Hotplates & Hotplate Stirrers

A hotplate stirrer combines heating and mixing in a single unit. Unlike a standard hot plate or a standalone magnetic stirrer, a hot plate and stirrer provides simultaneous, controlled temperature and agitation for greater efficiency and consistency.

Match the plate size to your typical vessels, ensure the stirring capacity supports your liquid volume and select speed ranges that allow controlled mixing without splashing or vortexing.

Yes, a hot plate with magnetic stirrer works with beakers, flasks and other flat-bottom lab vessels. For best results, use containers compatible with the stir bar and ensure stable contact with the plate.

• Increase speed gradually
• Avoid creating deep vortexes
• Ramp temperature slowly to prevent thermal shock
• Ensure the stir bar is appropriately sized for the vessel.

Clean the plate surface regularly, check for smooth rotation of the magnetic field, inspect cables for damage and verify temperature accuracy on digital models. Some lab hotplate stirrers may require periodic calibration for temperature control.

Common issues include overheating samples, using incompatible vessels, leaving a stir bar spinning unattended or exposing electronics to spills. Avoid using cracked glassware or vessels too large for the plate.

Yes, options include ceramic-coated plates for chemical resistance, digital controllers for precise RPM and temperature settings and high-capacity units for larger volumes. These upgrades improve reproducibility and safety.

Stable mixing and controlled temperature create more uniform reaction conditions. Monitor parameters such as RPM, temperature, vessel size and stir bar selection to ensure consistent results across experiments.
