1. If you don’t have a magnetic stirrer with a heating facility, keep the solution in a 60C water bath and occasionally swirl the solution. This can take a long time. 2. A slightly alkaline pH is required to dissolve the paraformaldehyde completely in the solution. Since the pH of PBS is around 7.4, paraformaldehyde dissolves easily in the PBS.
2. Turn on the magnetic stirrer by flipping the power switch on (–), then rotating the left knob in a clockwise direction. 3. The farther you rotate the knob, the faster it will spin to stir your solution. You can control the stirring speed between about 120 and 1400 rpm. The magnetic stirrer can be used with or without the hot plate on. 4.
A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).

Finally like agitator, To make it rotate inside the containers we will use a ferrite magnet. And that's it. We have our agitator. A possible improvement would be to put a potentiometer or regulator, to choose the speed at which we want the stirrer to rotate. A video of the magnetic stirrer in operation. https://www.youtube.com/watch?v=RO1LYgzZx04
For many experiments, on all those related to chemical products, a magnetic stirrer. So here we bring you how to make a homemade magnetic stirrer As you can see, we will use a fan from a PC source to which a neodymium magnet from a hard disk is attached.

Sep 17, 2021 OK, so I watched the video on YouTube on how to set up the magnetic stirrer, but I don't think I did it right. This is what I'm trying to accomplish: I want my doser #11 to dose every Sunday @ 7.15am - 20ml; I want the magnetic stirrer to stir 1 min prior to dosing.
Step 1: Glue the Magnets to the Fan. Prepare and clean the fan for use. Your fan may have two wires (red for positive and black for negative). If it has three wires, the white wire is a tachometer and is not needed. Glue the magnets on opposite sides of the fan head.
Step 4: Assemble. Figure 1: To assemble, I placed the fan under the griddle. Thankfully the griddle is aluminum so the magnetic field lines from the rare Earth magnets will penetrate the griddle. I did have to double up the magnets as was seen in step 2 in order for the stir bar to be affected by the magnets on the fan.

This magnetic stirrer for spectroscopy uses a magnetic field to transmit torque to a Teflon coated magnetic bar inside of a sample cell. Due to its small size, the stirring bar fits into even 2 mm thick cuvettes. Since the rotation of the stirring bar is achieved with a magnetic field the stirrer can be used with hermetically sealed cells.
