Specifications

Key Features

Clear Glass Design: The transparent glass barrel provides full visibility of the contents inside. This allows researchers to monitor fill levels at a glance and visually inspect the solution for clarity, particulate matter or discolouration before each use.

Individually Sealed: Every cartridge in this Cartridges (20-Pack) arrives in its own sealed sterilisation pouch. This protects each unit from contamination during storage and confirms sterility at the point of use.

Universal Pen Compatibility: Built to standard 3ml cartridge dimensions, these cartridges are compatible with V1, V2 and V3 reusable pen systems, including the Signature Peptides Injector Pen Kit. They also fit other cartridge-based injector pens that accept the same standard sizing.

Clean Replacement Option: Ideal for laboratory, research, training, demonstration or cosmetic preparation use. Each cartridge is a practical single-fill replacement that keeps your pen system hygienic and ready for the next protocol cycle.

How to Fill a Cartridge?

Use a disposable measuring syringe to draw reconstituted solution from your research vial. Transfer the solution into the cartridge through the open end, then load the filled cartridge into your pen body. Prime the pen before first use by dialling 1 to 2 units with the needle pointing upward and pressing until a drop appears at the tip.

Measuring syringes are included in the Signature Peptides Injector Pen Kit. If purchasing cartridges separately, ensure you have a suitable syringe for the filling step.

Storage Guide

Store unused cartridges in their sealed sterilisation pouches at room temperature in a clean, dry environment away from direct sunlight. Once filled with reconstituted peptide solution, store the loaded cartridge at 2 to 8 degrees Celsius. Do not freeze filled cartridges.
