LCD 4-Channel Digital Magnetic Hotplate Stirrer

• Fully independent 4-channel control system: each position supports separate start/stop and independent speed/temperature setting without mutual interference, enabling simultaneous parallel experiments with 4 distinct process parameters for high-throughput batch sample processing.
• Closed-loop PID digital temperature control delivers stable constant heating up to 340℃ per station with minimal thermal fluctuation, suitable for parallel workflows including organic synthesis, environmental water digestion, pharmaceutical extraction and microbial constant-temperature incubation.
• Independent 1.8W explosion-proof brushless DC motor for every position runs quietly, vibration-free and spark-free with zero maintenance; adjustable speed range 200–1500rpm with ±20rpm control accuracy to match fluids of varying viscosity.
• Four Φ135mm stainless steel ceramic coated heating plates provide excellent resistance to strong acid, alkali and organic solvents, uniform fast heat transfer, no peeling, deformation or discoloration under long-term 340℃ heating, easy to wipe clean after reagent spills.
• PT1000 high-precision temperature probe can be connected to each channel to immerse directly into reaction liquid, eliminating plate-solution temperature offset and capturing real internal sample temperature to meet traceable precision standards for third-party testing and academic research.
• Integrated multi-layer global safety circuit automatically cuts all heating output at 420℃ overheat threshold to prevent dry heating and vessel rupture; IP21 dust-proof housing blocks dust ingress into internal circuits and motor modules to extend service life.
• Separate independent LCD digital display on each station shows real-time stirring speed and plate temperature of the corresponding channel, clear parameter monitoring for all parallel sample groups.
• Wide selection of optional supporting accessories including support stands, clamps, temperature probes and reflux assemblies allows independent setup of constant-temperature reflux & distillation equipment for any single position, flexibly adapting to diverse parallel experimental schemes.

• Product positioning: 4-channel high-throughput parallel high-temperature magnetic stirrer for synchronous batch sample processing in chemical, pharmaceutical, environmental and biological labs. It completes 4 sets of control experiments in one run to drastically shorten cycles of batch digestion, extraction and synthesis, replacing four single-position stirrers to cut procurement cost and save bench footprint.
• Fully separated hardware for four channels: independent motor, heating module and display panel operate without cross-interference. Users can set distinct temperature & speed parameters for each group, ideal for academic gradient temperature / gradient stirring rate comparison assays.
• Each station supports 10L large-volume stirring with standard 40mm stir bars, stably accommodating 50–1000mL beakers and flat-bottom flasks. Wide heating range up to 340℃ meets demanding parallel workflows including mineral digestion, high-boiling solvent reflux and pharmaceutical extraction.
• Intelligent closed-loop PID temperature control delivers stable heating with minimal high-temperature drift; paired with external PT1000 probe to capture accurate real liquid temperature, delivering highly repeatable parallel sample data compliant with pharmacopoeia and third-party testing standards.
• Brushless DC motor eliminates carbon brush wear for lifetime maintenance-free operation; zero electric spark output enables safe parallel reflux experiments with low-boiling flammable solvents such as ethanol and acetone, removing fire risks during multi-station simultaneous running.
• Integrated multi-layer safety suite: global 420℃ overheat cut-off protection, IP21 dust-proof housing and fire-resistant insulated chassis ensure stable long-duration continuous multi-position operation, qualified for unattended batch digestion workflows.
• Universal dual wide voltage works directly for 100–120V EU/US and 200–240V Asian power grids, distributors manage one unified model for multi-region clients to simplify stock SKU control.
• Optional stands, temperature probes and reflux assemblies can be equipped separately for each station, supporting flexible mixed layouts: full batch digestion on all positions or partial reflux setups to adapt to variable high-throughput experimental plans.

• Standard factory package includes L340SM-H-4S 4-channel independent high-temperature magnetic hotplate stirrer main unit, power cord, 4 pcs external PT1000 temperature sensors and printed English operation manual. 4-group parallel high-temperature stirring experiments can be carried out immediately after unboxing without extra basic accessories.
• OEM private branding customization service is available for bulk orders to create exclusive brand visuals for lab instrument independent online stores and overseas environmental, pharmaceutical & chemical research exhibition marketing channels.
• Thick shockproof separate carton fully lined with high-density foam buffer; four ceramic plates are individually isolated for protection against long-distance sea & air freight vibration and compression, preventing plate scratches and impact damage to internal multi-channel motor & heating components.
• In-stock orders ship within 3–10 working days. Goods will be packed and dispatched uniformly after model & accessory confirmation to shorten lead time for overseas monitoring stations, pharmaceutical plants, research institutes and instrument distributors.
• Multiple cross-border logistics options including sea freight, air freight and international courier are offered to match cost-effective transport solutions based on order volume and requested arrival time.
