Oil cartridges are used for herbal concentrates. They are normally 1mg or.5mg capacity. Oil tank cartridges or cartomisers are used on a number of Oil Batteries, here at Mig Vapor we carry many of the batteries for these tanks. This type cartridge has became the standard for vaping oils. Source: www.migvapor.com/vaporizers/oil-cartridge-510
