What’s included:
Please note:
No medication, peptide solution or pen tips are included. This product is supplied empty and is intended for research and laboratory applications only. Always confirm the compatibility of cartridges and accessories before use.
Each order includes: Pen body, cartridge holder, pen lid and 3ml cartridges
These pens are compatible with most universal needle tips and standard 3ml refill cartridges. We stock both cartridges and pen needles separately - shop them below.
Applies to Disposable pens only:
Before you start
Do not twist the dial and press the plunger down before the pen is assembled — once pressed, the plunger cannot be wound back up.
Assembly
Filling the cartridge
Always ensure the cartridge is secured inside the cartridge holder, and the cartridge holder is clicked onto the pen body before filling. Filling without the cartridge properly supported creates excess air pressure, which can cause the rubber stopper to eject.
