Metal Reusable Auto Pen V3

Precision Cartridge Delivery System | Durable Aluminum Alloy Construction & Adjustable Dosage Dial

Overview:
The Metal Reusable Auto Pen V3 is a premium, heavy-duty delivery device engineered for precise, smooth, and repeatable subcutaneous administrations. Compatible with standard 3mL cartridge systems, this pen features an ultra-durable anodized aluminum body, a smooth spring-loaded plunger mechanism, and a high-precision dosage selector with click-stop volume control.

Designed for longevity and environmental efficiency, the V3 eliminates single-use plastic waste while offering researchers and users a reliable, ergonomic tool for continuous peptide protocols.

Standard disposable insulin/peptide pens rely on flimsy plastic housing that wears out quickly and leads to dosing inaccuracies over time. The Metal Auto Pen V3 upgrades your setup with aircraft-grade aluminum alloy housing built for years of daily use.

Featuring a clear dosage window and an tactile increment dial, it guarantees exact unit selection down to fractional measurements. Its ergonomic weight distribution ensures maximum stability during injection, eliminating hand-shake and optimizing user comfort.

• Aircraft-Grade Aluminum Alloy: Built to withstand daily wear, travel, and accidental drops without cracking or losing calibration.
• Universal 3mL Cartridge Fit: Fully compatible with standard 3mL glass cartridges and standard pen needles (compatible with 31G/32G micro-needles).
• Micro-Dose Precision Selector: Tactile click-stop dial ensures exact unit selection with clear visual feedback through the display window.
• Smooth Spring-Drive Plunger: Delivers consistent, low-force fluid injection for minimal tissue disruption and comfortable administration.
• Reusable & Eco-Friendly: Replaces hundreds of disposable pens, offering a cost-effective, sustainable long-term solution.

1. Loading the Cartridge: Unscrew the pen body from the cartridge housing. Insert a filled 3mL cartridge (rubber stopper facing the plunger) and screw the housing securely back into place.
2. Attaching the Needle: Peel the seal off a standard single-use pen needle and screw it firmly onto the threaded tip of the cartridge housing.
3. Priming the Pen: Dial 1 to 2 units, hold the pen pointing upward, tap the cartridge gently to push air bubbles to the top, and press the injection button until a small drop appears at the needle tip.
4. Dialing Your Dose: Turn the rear dial to your exact calculated unit dosage indicated in the window.
5. Administration: Insert the needle subcutaneously at a 90° angle, press the push button completely, and hold for 6 to 10 seconds to ensure full volume delivery before withdrawing.

• Wipe the exterior with an alcohol prep pad or damp microfiber cloth between uses.
• Do not submerge the pen mechanism directly in water or autoclave the main metal housing.
• Always store with the protective pen cap securely fastened and remove the disposable needle after each injection to maintain cartridge sterility.
• Store in a cool, dry place alongside your refrigerated cartridges.
