• Two independent LED digital tubes display real-time stirring speed and plate temperature separately for intuitive parameter reading.
• High-temperature warning mechanism: after power cut-off, the LED flashes "HOT" continuously if plate temperature exceeds 50℃ to prevent operator scald injury.
• Auto power-off overheat protection at 320℃, paired with IP42 dust & splash resistant housing to resist minor liquid spills and dust ingress, extending service life and operation safety.
• Universal dual wide voltage design compatible with 110V European/American and 220V Asian markets, no separate voltage stock versions required for export inventory.

• Product positioning: Compact single-position high-temperature magnetic hotplate stirrer for daily constant-temperature processing of micro samples in biological and physical-chemical labs, suitable for small-volume synthesis, wet digestion, solvent reflux and sample extraction routine workflows.
• 5-inch stainless steel ceramic composite platform balances mechanical strength, heat transfer efficiency and chemical resistance; no deformation or peeling under long-term heating up to 280℃, compatible with all acid, alkali and organic reagent systems.
• External high-precision PT1000 temperature probe collects real actual liquid temperature inside samples to correct temperature deviation between plate and solution, meeting strict temperature accuracy requirements of pharmacopoeia and testing standards.
• 3W brushless DC drive motor runs quietly without electric sparks for safe experiments with organic solvents and low-boiling flammable reagents; zero carbon brush wear parts eliminate regular consumable replacement to cut lab maintenance cost.
• Multi-layer safety protection system: auto power cut at 320℃ overheat threshold, flashing HOT warning after power off at 50℃, IP42 dust & splash resistant housing to protect internal motor and heating modules from minor liquid spills and dust accumulation.
• Slim lightweight chassis with net weight only 1.8Kg fits narrow fume hood work zones and compact bench tops, replacing bulky old-fashioned stirrers to save lab space.
• Dual universal voltage specification covers both 110V European/American and 220V Asian markets; distributors manage one single model for all mainstream overseas regions to simplify inventory control.
• Excellent cost performance for bulk orders, ideal for university teaching labs, small third-party testing institutes and enterprise R&D micro screening experiments.

• Daily processing of single micro sample batches under 3L, compact equipment required for narrow fume hood workstations:

  Choose slim single-position L280SM-H-Pro, net weight only 1.8Kg with compact dimension; 5-inch anti-corrosion ceramic plate meets standard small-volume stirring & heating demands.

• Experiments require high-temperature workflows up to 280℃ beyond standard stirrer limits, with demand for accurate real liquid temperature measurement:

  Stable constant heating up to 280℃ matched with external PT1000 probe to eliminate plate-solution temperature gap, ideal for strong-acid digestion and high-temperature organic synthesis.

• Frequent use of organic solvents and low-boiling flammable reagents with safety concerns over electric spark generation:

  Spark-free brushless DC motor design eliminates carbon brush discharge for full safe operation with all flammable reaction systems.

• Minor liquid spills and dust accumulation occur during experiments, dust & splash resistant housing required for extended equipment service life:

  IP42 protection grade housing blocks dust and trace reagent splashes; paired with dual safety systems (320℃ overheat cut-off + post-run HOT warning) for full protection.

• Bulk export to multi-region overseas markets covering both 110V and 220V grids without separate model inventory:

  Dual universal wide voltage 100–120V/200–240V supports all global power grids with one unit to reduce stock SKU pressure.

• Bulk procurement for university teaching, small third-party testing and enterprise micro-screening R&D prioritizing low maintenance, high precision and cost-effective compact hotplate stirrer:

  Maintenance-free brushless motor requires zero regular consumable replacement; easy-to-clean anti-corrosion ceramic plate and precise PID temperature control suit standardized bulk micro-sample processing.
