Standard 3 ml Glass Cartridges for Pens (10-Pack)
Standard 3 ml Glass Cartridges for Pens (10-Pack)
Standard 3 ml (300-unit) glass pen cartridges, sold in packs of 10. Each cartridge arrives individually sealed in its own self-sealing sterilization pouch, with EO and steam sterilization indicators. This is the most common cartridge format in the world: it fits the Gansulin metal pen and any other instrument built for standard 3 ml cartridges. Fill it, seat it, prime it. The cartridge is the only thing you will ever reorder for the pen.
Pick an amount: a 10-pack, or bulk packs of 100, 200 or 400 — the price per cartridge drops as the pack size goes up. Every cartridge is individually pouch-sealed.
Storage: keep cartridges sealed in their pouches in a clean, dry place at moderate room temperature, ideally below 75°F (24°C), away from direct sunlight and high humidity. The pouch is the protective barrier: do not use a cartridge if its pouch is torn, wet or damaged.

STORAGE & HANDLING
Keep cartridges sealed in their individual pouches until use: the pouch is the protective barrier. Store in a clean, dry place at moderate room temperature, ideally below 75°F (24°C), at 30 to 60% relative humidity, away from direct sunlight. High humidity weakens the pouch paper and seal adhesive. Do not use a cartridge if its pouch is torn, wet or damaged.
