The Cost of Lab Experiments

In summary, the cost of lab experiments can vary greatly depending on the type of experiment, equipment needed, and location. It is recommended to research papers and textbooks in the desired field for price estimates. Additionally, using low-cost alternatives such as neodymium magnets, arc welders, and plasma globes can also be considered for experiments involving strong magnetic fields and plasma. However, it is important to be knowledgeable and cautious when handling these materials.

TL;DR Summary
What's the cost of lab experiments?
What is the cost of lab experiments? I do understand that it depends, but let's say it's the cost of experiments conducted in a western country involving 1) strong magnetic fields; 2) plasma.
Also, can one find price lists for such things online?
Thanks.

Sorry but this is just 'How long is a piece of string?'
If you have a particular sort of experiment in mind then search for papers in that field or look in textbooks. That should give you an idea of the equipment involved.

If you just fancy doing stuff with strong magnetic fields then you need to specify how strong. Will permanent magnets do the job? Will strong conventional electromagnets be needed? Will you need superconducting magnets. I guess there is a ratio of at least 1000:1 involved in max and min costs.

It sounds as if you are a student and you want some ideas. Let me tell you; it's the theory that comes first, then the idea about how to test it experimentally and, way down the line, the list of equipment. First time through you'll conclude that you need half a million dollars and then you modify your ideas and plan a much more modest experiment. Of course, if you plan to work in an established lab then it will already stocked with equipment that's suitable for doing the work they're interested in. So the incremental cost of a new experiment will be less. The string will already be a bit shorter.

Or if you are on a low budget, and your desired strong magnetic field is about one Tesla, then go to the hardware store and buy a neodymium magnet. Borrow an arc welder to generate a plasma, and you have everything you asked for: a strong magnetic field and a plasma. All for about $10.00 USD.

On the other hand, if you want to experiment with nuclear fusion, $10,000,000,000 should get you started.

@avpol He's joking about the arc welder. You absolutely have to have eye protection and to know all the rules about handling plasmas. You can literally fry your retina if you don't know what you're doing.

PS To avoid eye problems with high intensity arcs, do what I saw a guy on YouTube did. He used his smart phone camera, pointed through a hole in some board and was happily welding away with no danger and the picture was perfectly exposed. Not sure how long the camera lasted but spots on a retina are worse than spots on an imaging chip.

Another low cost possibility ($50) is a plasma globe, such at this one (randomly picked after searching plasma globes): https://www.arborsci.com/products/8...MIitXl0_-b-QIVmB6tBh2Hgw21EAQYAiABEgLoWvD_BwE.

A sample quote from the instruction sheet:
Use the plasma globe to study plasmas and electrical discharges.

A sample activity from the datasheet is given below.

The first thing you and your students will notice about the sphere is that by placing a conductor (your finger will do nicely) near the surface of the globe, the streams of plasma seem attracted to it. Since the plasma streams are composed of ionized gas molecules, these charged particles are attracted to an uncharged object, similar to the way a charged balloon is attracted to a neutral object (like the wall of your room). You may want to encourage your students to experiment and see if they can attract more streams with different types of conductors or insulators. (How about a magnet?)

I know that colliders are expensive, but they are absolutely out of the scope of my interest:-). That's why I mentioned magnetic fields and plasma (and no particles:-)).

The main reason to consider that cost is to know the rough upper bound of what an experiment can cost. These experiments are pretty much as expensive as it gets. Everything else is cheaper.

I’d say most *individual* academic and/or government research groups in the US have an annual budget of between a few hundred $k and a few $M. Much of that money goes to personnel (can range from a few grad students to dozens of students and staff scientists) and overhead. Lab equipment and supplies can run from a few thousand dollars a year to hundreds of thousands (as a general rule, chem and physics labs are cheaper; bio labs are more expensive, and god help you if you want to do animal research), but usually people share/buy time on really expensive instruments, which are often paid for with some sort of departmental fund (think an X-ray diffractometer or an electron microscope: really nice ones can be over $1M, but usually end up in a shared facility). This probably isn’t out of the ordinary for plasma physics (NB—I’m not in that field), unless of course you want to do something really high energy or large-scale like fusion.

The fact is, I know about a startup raising funds for a project that involves both theoretical and experimental work in the field of physics. I know more or less how much the theoretical part costs, but I know nothing about how much experiments may cost. That's why I asked:-).

Just read their business plan. All such costs will be detailed in the business plan for a startup.

Of course I would read it if I had access:-). I just know it's connected with propulsion systems for space industry; an exact solution isn't chosen yet, but magnetic fields and plasma are considered among other options.
From what I've read in this thread I dare conclude it won't be extremely expensive.

What is the cost of conducting a lab experiment?

The cost of a lab experiment can vary greatly depending on the type of experiment, materials needed, and location. On average, a basic lab experiment can cost anywhere from $100 to $500. However, more complex experiments can cost thousands of dollars.

What factors contribute to the cost of a lab experiment?

The cost of a lab experiment is determined by several factors, including the type and complexity of the experiment, the materials and equipment needed, the location of the experiment, and any additional costs such as participant compensation or data analysis.

How can I reduce the cost of a lab experiment?

There are several ways to reduce the cost of a lab experiment. One way is to use alternative, less expensive materials or equipment. Another way is to collaborate with other researchers or institutions to share resources and costs. Additionally, planning and budgeting carefully can help to minimize unnecessary expenses.

Are there any hidden costs associated with lab experiments?

Yes, there can be hidden costs associated with lab experiments. These can include unexpected equipment failures or repairs, additional materials needed, or unforeseen complications that require additional time and resources. It is important to budget for these potential costs when planning a lab experiment.

What are some ways to obtain funding for lab experiments?

There are various ways to obtain funding for lab experiments. These can include grants from government agencies or private foundations, crowdfunding, collaborations with industry partners, or seeking funding from the researcher's institution. It is important to carefully research and apply for funding opportunities that align with the goals of the lab experiment.
