Received some discretely packaged prop (60ml) but the lid pops off and so to transfer the gear into sterile vials, it will have to be exposed to air. Is this a big deal.

Unaware that it would arrive like this, I preloaded three syringes straight from the open-lid container of prop. The gear touched nothing but it was exposed to air.

I had 20mL sterile vials overnight shipped and will have to use my 3ML syringes to make multiple transfers. If I'm cautious not to let the oil be exposed to anything but air, is there reason for concern?

Anyone else have experience or tips with this?
