Overview
The HunterLab UltraScan VIS Accessory Kit is a comprehensive modular system engineered to extend the measurement versatility of the UltraScan VIS benchtop spectrophotometer—a precision d/8° integrating sphere spectrophotometer designed for CIE-compliant colorimetric analysis in research, quality control, and regulatory environments. Built upon a pulsed xenon lamp illumination source and a 360–780 nm spectral acquisition range with 10 nm bandwidth, the UltraScan VIS delivers high photometric stability and low inter-instrument agreement variability. This accessory kit enables rigorous, standardized color measurement across diverse sample forms—including opaque solids, translucent films, viscous pastes, granular powders, and low-volume liquids—without requiring instrument reconfiguration or recalibration. Each component is mechanically and optically validated to maintain traceable path-length geometry, beam uniformity, and port coverage integrity per ASTM E308, ISO/CIE 11664, and USP guidelines.
Key Features
- Modular, field-installable accessories fully compatible with UltraScan VIS firmware v5.0+ and EasyMatch QC software
- Optical alignment-certified components ensuring consistent illumination geometry and detector response across all measurement modes
- Traceable mechanical tolerances: ±0.1 mm positional repeatability for sample positioning fixtures
- Non-contact, non-destructive sample handling architecture minimizing operator-induced variability
- All metal and anodized aluminum components meet ISO 14644-1 Class 8 cleanroom compatibility standards
- Integrated light-trap design in reflection holders and transmission cells to suppress stray light contributions
Sample Compatibility & Compliance
The kit supports compliant measurement of heterogeneous materials under controlled geometric conditions. The adjustable reflectance stand accommodates cylindrical samples (15–40 mm diameter) with ≥50 mm exposed length above thread features—ensuring full port coverage and eliminating edge diffraction artifacts. The compression clamp applies uniform axial force (1.2–1.8 kPa) to fiber bundles, producing reproducible packing density for textile and nonwoven color evaluation per AATCC Test Method 173. The micro-powder test kit enables reflectance measurement of ≥0.4 cc volumes using a white PTFE plunger and calibrated cavity depth—validated against NIST SRM 2009a for spectral reflectance consistency. Flow cells (10/20/50 mm path lengths) and rectangular transmission units comply with ASTM D1003 for haze and transmittance, while the overflow tray ensures meniscus-free liquid fill for accurate Y, x, y tristimulus computation. All accessories are referenced in HunterLab’s IQ/OQ documentation package for GLP/GMP audit readiness.
Software & Data Management
All accessories operate natively within EasyMatch QC v5.2+ and are auto-detected via hardware handshake protocols. Measurement methods—including “Powder Reflectance (Micro)”, “Liquid Transmission (Flow Cell)”, and “Film Total Transmittance”—are preconfigured with appropriate illuminant/observer settings (D65/10°, A/2°), aperture corrections, and averaging parameters. Audit trails record accessory ID, mounting orientation, and calibration verification timestamps per FDA 21 CFR Part 11 requirements. Data export supports CSV, XML, and industry-standard CxF/XRGA formats for integration with LIMS and ERP systems. Optional HunterLink API enables real-time accessory status monitoring and method validation logging.
Applications
- Pharmaceutical solid-dose color release testing (USP , EP 2.2.57)
- Food powder consistency verification (e.g., spices, dairy blends, infant formula)
- Plastic resin pellet batch-to-batch color matching in extrusion QC
- Coating film transparency and yellowness index (YI E313) assessment
- Chemical process stream color monitoring via flow cell integration
- Medical device polymer tint verification under ISO 10993-12 biocompatibility frameworks
FAQ
Are all accessories shipped with calibration certificates?
Yes—each optical component (flow cells, transmission units, and reflectance stands) includes a NIST-traceable dimensional certificate and spectral reflectance verification report.
Can the micro-powder kit be used with non-HunterLab spectrophotometers?
No—the kit’s mechanical interface, port alignment, and software-defined measurement protocol are exclusive to UltraScan VIS instrumentation.
Is the flow cell compatible with aggressive solvents such as THF or chloroform?
Standard flow cells use borosilicate glass and Viton O-rings; chemical resistance data sheets are available upon request for specific solvent exposure durations.
Does the transmission overflow tray support automated liquid dispensing systems?
Yes—it features standardized mounting holes and leveling feet compatible with third-party autosamplers meeting ANSI/SLAS footprint specifications.
How often must the white calibration tile be replaced when using the compression clamp?
HunterLab recommends quarterly verification against a master tile; replacement frequency depends on usage intensity and environmental particulate load—typically every 12–18 months under ISO 8 cleanroom conditions.
