Wincom Company supplies a reliable, budget-friendly selection of Melting Point Apparatuses engineered to replace traditional, uneven oil-bath setups with precise micro-processor heating blocks. These instruments are highly utilized by pharmaceutical laboratories, chemical manufacturing plants, and university research benches across Bangladesh to assess compound purity and identify crystalline organic substances.

Their product catalog is split into two primary operational categories: Semi-Automated Visual models and Fully Automatic Photoelectric models.

Semi-Automated Visual Series (Wincom WRS-1B / WRS-2A)

This series features digital temperature management and electronic displays but relies on a lab technician to visually track the melting process through an illuminated magnifying lens.

• Operation: The user dials in a starting temperature and a slow heating rate. They then observe the sample and manually press a button to lock in the initial and final melting points.

• Temperature Range: Ambient to 300°C

• Capillary Capacity: Processes 1 sample (WRS-1B) or 3 samples simultaneously (WRS-2A).

• Heating Rate: Linear adjustable from 0.2°C/min up to 5.0°C/min.

• Best For: Educational institutions and standard quality control benches requiring robust, low-maintenance hardware.

Fully Automatic Photoelectric Series (Wincom WRS-2 / WRS-3)

Engineered for high-throughput analytical testing, this premium tier eliminates human observation error completely by using photoelectric sensors to automatically log the entire melting curve.

• Operation: As the crystalline powder inside the capillary tube transforms into a clear liquid, light transmission shifts. Photoelectric sensors detect this change in real-time, instantly saving the starting and ending points.

• Temperature Range: Ambient to 360°C (highly suited for high-temperature polymers and specialized pharmaceuticals).

• Capillary Capacity: Measures 3 samples simultaneously and calculates an instant mean average.

• Data Connectivity: Features onboard LCD touchscreen menus, built-in memory storage, and RS232/USB interfaces to push data directly to an external lab printer or computer tracking suite.
