Making a homemade magnetic stirrer at home is relatively simple and involves some basic materials. You will need a 2-3 foot cable of 10 gauge wire, a electric drill, a metal cup or pan, 2 neodymium or ceramic magnets, some epoxy, a small piece of wood, and some duct tape.
First, cut your 10 gauge wire into two equal pieces. Wrap each piece around the electric drill and twist it tightly at the end in opposite directions.
Second, use epoxy to adhere the two magnets to the inside of the metal cup or pan. Place the magnets in opposite directions and let the epoxy dry.
Third, attach the two unequal pieces of wire to each of the magnets. Do this by dabbing some epoxy on the magnet and then wrapping the wire around it tightly. Let the epoxy dry again.
Fourth, glue a piece of wood to the side of the metal pan. This should be thick enough to provide support and to prevent the pan from tipping over.
Finally, tape the electric drill on the side of the pan. This will help keep the drill in place while the stirrer is running and will also act as a stabilizer if the pan tips over.
Once your homemade magnetic stirrer is complete, you can place the pan with the magnets in a container of liquid and then turn on the drill to create a stirring motion. Make sure to adjust the speed of the drill according to your needs and keep an eye on the container to ensure that it does not overflow.
What are magnetic stir bars made of?
Magnetic stir bars are typically made from a ferromagnetic material, meaning a material that is weakly attracted to a magnet. The most common materials used for magnetic stir bars are metals such as stainless steel, nickel, cobalt, or an alloy that contains one of these metals.
Ferrite, a type of ceramic material, is also sometimes used. The material used to construct the stir bar must be capable of withstanding the temperatures and chemicals present in the application. Additionally, its magnetism must be strong enough to remain effective as the stir bar rotates.
Toward that end, the shape and size of the stir bar can also have an impact on its effectiveness.
Is magnetic stirrer hot plate?
No, a magnetic stirrer is not the same as a hot plate. A magnetic stirrer is a laboratory device that employs a rotating magnetic field to cause a stir bar immersed in a liquid to spin very quickly, thus stirring it.
A hot plate, on the other hand, is an electrical appliance used for heating substances, usually on the laboratory scale. Hot plates can also be used to keep substances warm over a period of time and don’t require the same level of maintenance that an oven would.
While the two devices may be used together during lab experiments, they are not the same and do not serve the same purpose.
How do you make a vortex mixer?
Making a vortex mixer is a relatively simple process. The most basic type of vortex mixers are motorized ones. First, gather all the materials you need: a motor, a strong base to hold the motor, a shaft with a fitting to attach the motor, a bell-shaped cup to hold the sample, a sample cup, and a rubber stopper.
Begin by assembling the parts together. Attach the motor to the base, then attach the shaft to the motor. Place the bell-shaped cup and sample cup inside the rubber stopper and secure it with glue, rubber bands, or tape.
Place the rubber stopper and cups into the shaft and fix it with the fastening nut and bolt. Connect the power supply to the motor.
Now, to create the vortexing action, turn the switch on the motor. As the motor rotates, it should cause centrifugal force to move the sample around the cup. This will create a vortex mixing effect. You can adjust the speed and strength of the mixing action by adjusting the power supply and speed of the motor.
When you’re done, turn the switch off and disconnect the power supply.
Vortex mixers are a great tool for mixing and homogenizing small samples quickly and efficiently. With the right materials and a little DIY knowledge, you can easily make your own vortex mixer.
How strong are neodymium magnets?
Neodymium magnets are incredibly strong. They are made from an alloy that contains a mix of neodymium, iron and boron, which gives them some of the highest magnetic fields of any type of permanent magnet.
The high magnetic strength of neodymium magnets enables them to generate a strong magnetic field even in a small size.
As a result, these magnets can be used for a range of applications that require powerful, yet light and small magnets. For example, neodymium magnets are widely used in the automotive, robotics, and aerospace industries.
The magnetic field strength of neodymium magnets can range from 2.1 to 2.6 Teslas, making them some of the strongest magnets available. Their force can reach up to 5,400 Gauss, which is approximately one hundred times stronger than Ceramic and Alnico magnets.
In addition to their high magnetic field strength, neodymium magnets also have excellent resistance to demagnetization, making them a very durable option when compared to other types of permanent magnets.
How big should stir bar be?
When choosing the size of a stir bar, it is important to consider the size of your vessel and the amount of liquid that you plan to stir. Generally speaking, stir bars should be from 0.5 – 2.5 inches long, with the most common size being 1 inch in length.
The width of the bar should be slightly smaller than the diameter of the vessel. If you are stirring a larger amount of liquid, you may want to choose a larger stir bar as it will help to mix the solution better.
When stirring smaller volumes, you can opt for a slightly smaller stir bar. Additionally, it is important to make sure that your stir bar is made of magnetic material such as stainless steel, aluminum oxide, or neodymium.
What is a stirrer?
A stirrer is a piece of laboratory equipment used to mix, blend, or agitate liquids during laboratory experiments. It typically consists of a handle with a paddle, blade or propeller-shaped head, which is made of plastic or metal.
Stirrers can be used to mix solutions of various viscosities with the intent of homogenizing them, or solutions comprising of solid material with liquids. Stirring is often done at low speeds to prevent the formation of bubbles or aerosols.
Stirrers can be handheld or attached to a motor, with the motorized version being preferred for large volume samples or viscous solutions. Stirrers may also feature a temperature sensor, allowing for mixing and/or heating/cooling, depending on the application.
Stirrers are commonly used in scientific research, such as chemistry, biology, and biochemistry laboratories.
What is a pair of husband or wife called?
A husband and wife are known as a married couple or simply a couple. In a marriage, the husband and wife commit to creating and sustaining a domestic partnership, and to supporting each other as individuals and as parents.
The marriage relationship is built on a foundation of mutual respect, love, trust, and consideration. A married couple may choose to use different titles, such as husband and wife, or they may use a shared, gender-valued term of endearment, such as “sweetheart” or “dear.
” Regardless of the title they choose, a married couple is bound by their commitment to love and honor each other for life.
What’s the purpose of stirring?
The purpose of stirring is to incorporate ingredients together while also blending in moisture and air. This helps to make dishes and drinks more evenly combined and flavorful. Stirring also helps to break apart large chunks and clumps of ingredients, such as when adding vanilla extract to a custard or stirring batter for muffins.
Stirring is also used to evenly spread heat when cooking or heating liquids, like when making soup or hot chocolate. Finally, stirring can be used to combine ingredients with food coloring, such as when making a colorful cake frosting.
What type of word is stirring?
Stirring is an adjective, used to describe something that arouses emotion. It can be used to describe a variety of things, such as a speech, artwork, poem, or event. For example, a stirring speech is one that moves people emotionally, and a stirring painting is one that evokes a strong feeling.
Similarly, a stirring poem or event may make people feel strongly, either positively or negatively. In this way, stirring is used to indicate something intense and powerful, provoking strong emotions in people.
