Engineered to ISO 11608 Standards

The ISO 11608 series is the cornerstone of international regulatory requirements for needle-based injection systems (NISs). Our disposable pen injector is designed in full accordance with this comprehensive standard, which defines functional and test requirements for pen injectors, including mechanical and electronic performance tests.

Specifically, the pen is compatible with:

ISO 11608-3: Defines requirements for 3ml cartridges used in needle-based injection systems
ISO 11608-2: Covers specifications for double-sided pen needles

This standards-based approach ensures seamless integration with existing pharmaceutical supply chains and fill-finish operations. Pharmaceutical partners can confidently pair this pen with their preferred cartridge and needle suppliers, knowing that compatibility is validated against internationally recognized benchmarks.

Dose Accuracy and Mechanical Reliability

The pen incorporates a proven gear-shift and dose-control mechanism that delivers consistent, reliable dosing. Key performance characteristics include:

Precision Dosing: 1 IU increments enable fine-tuned dose titration—critical for therapies requiring gradual adjustment, such as GLP-1 agonists
Audible and Tactile Feedback: Users receive confirmation during dose dialing and injection, reducing the risk of administration errors
Dose Correction Capability: The dial mechanism allows for dose adjustment before injection
Stop-Last-Dose Feature: Prevents dialing beyond the remaining volume in the cartridge

Well-designed injection pens deliver uncompromising accuracy through ISO 11608.1-certified mechanisms that maintain dosage errors below ±2%. This level of precision is particularly vital for biologics and peptide therapies where dosing accuracy directly impacts therapeutic outcomes.

Biocompatible Materials and Patient Safety

All patient-contacting and drug-contacting components are manufactured from medical-grade thermoplastics that undergo rigorous biocompatibility assessment per ISO 10993-1. Commonly used medical-grade materials such as cyclic olefin polymers (COPs), polycarbonate (PC), and medical-grade polypropylene (PP) are selected for their proven safety profiles and regulatory compliance.

Key Material Safety Considerations:

Biological Evaluation: Cytotoxicity, sensitization, and systemic toxicity testing per ISO 10993-1
Chemical Compatibility: Extractables and leachables (E&L) assessment to prevent drug-material interactions
USP Class VI Compliance: Materials meet the most stringent biocompatibility classification for medical devices
Sterilization Resilience: Components withstand gamma, e-beam, or ethylene oxide sterilization without performance degradation

The FDA requires a human factors assessment as part of new drug applications for injection devices, ensuring that user interface design minimizes use errors and maximizes patient safety. Vialab’s design philosophy incorporates human factors principles from the earliest stages of development, resulting in a pen that is intuitive, accessible, and safe for diverse patient populations.

Adjustable Dose Design: Empowering Patient-Centric Care

The shift toward home-based care and patient self-administration has fundamentally changed how drug delivery devices are designed. The self-administered parenteral market is valued at USD 21.6 billion in 2025 and is projected to grow at a CAGR of 6.3% to USD 37.4 billion by 2034. Patients managing chronic conditions increasingly require devices that are intuitive, reliable, and comfortable.

Why Adjustable Dose Matters

The 1–60 IU adjustable dose range of our pen injector addresses several critical patient needs:

Titration Flexibility: Many therapies—particularly GLP-1 receptor agonists—require gradual dose escalation to minimize side effects and optimize therapeutic response
Personalized Treatment: Patients can adjust doses based on clinical response, blood glucose levels, or other biomarkers
Reduced Waste: The ability to dial precise doses minimizes medication waste compared to fixed-dose devices
Enhanced Adherence: Studies show that 94% of type 2 diabetes patients report eliminated dosing anxiety when switching from vials to injection pens

Accessibility Features

The pen is designed with diverse patient populations in mind, including elderly users and those with visual or motor impairments:

Large, High-Contrast Numbers: Good readability even for visually impaired patients
Audible Feedback: Clicks during dose dialing and injection confirm proper operation
Ergonomic Design: Comfortable grip and short stroke of dose setting element, even at the highest selectable dose
Intuitive Operation: Simple dial-and-inject mechanism minimizes training requirements

The System Approach: Pen, Cartridge, and Needle Compatibility

An injection pen is not merely a standalone product but a sophisticated drug delivery system comprising the pen, cartridge, and needle. The compatibility of these three components directly determines dosage accuracy, injection safety, and patient experience.

Cartridge Compatibility

Our pen is engineered for use with standard 3ml cartridges compliant with ISO 11608-3. The cartridge serves three critical functions:

Medication Containment: Glass or plastic body maintaining drug stability
Sealing Protection: Rubber piston, aluminum cap, and septum preventing leakage and contamination
Sliding Delivery: Piston movement within the cartridge enabling precise drug expulsion

The pen’s thrust characteristics—typically delivering peak force between 8-15N—are optimized for smooth, consistent cartridge actuation. A well-designed injection pen maintains stable thrust throughout the entire dose range, with variation not exceeding ±15%.

Needle Compatibility

The pen is compatible with ISO 11608-2 double-sided pen needles. Standard pen needles feature a universal fit and are compatible with all major pen devices. This flexibility allows pharmaceutical partners to select needles that best suit their drug formulation and patient population—whether standard needles or safety-engineered options.

Therapeutic Applications

The 3ml / 60IU Disposable Pen Injector is suitable for a broad spectrum of subcutaneous therapies:

Therapeutic Area	Examples
Metabolic Disorders	Insulin, GLP-1 agonists (semaglutide, tirzepatide, liraglutide)
Hormone Replacement	Growth hormone, testosterone, FSH
Autoimmune Conditions	Interferon, TNF inhibitors, other biologics
Peptide Therapies	Various peptide-based medications
Fertility Treatments	Reproductive hormones

GLP-1 Therapies: A Growing Opportunity

GLP-1 receptor agonists are revolutionizing the treatment of both Type 2 diabetes and obesity. Approximately 5% of US adults (about 12.5 million people) have used or are currently using GLP-1s for weight loss alone. However, more than half of users discontinue treatment within months—a challenge that well-designed delivery devices can help address.

Our pen injector addresses key barriers to GLP-1 adherence:

Clear Titration: 1 IU increments support gradual dose escalation
Ease of Use: Intuitive operation reduces injection anxiety
Visual and Auditory Feedback: Confirms proper dose delivery
Compact Design: Portable for daily use and travel
