Glass Cartridge – 10 Pack (3ml)

3ml Sterile Glass Cartridges (10-Pack) for V1, V2 and V3 Pen Systems

The Signature Peptides Cartridges (10-Pack) contain ten individually sealed, pre-sterilised 3ml glass pen cartridge vials. Each cartridge is manufactured to ISO-certified standards and arrives ready to fill with your chosen solution. This is the standard refill pack for researchers who use a reusable injector pen regularly and want a reliable, clean replacement supply without overcommitting to a larger quantity.

Specifications

Precise Filling and Controlled Dispensing

Each cartridge in this (10-Pack) holds up to 3ml, making it suitable for precise filling and controlled dispensing applications. A single 3ml cartridge provides approximately 300 units. At a common research dose of 10 units per session, one cartridge covers around 30 sessions – so ten cartridges supply roughly 300 sessions of consistent use.

The clear glass barrel allows easy visibility of contents at every stage, from initial fill to final dose. Researchers can monitor solution levels, check for clarity and confirm there is no particulate matter before each use. When a cartridge is fully dispensed, replace it with a fresh sealed unit from the pack for a clean, practical changeover with no downtime.

Compatible Pen Use

These cartridges are designed for cartridge-based injector pens. They fit V1, V2 and V3 reusable pen systems, including the Signature Peptides Injector Pen Kit. The standard 3ml sizing also works with other cartridge-based pens that accept the same dimensions – check your pen sizing and compatibility before purchase.

How to Fill and Load

Each cartridge is supplied empty and ready for the user to fill. Use a disposable measuring syringe to draw reconstituted solution from your research vial, then transfer it into the cartridge. Load the filled cartridge into your pen body, attach a pen needle (32G x 4mm recommended), prime by dialling 1 to 2 units with the needle pointing upward and press until a drop appears at the tip.

Storage and Handling

Keep sealed cartridges at room temperature in their original packaging until ready to use. Avoid heat, direct sunlight and moisture. After filling with reconstituted solution, refrigerate the loaded cartridge at 2 to 8 degrees Celsius and use within the timeframe recommended by the solution supplier. Do not freeze filled cartridges. Discard any cartridge with a damaged or pre-opened seal.
