Laboratory overhead (electric) stirrers for mixing low-, medium- and high-viscosity liquids, and liquid/solid mixtures, in chemical synthesis, biopharmaceuticals, food and beverage, and other fields. Three series: general-purpose LES, research-grade DNP and professional BKD, with knob-controlled or digital timer models.
Features
- LES general-purpose series: permanent-magnet DC motor with constant-power compensation; durable and reliable
- DNP research series: high speed-control accuracy with 5 speed-memory presets; motor and overload protection
- BKD professional series: brushless DC motor for high-viscosity, high-load and long continuous operation; fault display with automatic stop; remote control capable
- Suitable for liquid/liquid and solid/liquid mixing experiments that require strict speed control
Specifications
- Power supply: 220 V, 10 A grounded outlet
- Applications: chemical synthesis, biopharmaceuticals, food and beverage, pharmaceutical, chemical and biotechnology laboratories

Precautions
- Electrical safety: use a dedicated grounded 220 V/10 A outlet; never plug or unplug with wet hands; do not damage or modify the power cord.
- Hazardous media: only for media that do not react dangerously during processing. Handle toxic or volatile media in closed containers inside a fume hood.
- Monitoring: if the impeller runs off-center, stirs unevenly or the medium splashes, stop immediately and adjust. If the instrument moves, stop and stabilize it.
- Installation: center the impeller in the vessel without touching the wall or bottom; tighten the impeller from bottom to top to prevent slipping; do not disassemble or adjust parts; use only original spare parts.
- Faults: disconnect power immediately and contact after-sales service; do not repair yourself.
- Cleaning: clean the impeller promptly after use to prevent residue; unplug when not in use for a long time and store in a cool, dry place.
