A magnetic stirrer rotates a stir bar through a changing magnetic field to mix liquids without a driven shaft entering the vessel. Typical uses include buffer and reagent preparation, dissolution, and routine solution mixing.
A changing magnetic field rotates a stir bar inside the vessel without a shaft passing through the closure. Coupling is affected by liquid viscosity, vessel base, stir-bar dimensions and speed.
Where Magnetic Stirrer fits
Suitable processes
Magnetic Stirrer is commonly shortlisted for Buffer and reagent preparation, Dissolution, and Routine solution mixing. These uses orient the Magnetic Stirrer enquiry; suitability still depends on the exact model, method and site conditions.
Specify the load and temperature profile
For Magnetic Stirrer, the enquiry should document Liquid volume, viscosity and vessel geometry and Required speed range and stability at low or high load. Acceptance values for the proposed Magnetic Stirrer should come from the buyer's method, URS or tender rather than catalogue assumptions.
Confirm performance, utilities and accessories
Ask for the exact Magnetic Stirrer model, usable chamber or vessel capacity, operating range, stated uniformity or stability basis, controller and sensor type, utilities, accessories and any validation documentation required for the application.
Typical applications for Magnetic Stirrer
Buffer and reagent preparation.
Dissolution.
Routine solution mixing.
Small-scale chemical preparation.
Selecting the right Magnetic Stirrer
Application or load: Liquid volume, viscosity and vessel geometry.
Required performance: Required speed range and stability at low or high load.
Configuration and compatibility: Stir-bar dimensions, magnetic coupling and plate size.
Site, utilities and support: Need for heating, external temperature sensing or multiple positions.
Documents to review for Magnetic Stirrer
Because Magnetic Stirrer selection includes required speed range and stability at low or high load, no orderable model specification is inferred from this page and the quotation must identify the applicable technical document.
