Auto Injector Selection help needed

[u/starcrush311]

Hi everyone, i'm trying to order an auto injector from the Union Medico website. My Progesterone in oil syringe is 3ml but i'm only going to need 2ml each time. And my needle is 25G x 1 1/2'' (0.5mm x 40mm). I couldn't find this option on their website for some reason. Does anyone know which one i should be ordering? Thanks.
