Corrosion-resistant ceramic magnetic stirrer

• LSM-S high-power large-volume magnetic stirrer is widely used in chemical labs, pharmaceutical industry and biotechnology fields. It delivers powerful stirring performance with corrosion-resistant plate, suitable for all kinds of chemical reactions and mixtures, especially efficient mixing experiments of viscous liquids.
• Core parameters: Φ135mm (5 inch) round work plate with stainless steel base & ceramic coating, single stirring position; max working volume 20L per station, compatible with magnetic stir bars up to 80mm length; maintenance-free brushless DC motor, 10W motor output power, total unit power 30W.
• Speed range 0–1500rpm with scale knob speed adjustment; IP21 protection class; universal wide voltage 100–240V, 50/60Hz.
• Dimension 160×280×85mm, net weight 2.8kg. Permissible ambient operating condition: 5–40℃, max 80%RH.
• Key advantages: Compact footprint to save bench space, stainless steel ceramic composite plate with superior chemical resistance, 20L ultra-large stirring volume, compatible with 80mm extra-long stir bars, precise 0–1500rpm wide speed control, long-lasting maintenance-free brushless motor, excellent performance for high-viscosity material mixing, stable & durable structure.

• Compact streamlined chassis occupies minimal bench space, fits limited-space labs and fume hoods, balancing large-volume stirring capacity and space utilization.
• Composite work plate with stainless steel substrate & ceramic top layer; ceramic surface resists all kinds of acid, alkali and organic solvents, scratch & wear resistant, easy to clean after reagent splashes for extended service life.
• Max 20L ultra-large single-position stirring volume outperforms standard small & medium stirrers, compatible with large-volume beakers and small reaction kettles to meet pilot test and bulk material blending demands.
• Supports extra-long magnetic stir bars up to 80mm length; long stir bars fully agitate large & high-viscosity systems to eliminate local sediment and improve mixing uniformity.
• Full-range stepless scale speed regulation from 0 to 1500rpm: low speed for gentle blending of biological culture medium, medium speed for routine reagent dispersion, high speed for powerful suspension of viscous & easily precipitated materials, matching diverse experimental workflows.
• High-power maintenance-free brushless DC motor delivers stable 10W strong output without performance decay during long continuous mixing; carbon-brush-free design removes regular consumable replacement work to cut lab maintenance expenditure.
• IP21 dust-proof chassis prevents internal circuit damage caused by accumulated ambient dust, suitable for daily operation in open conventional laboratories.
• Solid weighted 2.8kg unit avoids sliding and violent vibration when stirring 20L large-volume liquid, realizing stable running and preventing sample splashing loss.

• LSM-S high-power 20L magnetic stirrer targets pilot and large-volume sample processing workflows for chemical synthesis, pharmaceutical process development, biological fermentation and material R&D labs, featuring ultra-large capacity, heavy corrosion-resistant plate and powerful mixing performance for viscous fluids.
• Ceramic coated stainless steel plate combines structural rigidity and outstanding chemical tolerance, resisting erosion and damage from strong acid, alkali and all organic solvents for long-term service, ideal surface material for chemical synthesis and organic reaction assays.
• Max 20L stirring volume paired with 80mm extra-long stir bars handles lab scale-up and pre-pilot reaction systems, solving the limitation of standard 3L/5L stirrers unable to process large batches of materials.
• 10W high-power brushless motor with abundant power reserve delivers stable rotation without stall or speed drop when mixing high-viscosity slurries and suspensions; supports 7×24 hour non-stop operation for mass testing in factory R&D labs.
• Stepless 0–1500rpm scale speed adjustment with intuitive operation, allowing technicians to quickly select matching speed range based on material viscosity and volume with low operation threshold.
• Heavy weighted 2.8kg base ensures stable center of gravity, eliminating sliding and tipping risks even when fully loaded with 20L liquid to guarantee safe long-duration experiments.
• Auto-adaptive universal 100–240V wide voltage complies with global lab power standards, plug-and-play for worldwide bulk export shipments without regional voltage separation.
• Integrated simple chassis with few fragile spare parts offers controllable procurement cost for bulk purchase in R&D and teaching labs, delivering outstanding comprehensive cost performance over long service life.

• Chemical, pharmaceutical and biological pilot labs need to process dozens of liters of reaction materials per batch with frequent use of strong acid, alkali and corrosive organic reagents:
  Choose LSM-S with 20L ultra-large stirring capacity, stainless steel ceramic composite plate resisting all chemical corrosion, 80mm long stir bars for high-viscosity large-volume systems.
• Experimental materials are high-viscosity and prone to sedimentation, while standard low-power stirrers deliver weak mixing power and obvious stratification:
  10W high-power brushless motor provides sufficient torque, paired with extended 80mm stir bars to fully agitate thick slurries for uniform mixing without local sediment.
• Requirement for 7×24 hour long-term non-stop continuous stirring with minimal equipment maintenance and consumable replacement:
  Maintenance-free brushless DC motor with zero carbon abrasion enables multi-day continuous operation, eliminating regular carbon brush purchase and replacement to cut post-purchase repair workload drastically.
• Limited lab bench space but demand for large-volume stirring equipment for scale-up tests:
  Compact chassis design occupies smaller footprint than competitors with equal capacity, fits standard fume hoods and lab workstations easily.
• Bulk procurement for multi-country overseas clients requires compatibility with varying national mains voltage standards:
  Full-range auto-adaptive 100–240V AC voltage with universal 50/60Hz frequency, no separate voltage adapters required for worldwide export.
• Routine organic synthesis and pharmaceutical R&D reactions need flexible full-range speed control from 0 to 1500rpm for multi-stage processes:
  Wide stepless scale speed adjustment; low speed for fermentation culture medium, high speed for fast dispersion & suspension of powder and viscous solutes.

• Standard factory package includes LSM-S large-volume magnetic stirrer main unit, power cord and printed English operation manual. 20L large-volume & high-viscosity material mixing experiments can be carried out right after unboxing and power-on without extra basic accessories.
• OEM private branding customization service is available for bulk orders to create exclusive brand visuals for online lab instrument stores and overseas chemical & pharmaceutical research exhibition promotion.
• Thick shockproof separate carton filled with high-density foam buffer withstands long-distance jolt and extrusion during sea & air freight, greatly reducing risks of shell dent and internal motor component damage in cross-border shipment.
• In-stock orders ship within 3–10 working days. Goods will be packed and dispatched uniformly after parameter confirmation to shorten lead time for overseas R&D & teaching labs 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.
