Specifications

A dual-chamber pen, built to be specified.

The DS01 holds two separate drug components — a liquid and a freeze-dried solid — in a single dual-chamber cartridge. The patient rotates the dose ring to bring them together, mixing them in-line. The drug remains freeze-dried until this moment, so the shelf life of the formulation is extended and the closed system minimizes contamination. After mixing and priming, a single press delivers the full dose.

Why customers choose it

A two-component pen, in one closed system.

True dual-chamber platform

Two drug components (liquid and freeze-dried) mixed in-line, with no external mixing step.

Extended shelf life

The freeze-dried component stays stable until the moment of injection.

Closed, low-contamination system

A single sealed device from storage to injection.

Single-use by design

One pen per dose; no cleaning, no cross-contamination.

Clear feedback

Dose scale, rotation prompt sound, and dose-progress window confirm every step.

Wide application

Suitable for insulin, GLP-1, peptides, and other subcutaneous two-component biologics.

Patient workflow

Five steps, every time.

1

Attach a needle

Remove the cap and screw on a new pen needle.

2

Mix the two components

Rotate from Position A to Position B; a click confirms mixing is complete.

3

Prime and clear air

Pull the plunger and rotate to Position C; a click confirms the line is clear.
