How to Use a Digital Magnetic Stirrer with Hot Plate | Step-by-Step Lab Guide

Description:
Welcome to our laboratory tutorial!
In this video, I will show you how to properly use a digital magnetic stirrer with a hot plate in a chemistry laboratory.

We will cover:
✅ Basic parts of the digital magnetic stirrer-hot plate
✅ How to set up your glassware and stir bar
✅ How to adjust stirring speed and temperature
✅ Safety precautions you must follow
✅ Tips for best performance and maintenance

Materials Needed:

Digital magnetic stirrer with hot plate

Beaker or conical flask

Magnetic stir bar (flea)

Thermometer (optional for accurate temp)

Chemical solution/sample

Step-by-Step Process:

Preparation:

Place the digital magnetic stirrer on a flat, stable surface.

Ensure the device is clean and dry.

Placing the Stir Bar:

Drop the magnetic stir bar into your beaker or flask containing the liquid.

Center the vessel on the hot plate.

Starting the Stirring:

Switch ON the device.

Set the desired stirring speed using the speed control knob or digital panel.

Start at low speed to avoid splashing.

Heating the Sample (Optional):

If heating is required, slowly increase the temperature setting.

Always monitor your sample to avoid overheating or boiling over.

During Operation:

Watch for stable vortex formation in the liquid (shows proper stirring).

Adjust speed and temperature as needed.

After Completion:

Switch off the heating and stirring functions.

Allow the device to cool before removing the vessel.

Clean the surface of the hot plate after
