Dual-Chamber Architecture • On-Demand Mixing • Optimized for Peptides & lyophilized formulations
The 4mL Double Chamber Injection Pen is an advanced mixing-and-delivery device engineered for medications requiring two-phase preparation, such as lyophilized powders combined with diluents. This pen integrates two independent chambers inside the cartridge system, allowing safe and efficient activation, mixing, and administration within a single pen.
Designed for pharmaceutical companies, aesthetic clinics, peptide therapy centers, and wellness programs, this injection pen supports precise dosing, on-demand reconstitution, and smooth subcutaneous injection—greatly improving workflow efficiency and reducing contamination risk.
Featuring a clean, medical-grade white body, this pen includes a transparent dual-chamber cartridge compartment, a dose display window, and a stable injection drive system. The pen also adopts a twist-activation mixing mechanism, enabling users to release the diluent into the powder chamber immediately before use, ensuring optimal drug stability and potency.
Its 4mL total capacity makes it ideal for peptides, aesthetic formulations, regenerative medicine compounds, and other two-phase injectable preparations.
Ideal for medications requiring reconstitution
Powder and liquid remain fully separated until activation
Supports better stability, reduced degradation, and longer shelf life
Mixing occurs inside the pen — no additional mixing tools required
Twist or push activation releases the diluent to the powder chamber
Ensures freshly mixed solution immediately before injection
Reduces contamination risk and simplifies clinical operation
Suitable for peptides, growth factors, regenerative compounds, GLP-1 variations, or multi-dose programs
Transparent chamber allows clear visibility of contents and mixing status
Controlled injection pressure
Stable mechanical plunger for consistent dose delivery
Low-resistance injection suitable for sensitive medications
Lightweight polymer body for easy handling
Matte white finish for professional clinical appearance
Enhanced grip area for safe operation
Supports standard pen needles including:
31G / 30G / 29G (4mm–12mm)
