4-Cartridge Purge Holder - Holds 4 x 3ml Pen Cartridges

Cleaner fills. Better control. Secure storage. The 4-Cartridge Purge Holder keeps four 3 mL pen cartridges upright and steady while you work, with a built-in center purge button that helps push trapped air out for smoother, more accurate fills.

Why it works

Every cartridge drops into its own slot so nothing tips, rolls or knocks together while you fill. The raised center pad gives you a solid place to purge, and the compact footprint tucks into a drawer, a fridge shelf or straight into your kit. Made to order and printed in the USA.
