Description
The Across International HP11 Digital Heated Magnetic Stirrer is a large-capacity laboratory hot plate stirrer designed for precise heating and efficient magnetic mixing. Using a rotating magnetic field beneath the heating surface, the unit spins a PTFE-coated stir bar inside glass vessels to create uniform agitation without mechanical contact.
Magnetic stirrers are widely used in chemistry, biology, pharmaceutical research, and laboratory testing because they provide quiet operation, minimal maintenance, and reduced contamination risk compared to mechanical stirring systems.
The HP11 model features PID digital temperature control, adjustable stirring speeds up to 2000 RPM, and a large 11-inch ceramic-coated aluminum heating plate capable of reaching temperatures up to 350°C. With a maximum stirring capacity of 2 gallons, the HP11 is ideal for larger laboratory reactions, solution preparation, and heating applications.

Advantages of Magnetic Stirring
Magnetic stirrers are commonly used in laboratories because they offer:
-
Quiet operation
-
Minimal maintenance
-
No exposed mechanical components
-
Easy sterilization and cleaning
-
Reduced contamination risk
Because glass does not interfere with magnetic fields, stir bars operate efficiently in beakers, laboratory flasks, and reaction vessels.
Magnetic stirrers are ideal for:
-
Chemical reactions
-
Laboratory solution mixing
-
Biological experiments
-
Pharmaceutical preparation
-
Sample preparation and heating
For highly viscous liquids or very large volumes, mechanical stirring systems may be required.
