Clear or amber Type III glass septa bottles come with polypropylene open-top screw caps and 0.125" PTFE®-silicone septa. Clear septa bottles are available only in the 8 oz/250mL capacity. Amber septa bottles are available in 4 oz/125mL and 8 oz/250mL capacities. G.P.I. thread finish for all septa bottles is 24/414.
