SH-3 Hot Plate Magnetic Stirrer 5000ml Capacity - Dual Control

Our review of the SH-3 Hot Plate Magnetic Stirrer finds it best suited for labs and technicians who need a compact, higher-capacity unit for routine mixing and heating. The single biggest reason to consider this unit is its increased stirring power and volume capacity compared with smaller desktop stirrers, allowing reliable agitation of up to 5000ml while also providing independent heating control. The combination of stepless speed control and a 380C maximum plate temperature makes the SH-3 a practical workhorse for chemistry bench work, electroplating setups, prototype labs and home brew experiments where moderate heat and strong stirring are required.

Key Features

• Increased stirring power: The motor power is doubled from the prior model to provide stronger torque for larger volumes up to 5000ml.
• Wide speed range: Stepless adjustment from 100 to 2000 rpm lets the user dial in gentle circulation or vigorous mixing without stepped jumps.
• Independent dual control: Separate knobs for heating and stirring allow simultaneous use while adjusting each function without affecting the other.
• High maximum temperature: A plate temperature rated to 380C supports applications that require elevated heat, such as concentrated solvent work or drying steps.
• Complete accessory pack: The unit ships with a clamp, standing rods, fuse, power line, US plug and a Teflon-coated stirring bar so it is ready to use on arrival.
• Certified safety: CE safety certification offers an added level of assurance for workshop and lab environments.

Who It's For

The SH-3 is aimed at small laboratories, schools, hobbyists and light industrial users who need a single compact unit capable of handling larger batches than typical benchtop stirrers. It is especially useful where both heat and magnetic stirring are required at the same time, for example electroplating, reagent warming, small-scale synthesis and home brew wort circulation.

Users who require precision temperature stability to within tenths of a degree or specialist digital programmability should look elsewhere, as this unit focuses on robust mechanical stirring and practical heating rather than high-precision temperature control features.

Pros & Cons

Pros

• Strong stirring capability for up to 5000ml, making it suitable for larger lab batches.
• Stepless 100-2000 rpm control gives flexible mixing speed without discrete steps.
• Dual, independent controls let operators heat and stir simultaneously with simple adjustments.
• Includes accessories and a Teflon-coated stir bar so it is ready to operate out of the box.

Cons

• Temperature control can fluctuate by a few degrees during use, so it is less suited to tasks needing very tight thermal stability.
