20 ML Plus Magnetic Stirrer – High-Capacity Digital Mixing System
The 20 ML Plus Magnetic Stirrer is a robust, precision-engineered laboratory instrument meticulously developed to solve processing limitations when working with heavy liquid solutions. Built around cutting-edge digital control paradigms, this high-performance blending platform effectively agitates large volumes of liquids up to a maximum fluid capacity of 20 Liters (H₂O). It effortlessly closes the gap between bench-scale experimentation and industrial process staging.
With an adaptable speed profile spanning from **150 to 1500 RPM**, the 20 ML Plus provides smooth, variable mixing. This capability covers everything from gentle biochemical cell culture agitations to the high-shear blending of complex, high-viscosity reagents. The core driver consists of an efficiency-optimized, maintenance-free **Brushless DC (BLDC) motor**. This motor provides consistent torque transformation while automatically matching power demands when working against high solution resistances or transient fluid viscosity changes.
Constructed to excel under aggressive laboratory conditions, the instrument features a generous 300 x 350 mm premium grade stainless steel top plate. This oversized layout offers superior footprint security for heavy, large-scale glass beakers and reaction vessels, while providing broad resistance against toxic chemical corrosives. Integrated microprocessors drive all processing systems, displaying actual versus targeted rotational metrics in real-time via a backlit alphanumeric LCD layout. It also utilizes a last-run parameter memory loop to optimize repetitive operational testing blocks.

User-Centric Features & Target Pain-Point Corrections
The Pain: Fragmented operations caused by small-volume limits.
The Benefit: Seamlessly mixes up to 20-liter fluid loads inside one container. This makes it ideal for staging pilot-scale reactions, preparing bulk cell culture media, and running large-scale diagnostic buffer lots.
The Pain: Mixing speed drops and stalls when solution viscosities change.
The Benefit: An integrated Brushless DC (BLDC) motor actively tracks fluid friction, maintaining a constant target speed even as solutions thicken, while entirely eliminating routine belt-drive upkeep costs.
The Pain: Speed drift and manual dials make replicating exact runs difficult.
The Benefit: Digital microprocessor tracking combined with a high-contrast backlit LCD display guarantees precise, repeatable runs. Operators can constantly verify real-time versus target RPM parameters at a glance.
The Pain: Large vessels slipping or causing chemical degradation on weak platforms.
The Benefit: A heavy-duty 300x350 mm stainless steel work surface effortlessly carries large, oversized beakers. This durable layout offers maximum chemical protection and stands up to harsh, everyday splash scenarios.
