Storing Lube

I’m just getting into lubing keyboard parts, progressing from lubing stabilizers to switches now. I have several types of lube but some packages are not very convenient. Some GPL205 for example came in a tube and is very hard to dose when lubing.

I was wondering what a good alternative way is to store lube?

I’ve bought some batches from vendors that came in smaller containers with a twist/pop cap. Is it possible to just empty a tube of lube in a plastic container myself? (a separate one off course)

As for plastic containers, should I pay attention to the type of plastic (or choose glass?) to keep the lube over time without ruining it or changing its characteristics?

All mine have come in containers with screw tops and I just keep them in those in two plastic bags.
