The Wincom WT-HM6 (often cataloged as HM-A6 or HM-A6H with holder) is a professional multi-position six-joint laboratory heating mantle manufactured by Wincom Company Ltd.. It is specifically engineered to heat up to six round-bottom flasks simultaneously, making it an ideal choice for high-volume distillation, extraction, or reflux procedures.
Technical Specifications
- Capacity Options: Available configurations support either 6 × 250 ml or 6 × 500 ml flasks.
- Power Output: Ranges from 1080W to 1500W depending on the specific flask capacity option selected.
- Heating Layout: Built as a six-joint multi-row setup with independent or linked structural controls.
- Material Composition: Utilizes high-temperature resistant internal fiberglass cloth insulation to safely cradle glass vessels without liquid residue or hot spots.
Core Benefits
- Multi-Flask Efficiency: Replaces the need for six separate heating elements, maximizing lab bench space and optimizing energy consumption.
- Enhanced Safety: The enclosed fabric system forms an insulated barrier around the vessel, making it far safer than standard hot plates when working with flammable solvents.
- Uniform Conduction: Contours directly to round-bottom flasks to ensure an even distribution of thermal energy and minimize boiling delays.
Variants & Ordering Notes
Depending on your precision requirements, Wincom supplies this equipment series in distinct formats:
