Micro M: Stainless - Built with Clean Rooms in mind…

Micro M Designed for Small Batch Inspection

The Micro M is a premium stainless-steel manual inspection unit engineered specifically for clean room environments and designed to support the rigorous visual inspection standards required in pharmaceutical manufacturing. Built with precision and durability in mind, the Micro M provides a contamination-resistant, fully cleanable surface ideal for aseptic operations and controlled spaces.

At the core of the Micro M is its high-fidelity lighting system, delivering 95+ CRI (Color Rendering Index) illumination to ensure exceptional visual clarity and color accuracy. This lighting performance directly supports USP <790> Visible Particulate Inspection requirements, allowing operators to detect even the most subtle particulates, discolorations, or defects with confidence.

Key Features:

Stainless steel construction for superior cleanability, durability, and compliance with GMP clean room standards.
95+ CRI high-intensity lighting, optimized for consistent, true-color visual inspection under USP <790>.
Ergonomic manual inspection design that enhances operator comfort and extended use.
Compact, clean-room-ready footprint ideal for integration into existing inspection workflows.
Configurable options to support specific product types, vial sizes, or operational requirements.

Applications:

The Micro M is ideal for use in:

Clinical Trials: Facilitating rigorous quality control for investigational products in small quantities.
Startup Productions: Supporting new formulations and small-scale manufacturing without the need for large, expensive equipment.
Quality Assurance: Ensuring that products meet stringent standards provided by regulatory agencies.
Stainless Steel: Made with clean rooms specifically in mind.

The Micro M manual inspection unit is designed to address the growing emphasis on visual inspection consistency and compliance within pharmaceutical manufacturing environments. As regulatory expectations for particulate detection continue to increase, manufacturers require inspection stations that support both operator performance and environmental integrity. The Micro M was developed with these considerations in mind, placing equal importance on ergonomics, illumination standards, and material suitability for clean room use.

Clean Room Construction and Design Considerations

The unit’s stainless-steel structure is not simply a durability feature—it reflects the operational reality of clean room production spaces, where equipment must withstand repeated sanitization cycles, resist corrosion, and minimize the risk of contaminant retention. Stainless steel provides a smooth, nonporous surface that aligns with GMP cleanability requirements and reduces the likelihood of particle generation. Additionally, the compact design of the Micro M allows it to integrate into existing inspection workflows without contributing to unnecessary clutter or turbulence within controlled environments.

Role of High-CRI Lighting in USP <790> Compliance

A defining component of the Micro M is its 95+ Color Rendering Index (CRI) lighting system. While brightness is often emphasized in visual inspection setups, CRI plays an equally important role. A high CRI value enables light to reproduce colors with greater accuracy, which directly affects an operator’s ability to perceive subtle particulate movement, vial defects, discoloration, or product variation.

Under USP <790>, operators must be able to reliably detect visible particulates in injectable products. Lighting that distorts color or shadow contrast can compromise this task. By providing high-fidelity illumination, the Micro M helps create more uniform inspection conditions and reduces variability caused by environmental lighting differences or operator fatigue.

Supporting Operator Performance in Manual Inspection

Despite increasing automation, manual inspection remains widely used—particularly for small batch production, complex product types, and investigational materials. In these contexts, operator comfort and consistency are critical. The Micro M incorporates ergonomic considerations such as appropriate viewing angles and operational posture to reduce strain during extended inspection sessions. The goal is to enable operators to maintain attention and acuity without unnecessary physical fatigue, which can influence defect detection rates.
