Single-use · Spring-Loaded · Constant Thrust
A single-use, spring-powered auto-injector with constant-thrust delivery and no battery. One press by the patient — a built-in energy-storage drive delivers an even, uninterrupted dose, built for high-dose, high-viscosity biologics. Fully customizable, from dose window to dose scale, with one supply chain: pen, cartridge, needle and carton.
Intended applications, dose ranges and all clinical statements are determined by the final registered labeling for each market. Specifications are subject to change without notice.
Match your brand, your drug and your dose plan on a ready-to-market auto-injector — with end-to-end development, performance verification and registration support.
Custom body and cap finishes — white, blue, cream, or your own.
The transparent display window, printed with your unit of measure (mg, IU or mL) for at-a-glance reading.

Screen-printed brand logo and product label on the barrel.
Custom color on the cap, body, clip and dial to code drug type.
Dose range and thrust engineered to your formulation.

Stable, even injection of thick, high-dose, high-viscosity formulations.
An intuitive dose-lock and easy-scroll dial reduce the patient's operational burden.
