Spectrophotometer

Spectrophotometer Instruments for Industrial Material Testing

Our range supports material testing and quality control across plastics, packaging, coatings, textiles, wire and cable, automotive interiors, and food. UV‑Vis, fluorescence, and color measurement models deliver absorbance, transmittance, and reflectance results with traceable calibration. Stable optics and standards‑aligned methods help teams get repeatable data across sites. Systems integrate with sample‑prep tools and environmental chambers to condition specimens for real‑world performance.

Types & Configurations

UV‑Vis Spectrophotometer

Quantify absorbance and transmittance from 190–1100 nm for pigments, stabilizers, and optical clarity in polymers and elastomers. Designs emphasize low stray light, narrow bandwidths, and robust sample handling.

Core Specs & Variants (UV‑Vis)

• Wavelength range: 190–1100 nm; bandwidth: 0.5–2 nm


• Detectors: photodiode array or PMT; stray light <0.05%


• Photometric accuracy: ±0.002 A; repeatability: ≤0.001 A (typical)


• Cuvette, film, and plaque holders; optional autosippers

Fluorescence Models

A fluorescence analyzer captures emission behavior of additives and whitening agents with high sensitivity and fast scans. Adjustable excitation/emission bandwidths and low noise support complex matrices.

Core Specs & Variants (Fluorescence)

• Excitation/emission ranges matched to material chemistry


• Bandwidth options for sensitivity vs speed


• High‑sensitivity detectors with low dark noise

Color Measurement Instruments

Manage color across resins, films, molded parts, inks, and packaging using CIE L*a*b*, ΔE, and reflectance data. Configurable d/8, 45/0, and sphere geometries with UV control cover opaque and translucent materials.

Core Specs & Variants (Color)

• Geometry: d/8, 45/0, diffuse sphere; gloss and UV control options


• Wavelength interval: ~10 nm; repeatability: ≤0.03 ΔE (typical)


• Methods aligned with ISO 11664 and ASTM D2244

Portable vs Benchtop

Handheld units enable shop‑floor checks and on‑site audits. Benchtop systems maximize stability, wavelength coverage, and automation. Shared data models help maintain traceability across locations.

Features & Advantages

Precision Optics & Build

Rigid frames and precision optics reduce drift and noise. Controlled thermal behavior supports consistent results in plastics and packaging workflows.

Standards & Software

Preloaded methods align with CIE colorimetry (ISO 11664), ASTM D2244, and common UV‑Vis practices; optional settings support USP <857> workflows. Software provides spectral curves, L*a*b*, ΔE, pass/fail rules, and customizable reports, with CSV/LIMS connectivity, versioned methods, and audit trails.

Sample Handling & Integration

Holders match pellets, plaques, films, inks, textiles, powders, and liquids. Integration with hot presses, ovens, and temperature‑humidity chambers standardizes conditioning before measurement.

Selection Guide

Wavelength Range & Resolution

Choose UV‑Vis ranges and bandwidths to match additives and clarity tests. Use appropriate interval spacing in color devices for reflectance accuracy.

Geometry & Modes

Select d/8 or 45/0 based on texture and gloss. Sphere systems handle structured or shiny parts. Use transmission for films and reflectance for opaque pieces. UV include/exclude manages fluorescent whitening agents.

Speed, Repeatability & Throughput

Balance scan speed with repeatability targets. Autosippers or carousels increase batch throughput without compromising accuracy.

Environment & Compliance

Maintain stable temperature and humidity for sensitive materials. Methods align with ISO 11664, ASTM D2244, and ASTM E308.

Applications

Plastics & Rubber

Control masterbatch and compound color with L*a*b* and ΔE. Verify UV stabilizers and optical clarity. Detect fluorescence from whitening agents.

Packaging & Printing

Ensure brand color for films, cartons, and labels. Evaluate inks and varnishes under multiple illuminants. Reduce press‑side matching time with handheld checks.

Coatings & Automotive Interiors

Assess gloss, texture effects, and color uniformity on coated panels and molded parts. Apply ΔE thresholds to standardize approvals across suppliers.

Food & Beverage

Monitor color in beverages, sauces, and powders using reflectance and absorbance data to support sensory alignment and shelf consistency.

Support, Manufacturing & Lifecycle

Backed by ISO 9001 certification and a National High‑Tech Enterprise team, our production includes in‑house CNC machining plus dedicated QA and calibration labs. OEM/ODM customization, a trained distributor network, remote support, spare parts, and software updates help protect testing capacity and extend instrument life. Routine calibration with certified references maintains traceability and audit‑ready records.

FAQ

What geometry should I use for textured plastics?

Use a sphere (d/8) system to average surface effects; 45/0 suits smooth, appearance‑critical parts.

How often should instruments be calibrated?

Follow your quality plan. Many labs perform daily checks and schedule full calibrations at defined intervals with traceable standards.

Can portable and benchtop units share data?

Yes. Use common methods, reference tiles, and synchronized software libraries to keep results comparable across sites.
