Laboratory magnetic stirrer

• LSM-PB magnetic stirrer is designed for low-viscosity liquid and solid-liquid mixing experiments, widely adopted in chemistry, biology, material science and other laboratory fields.
• Core parameters: Φ135mm (5 inch) round Nylon+GF work plate, single stirring position; max working volume 3L per position, compatible with magnetic stir bars up to 50mm length; maintenance-free brushless DC motor, 3W motor output power, total unit power 10W.
• Speed range 0–1500rpm with scale knob speed indication; IP42 protection class; universal wide voltage 100–240V, 50/60Hz.
• Dimension 150×260×80mm, net weight 1.8kg. Permissible ambient operating condition: 5–40℃, max 80%RH.
• Key advantages: Wide 0–1500rpm adjustable speed, 3L large single-position stirring volume, Nylon+GF housing with excellent weak acid & alkali resistance, IP42 upgraded dust & splash-proof rating, maintenance-free brushless motor, multi-scenario compatibility for chemical synthesis, biological research and physical analysis.

• Stepless scale speed regulation from 0 to 1500rpm covers gentle low-speed blending, medium-speed dispersion and high-speed suspension dissolution, enabling precise mixing force control for diverse experimental systems.
• Max 3L large stirring capacity per station fits big Erlenmeyer flasks, beakers and reaction vessels, meeting demands of chemical synthesis and bulk biological sample pre-processing.
• Integrated Nylon+GF housing and top plate deliver outstanding resistance to weak acid and alkali; minor reagent splashes will not corrode the unit for long-term stable service life.
• Upgraded IP42 protection class provides stronger dust and splash resistance than standard IP21, protecting internal circuits from minor liquid spills and bench dust in open lab environments.
• Maintenance-free brushless DC motor eliminates carbon brush abrasion, runs quietly and stably, no regular consumable replacement required for long continuous batch mixing to cut lab maintenance expenditure.
• 5-inch large round stirring surface prevents tipping of large-volume vessels, compatible with standard magnetic stir bars up to 50mm length for most medium & large-volume mixing systems.
• Auto-adaptive universal 100–240V wide voltage works plug-and-play worldwide without extra power adapters for cross-border export.
• Balanced weighted chassis realizes vibration-free stirring to avoid splashing and waste of large-volume samples; 1.8kg moderate weight for easy relocation and placement.

• LSM-PB large-volume single-position magnetic stirrer targets mixing of low/medium viscosity liquid and solid-liquid systems, applicable for chemical synthesis, biological culture, material dispersion, physical analysis and other general lab workflows, balancing large capacity and upgraded protection rating.
• 5-inch Nylon+GF round plate resists weak acid and alkali corrosion; minor daily acid/alkali spills can be wiped clean with damp cloth without aging or cracking, delivering better durability than standard PET material.
• IP42 dust & splash-proof rating blocks minor liquid splashes and ambient dust from damaging internal motor circuits, lowering risks of short circuit and breakdown for long-term open-bench lab operation.
• 3L max stirring volume outperforms compact economical mini stirrers, capable of handling large-volume reaction systems for university synthesis labs and small-scale chemical R&D testing rooms.
• 3W output brushless DC drive motor delivers sufficient magnetic force; full 0–1500rpm speed range covers low-speed static blending to high-speed powder suspension with quiet vibration-free running.
• Solid weighted 1.8kg chassis avoids sliding or tipping when stirring large-volume samples; elongated body layout allows side-by-side arrangement of multiple units to boost lab overall sample throughput.
• Universal 100–240V wide voltage complies with power standards of Europe, America, Southeast Asia and other overseas regions, no regional voltage separation required for bulk export shipments.
• Simple low-maintenance structure with no fragile carbon brush consumables, moderate procurement cost for bulk purchase in teaching and R&D labs, superior comprehensive durability compared to entry-level mini stirrers.

• Chemical synthesis and material R&D labs require 3L large-volume mixing with frequent weak acid & alkali reagent use:
  Choose LSM-PB with 3L single-position capacity, Nylon+GF plate resisting mild acid/alkali corrosion, IP42 splash-proof rating fits frequent liquid handling in synthesis assays.
• Lab benches with frequent reagent splashes and dust demand upgraded dust & liquid splash protection for equipment:
  Upgraded IP42 protection outperforms standard IP21 to effectively block splashed liquid and dust, extending motor service life and cutting breakdown maintenance frequency.
• Processing medium/large-volume flasks & beakers requires wide round platform compatible with 50mm long stir bars:
  5-inch large-diameter plate supports stir bars up to 50mm length, 3L max volume meets bulk blending demands for large sample batches.
• Long-term uninterrupted batch stirring workflows with low maintenance requirement and no frequent carbon brush replacement:
  Maintenance-free brushless DC motor with zero carbon abrasion enables multi-day continuous operation without regular consumable change.
• Bulk procurement for multi-country overseas clients requires compatibility with global varying mains voltage standards:
  Full-range auto-adaptive 100–240V wide voltage with 50/60Hz universal frequency, no separate voltage adapters needed for worldwide export.
• Routine biological & physical analytical sample pre-processing needs flexible full-range speed control from 0 to 1500rpm:
  Wide stepless scale speed adjustment; low speed for gentle blending of cell culture medium, high speed for fast solute dissolution and powder dispersion.

• Standard factory package includes LSM-PB magnetic stirrer main unit, power cord and printed English operation manual. Large-volume solid-liquid and low-viscosity liquid 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 & biological 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.
