Wincom Company supplies a competitive, budget-friendly lineup of Visible (Vis) and UV-Visible (UV-Vis) Spectrophotometers. These instruments are highly utilized in clinical laboratories, educational setups, water treatment facilities, and chemical analysis centers for quantitative colorimetric and photometric testing.

Their catalog bridges cost-effective manual visible-range options with higher-end digital scanning UV-Vis configurations.

1. Classic Visible (Vis) Spectrophotometers

These units isolate the specific visible spectrum range (typically 320nm to 1000nm or 335nm to 1000nm), optimized for daily routine chemical or biological assays where UV light transmission is not required.

Popular Model: Wincom 721 / 721(D)

The 721 series is an industry-standard, ultra-reliable economic model for straightforward absorbance and transmittance testing.

• Wavelength Range: 335nm to 1000nm

• Spectral Bandwidth: 5nm

• Wavelength Accuracy: pm 2nm

• Optical System: Single Beam, C-T Monochromator (1200 lines/mm grating)

• Stray Light: 0.5% T (at 360nm)

• Key Advantage: Exceptional sensitivity for a lower-tier budget instrument; highly favored by academic institutions and baseline quality control benches.

Alternative Manual/Digital Vis Focus: Wincom S23A / V22Y

• Slightly updated digital displays covering the standard 340nm to 950nm / 1000nm spectrums, built primarily for medical diagnostic colorimetry.

2. Advanced UV-Visible (UV-Vis) Combined Spectrophotometers

When a wider analytical window is required (such as DNA/RNA purity assessments or pharmaceutical compound tracking), Wincom provides dual-source instruments extending deep into the ultraviolet range.

High-Throughput Series: Wincom SP-UV52 (N/G) & UV752

• Wavelength Range: 200nm to 1000nm (covers full UV and visible boundaries)

• Spectral Bandwidth: 2nm (SP-UV52N) or 4nm (UV752 / SP-UV52G)

• Wavelength Accuracy: pm 2nm

• Stray Light: 0.1% T to 0.3% T (measured at 220nm and 340nm)

• Dual Light Source: Features both a Deuterium lamp for ultraviolet precision and a Tungsten-halogen lamp for the visible spectrum.

Premium Choice: Wincom SP-UV6D / UV6DS (Scanning Model)

• Wavelength Range: 190nm to 1100nm

• Optical Profile: Double Split-Beam optical layout.

• Interface: Large 8-inch integrated touch screen that processes internal spectrum scanning curves and standard curve data directly without requiring an external computer.
