hey guys - quick help needed here.
I 'spose I only remove the small round mid-section of the alloy cap and go with the needle straight through the rubber cap to draw out into syringe - right?
You guys usually cover the rubber midsection again thereafter or is it safe to be kept like that? 10ml vial in fridge?
scuse if my Q's seem daft but I've only used the 1ml amps before.
