7 Inch Square Magnetic Stirrer

• L7SM-S 7-inch large square magnetic stirrer is designed for mixing low-viscosity liquids and solid-liquid systems, widely adopted in chemical synthesis, physical & chemical analysis, biopharmaceutical and material science labs.
• Core parameters: 184×184mm (7 inch) monolithic glass ceramic square work plate, single stirring position; max working volume 10L per station, compatible with magnetic stir bars up to 80mm length; shaded pole motor, 1.5W motor output power, total unit power 30W.
• Speed range 0–1500rpm with scale knob speed adjustment; IP21 protection class; dual wide voltage 100–120V/200–240V, universal 50/60Hz.
• Dimension 215×360×112mm, net weight 3.8kg. Permissible ambient operating condition: 5–40℃, max 80%RH.
• Key advantages: 7-inch extra-large glass ceramic platform, superior chemical resistance, efficient heat conductivity, 10L large single-position stirring capacity, compatible with 80mm extra-long stir bars, wide 0–1500rpm scale speed regulation, heavy-duty stable chassis, universal mixing performance for multi-discipline routine experiments.

• L7SM-S 7-inch glass ceramic magnetic stirrer is medium-capacity general mixing equipment for chemical synthesis, biopharmaceutical, material R&D and physical & chemical testing labs, featuring extra-large corrosion-resistant glass ceramic platform, 10L stirring volume and stable durable performance.
• Monolithic glass ceramic plate delivers superior chemical tolerance over Nylon and standard stainless steel coated surfaces, resisting corrosion, discoloration and cracking during long-term organic synthesis and acid-base titration assays, with good thermal conductivity compatible with heated model upgrade.
• 10L stirring volume paired with 80mm extended stir bars bridges 5L lab small-scale and 20L pilot-scale equipment, ideal for process scale-up exploration and simultaneous blending of bulk parallel samples.
• Simple shaded pole motor structure with low failure rate; heavy weighted 3.8kg chassis ensures stable center of gravity without sliding or tipping under full large-volume load to guarantee safe long-duration continuous experiments.
• Stepless 0–1500rpm scale knob speed adjustment with intuitive operation and no complicated setup, easy for student operators and frontline testing staff to master quickly.
• Dual wide voltage design allows one unit compatible with 110V European & American markets and 220V Asian markets, reducing inventory pressure without separate stock versions for export.
• Spacious regular chassis enables neat side-by-side multi-unit arrangement to maximize lab bench utilization and boost overall sample throughput.
• Integrated rigid body with minimal wear parts offers outstanding comprehensive cost performance for bulk procurement in university teaching labs, third-party testing institutions and enterprise R&D facilities.

• Routine chemical, biological and pharmaceutical labs require large corrosion-resistant platform for medium-volume low-viscosity & solid-liquid samples within 10L per batch:
  Choose L7SM-S with 7-inch monolithic glass ceramic anti-corrosion plate, 10L stirring capacity and 80mm long stir bars to eliminate sediment dead zones.
• Frequent use of strong acid, alkali and various organic solvents causes easy damage to standard Nylon/aluminum coated plates:
  Integral glass ceramic surface withstands all common corrosive reagents with wear & aging resistance to extend equipment replacement cycle drastically.
• Lab scale-up experiments between 5L small-scale and 20L pilot scale demand stable medium-large volume stirring equipment:
  Rated 10L mixing capacity matched with heavy 3.8kg weighted base delivers vibration-free stable running under full load for scale-up exploration assays.
• Bulk export to multi-country overseas clients covering both 110V and 220V mains zones without separate model inventory:
  Dual universal voltage 100–120V/200–240V supports all global markets with one single model to simplify stock management.
• Sufficient lab bench space with demand for side-by-side multi-stirrer layout to raise daily sample throughput:
  Regular wide chassis allows neat parallel arrangement; 7-inch large platform offers better compatibility with all beaker and Erlenmeyer flask sizes.
• Bulk procurement for university teaching and third-party testing labs prioritizing simple low-failure structure with minimal post-purchase maintenance:
  Shaded pole motor features simple durable construction without fragile precision spare parts, extremely low repair and consumable cost over long service life.

• Standard factory package includes L7SM-S magnetic stirrer main unit, power cord and printed English operation manual. Medium-volume 10L solid-liquid & low-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 & biopharmaceutical 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.
