These are tube injectors where a draw-off tube connects the injector to the medication bottle. They are durable and impact resistant with accurate and easy to read calibrations and a metal luer needle mount that won't break like plastic ones.
Three size models are available: 1.0ml fixed dose, and 2ml and 6ml maximum dose.
The 1mL fixed dose injector is a non-adjustable fixed-volume injector set at 1.0 ml for accurate delivery of 1ml vaccines such as Glanvac 6 in 1.
The volumes of the 2ml and 6ml injectors are adjustable with 0.1 ml calibrations from 0ml up to the maximum dose.
