Reusable Metal Injection Pen (V3) 3ml

The Reusable Metal Injection Pen 3ml (version 3) is a premium, durable pen device designed for repeated use with compatible standard 3ml glass cartridges and screw-on pen needles. Manufactured from lightweight aluminium alloy, it provides a more robust and premium alternative to disposable or plastic injection pens while remaining compact, portable and simple to operate.

Featuring an adjustable 0–60 unit dose mechanism with 1-unit increments, the pen allows controlled, repeatable dispensing from a compatible 3ml cartridge. The mechanical adjustment dial provides positive click positioning, while the clear dose display makes the selected setting easy to read.

Unlike disposable pen devices, the metal pen body can be reused by simply replacing the compatible cartridge when required.

Reusable Metal Construction

The aluminium alloy body has been designed to provide improved durability compared with standard plastic pen devices. Its solid construction gives the pen a premium feel while remaining lightweight enough for convenient everyday storage and transportation.

Once a cartridge is empty, the pen itself does not need to be discarded. A new compatible 3ml cartridge can be fitted, allowing the device to be used repeatedly.

0–60 Unit Dose Adjustment

The integrated mechanical dial can be adjusted from 0 to 60 units in 1-unit increments. Each adjustment provides positive click positioning, with the selected setting displayed through the dose window.

The dial can also be adjusted in either direction, allowing the selected setting to be corrected before use if required.

Cartridge & Needles Not Included

Please note: This product is supplied as the empty reusable metal injection pen device only.

3ml glass cartridges are NOT included and must be purchased separately. Compatible pen needles are also sold separately unless specifically stated otherwise.

For convenience, compatible 3ml Sterile Glass Pen Cartridges and Pen Needles are available separately from our store.

Important

Always check cartridge and pen-needle compatibility before use. Follow appropriate sterile handling procedures when filling or replacing cartridges and use a suitable sharps container for the disposal of used needles.
