Q2 Cartridges

Bio Pen Q2 cartridge buying guide
Match your Bio Pen Q2 device label, connector shape and pin count before adding cartridges to cart. Pin count alone is not enough because different device families can use different locking shapes.

Connector shape: compare the underside tabs and lock position before opening a sealed pack.
Pin count: Q2 buyers usually compare 9, 14 and 25 pin tips. Confirm the Bio Pen Q2 model label before opening the pack.
Single-use sterile reminder: use a fresh sealed cartridge for each session and do not reuse opened tips.
Shipping and returns: tracked shipping is available to the US, Canada and Australia; unopened wrong-model items follow the posted return policy.
