vials and tops?

[lemonskunk]

i am currently undergoing a fina conversion of about 10g, i am a little confused though. i need to split the tren up into multiple vials and dont know the correct measurements to use for the seals/tops in relation to the mouth of the vials.

i have found a site that provides reasonably priced vials at a reasonable amount (i dont need 144 vials). the mouth opening of this vial is 16mm. the tops they sell are either 13mm(not going to work) or 20mm. im assuming that i need the 20mm tops but i dont want to make a mistake. any help would be excellent. thanks in advane

20mm vials are the standard in which you'd need 20mm stoppers and 20mm crimptops. Do you have a crimper? If not you need to buy pre sealed strerile vials
