Collection: Magnetic Stirrer

Magnetic stirrer is a laboratory instrument for stirring solutions automatically and evenly. A plate beneath the vessel rotates a magnetic field, which then drives a PTFE-coated stir bar inside the beaker or flask. Because no mechanical parts enter the solution, stirring is clean, stable, and easy to reproduce.

This page offers magnetic stirrers and hotplate stirrers (magnetic stirrers with heating) from Joan Lab and Biologix, ranging from mini models for small volumes to large-capacity and multi-position models.

Types of Magnetic Stirrer

  • Mini magnetic stirrer: compact, for small volumes and routine work on the lab bench.
  • Hotplate stirrer: stirs and heats at the same time, suitable for dissolution, synthesis, and media preparation.
  • Multi-position (4, 6, or 9 positions): stirs several samples at once under uniform conditions.
  • Large capacity (10–100 L): for mixing large volumes in production laboratories or pilot plants.

How to Choose a Magnetic Stirrer

  • Maximum volume: match it to the largest vessel you commonly use.
  • Need for heating or not: choose a hotplate stirrer if the process requires controlled temperature.
  • Speed range (rpm): viscous solutions require better torque and speed control.
  • Digital display: makes it easier to set precise and repeatable speed and temperature.
  • Number of samples: multi-position models save time and bench space for parallel testing.

Frequently Asked Questions

What is the difference between a magnetic stirrer and a hotplate stirrer?

A magnetic stirrer only stirs. A hotplate stirrer stirs and heats the solution at the same time, so it suits processes that require a specific temperature.

Is a stir bar included?

Included items vary by model. PTFE magnetic stir bars are also available separately in various sizes and shapes.

Can it be purchased for institutional procurement?

Yes. AMI Scientific serves procurement by government agencies, universities, and industry, and is registered in the LKPP e-Katalog. An official price quotation can be requested through our team.
