Wincom Company supplies a versatile selection of laboratory polarimeters engineered to measure the optical rotation, specific rotation, concentration, and sugar degrees of optically active substances. These instruments are vital for purity analysis and quantitative assays within the pharmaceutical, food and beverage, sugar refining, and chemical processing sectors in Bangladesh.

Their lineup ranges from traditional, low-maintenance manual equipment to advanced microcomputer-controlled automatic systems.

1. Manual Tier: Wincom WXG-4 Disc Polarimeter

A classic, non-electrical/mechanical solution preferred by educational labs or facilities requiring an ultra-budget, field-resilient tool that does not rely on extensive circuitry.

• Measurement Method: Visual balance via manual split-field observation using a built-in magnifying vernier scale 4X

• Measurement Range: -180 x to +180X (Full-Circle scale values).

• Vernier Reading/Resolution: 0.05X

• Light Source: Traditional Sodium Lamp (589.44 nm monochromatic optical path).

• Best For: Baseline compound differentiation (levorotatory vs. dextrorotatory) and teaching environments.

2. Industry Standard: Wincom WZZ-2B & WZZ-2S Automatic Series

The WZZ series represents Wincom’s high-demand, microcomputer-driven automatic benchtop units. They feature integrated photoelectric testing and servo-driven mechanics to completely eliminate human reading drift.

• Data Averaging: Features automatic repetition-measurement cycles that record up to 3 separate runs and display the precise mean value.

• Dark Sample Penetration: The WZZ-2S is equipped with an upgraded light tracking system capable of testing low-transmittance, dark-colored liquids down to just 1 sample transmittance.

• Output Connectivity: Outfitted with an RS232 serial interface port for seamless data transfers to a lab PC or a local micro-printer.

3. Advanced Multi-Mode: Wincom WZZ-3 / POL Series

Engineered for strict quality control laboratories (such as pharmaceutical manufacturing following pharmacopeia standards), this series adds multiple internal algorithmic processing scales.

• Data Recording: Performs automated repetition measurement up to 6 times, calculating the definitive average alongside the mean square root.

• Upgraded Interface: Transitions from basic character displays to a bright, 5-inch color LCD panel with a USB interface for flexible modern data tracking.
