Pen Recon Helper - various colours (SKU: PRH)

Recon Helper (for pen cartridges)

The Recon Helper is a compact 3D-printed tool designed to simplify filling 3ml pen cartridges in the lab.

It securely holds the cartridge upright during filling for stability and features an integrated section that lets you gently push the rubber plunger upward (with venting needle in place) to expel excess air pockets cleanly and safely.

**Please note that the contents can squirt out if pushed up too high, so be sure to stop pushing the plunger upward well before the liquid meets the venting needle tip!

A simple, practical aid that makes cartridge reconstitution smoother.

**Just a quick heads-up! 3D printing is a bit of a dance between a human and a machine. Because each piece is made layer-by-layer, tiny unique marks or slight surface variations are totally normal. We think these 'birthmarks' give each item character! However, if you’re looking for a factory-molded, flawless finish, our 3D-printed goodies might not be the best fit for you.
