Wincom Company manufactures high-precision Dual Split-Beam (sometimes designated as Split-Beam) UV-Vis Spectrophotometers engineered for rigorous quantitative analysis, multi-wavelength scanning, and kinetic testing.

By splitting the initial light beam into two paths within the monochromator, these instruments constantly monitor and correct for light source fluctuations. This delivers significantly higher stability, lower baseline drift, and superior repeatability compared to standard single-beam entry models—making them a preferred choice for pharmaceutical QA/QC, advanced chemical research, and environmental testing labs in Bangladesh.

Top Dual Split-Beam Choice: Wincom SP-UV6D / SP-UV6DS

The SP-UV6 series represents Wincom’s premium platform utilizing this advanced optical configuration. It eliminates the need for manual reference cell blanking during long scanning procedures.

Core Technical Specifications

• Optical System: Split-Beam (Dual Path) monitoring layout with a high-performance 1200 lines/mm holographic grating.

• Wavelength Range: 190 nm to 1100 nm (Full Ultraviolet and Visible spectrums).

• Spectral Bandwidth: Fixed 2 nm for excellent resolution of complex molecular peaks.

• Wavelength Accuracy: pm 0.3 nm (highly precise calibration tracking).

• Wavelength Repeatability:  0.1 nm.

• Stray Light: 0.05 T (measured at 220 nm via NaI and 360 nm via NaNO, ensuring accurate absorbance readings even at high chemical concentrations.

• Photometric Range: 0 to 200T -0.3 to 3.0 A.

Key Operational Capabilities

• Standalone Touch Interface: Features an integrated 8-inch color touch screen. It processes, displays, and saves complex scanning curves, multi-wavelength calculations, and standard curves directly on the device without requiring an external PC.

• Dual Light Source Stability: Automatically switches between a high-output Deuterium lamp (for UV) and a Tungsten-Halogen lamp (for Vis), with lifetime tracking metrics built into the firmware.

• Data Portability & Expandability: Equipped with USB and RS232 interfaces. When paired with Wincom’s optional PC scanning software, it unlocks comprehensive kinetics, DNA/Protein analysis, and full-spectrum data archiving.

• Robust Cell Capacity: Standard configuration includes a motorized or manual 4-position 10mm cell holder, easily upgradeable to long-pathlength holders (up to 100mm) for low-concentration water analysis.
