Gansulin Metal Reusable Pen (1-60 Units, 3 ml Cartridges)

The Gansulin pen is an all-metal, dial-a-dose instrument for standard 3 ml (300-unit) glass cartridges. Where the market default is disposable plastic, this is a machined metal chassis built to be kept: one audible, tactile click per unit, from 1 to 60 units per dispense, with a dose window you can read at a glance.

• Dose range: 1 to 60 units per dispense, in 1-unit (0.01 ml) increments
• Cartridge format: standard 3 ml / 300-unit glass pen cartridges. No proprietary consumables, no lock-in
• Overdraw interlock: the dial physically stops when the set dose exceeds what remains in the cartridge
• Dial-back correction: set too much? Turn the knob back. The dose corrects downward without dispensing a drop
• Needle interface: standard screw-thread pen fitting (needles not included or sold)
• In the box: pen and zip case. Genuine, factory-sealed, direct-sourced units
