them to air tanks, but would also prevent using them to recover freon either by condensing it or pumping it.

An empty bar-b-que type propane bottle is another matter. Adapters are available to hook them up to A/C fittings. They cost about $14 or so new, I think, at some discount places such as Sam's. Shops who sell blend-type refrigerants use these to send recovered refrigerants back to the manufacturer for reprocessing.

Special recovery refrigerant bottles are also available, but cost over $50. This is the type used with the recovery/recycling equipment at shops maintaining R12 and R134A equipment.

Good luck.
