Hi, I am new to this forum but I am an applied physics student and I'm working on a seminar on deep space spectroscopy. My question is actually on the equipment being used for my research. I am using an SBIG ST-7 camera with a DSS-7 spectrograph and I've been running calibration studies with...

I have a large lot of beakers, tubes, various types of lab glass that was left to my friend when his brother died. Nobody really understands what most of it is for, but I have agreed to help them dispose of it. Ebay seems an unlikely choice as this stuff would probably break in shipping; Can...

ok, now this is crazy. the story, obviously, is that "A truck carrying President Obama's Presidential seals, podiums and $200,000 worth of audio equipment is stolen north of Richmond." but what about the part that is left unsaid? that is, equipment that sits around unguarded for days. would...

I'm an astronomy teacher on a very tight budget. Before I really get into the meat of astronomical information, I want to make sure that my students have some understanding of WHY it is that we know what we do about astronomical bodies, and that means getting them to work with some of the tools...

Back again to ask another question about test equipment. I'm very new at this so please bear with me. I'm trying to work through this https://www.amazon.com/dp/0521646456/?tag=pfamazon01-20. In order to do a lot of the exercises in the book I need access to an oscilloscope, function...

I am in need of constructing a heater probe for a reaction chamber. I need to put out a maxium of 500 Watts continuous from the 5 cm end of a probe of either 1/4" or 5/16" in diameter. I am constrained to either of these standard sizes. My first inclinations are to wind nichrome wire...

I am rather familiar with qualification of electrical equipment in nuclear power plants (such as IEEE 323, IEEE 344 etc.). However, a extensive web inquiry about qualification of mechanical equipment did not yield any results (beside ASME NQA-1, which seems to discuss general quality...

I am currently in the process of updating my CV. When listing the various equipment I have worked with, should I list the make/model etc.? For example, I have worked with a Molecular Beam Epitaxy system. Should I list, I have 5 years experience working with a custom-built SVTA MBE system, or...

I'm surprised we don't have an Equipment category on PF. Much of working with Physics is equipment for monitoring, testing, calculating, etc. Then there's not just the equipment (hardware) but software, operation, source of supply, repair, calibration, rentals, etc. So let me throw that in the...

I'm a beginner at this but I'm an aspiring student of the electrical field. Electrical engineer, electrician, electronics technician. I like it all. My question is what equipment, other than what I know already, do I need to run as much of my house off of wind power? Wind turbines or...

We have this thing about naming equipment in the office. The printer/copier/fax is called Diablo II or Spawn of Diablo. It's a cranky machine that responds well to voodoo offerings like shiny pennies, red ribbons, and chicken bones. It is not nearly as troublesome as Diablo I. Then there's...

Hi. I would like to purchase some physics equipments, such as magnets, mirrors, circuits, ammeters/voltmeter, etc., for my own physics project. I don't know where to look. Do you guys know of a website that sells any physics products? Or can only a licensed professional purchase them?

As the title states, I've been having trouble figuring out how to run a certain large dryer for corn and rice due to the available supply in our locality. The dryer is a modular equipment that runs at a total of 30-hp and requires a 440V, 3-phase supply. The only available supply is 230V...

hey, just bought this interesting piece of laboratory equipment, but i have no idea what its used for. the 4 meters on front panel measures peak control, integrator, and count rate (x2) potentiometer knobs is saying; high voltage, underneath the peak control meter, under the meter...

I'm working at a small company (less than 10 people), and I need to purchase some high end equipment I know nothing about... Brings back memories from grad school. I've been here less than two weeks. In the past I educate myself on the equipment, and figure out what the relevant...

I'm working for the physics department this summer and I've been tasked with cataloging our equipment room. Part of this job involves identifying equipment used by previous professors but that no one knows about anymore. Could I get assistance in identifying some of these items or the labs...

Hey Working on a rather large project and it's the first time I've had to look into the world of pressure sensors. Basicly, we're looking into measuring flow levels in small rivers, either in areas where we build a profile to gather up the water and in natural areas where there's no need...

Does anyone know the full specs for those pump argon lasers used in the quantum eraser experiments? We're can I buy a used one? Also, is there a good place to buy the other equipment (lenses, crystals, etc) needed to perform the experiment? thanks! Lux

This is a (video?)camera I found in a box of my father's things. These were taken on my cell phone - sorry for the poor quality. How old do you think this device is?

Hi, I am a Kenyan scientist/academic and in dire need for equipment that is no longer in use in laboratories in the west. I have without success written to manyinstitutions in the UK requesting to acquire the equipment they no longer use eg old PCR machines, Centrifuges etc, but I have not...

So I'm mostly talking about things like digital thermometers that i can use everywhere, pressure gauges, humidity sensors, and chemical sensors (especially sensors of CO2 levels, O2 levels, particulate matter levels, and maybe things like decibel sensors). Just for plain curiosity. :) Thanks!

Hi I have a problem in detecting whether string is vibrating or not. I'm going to conduct experiment which will investigate impact of different factors on time of decaying of guitar's string oscillations but I have no idea how to measure when oscillations stopped. Acoustic method doesn't work...

You are designing a delivery ramp for crates containing exercise equipment. The crates weighing F_1 will move at a speed of v at the top of a ramp that slopes downward at an angle \phi. The ramp exerts a kinetic friction force of F_2 on each crate, and the maximum static friction force also has...

Can anybody give a rough estimate of price for a chemical Vapour deposition equipment to make carbon nano tubes? How much budget do we need to establish a laboratory to make carbon nano tubes?

I have a question as to what container I can use to do the extract a drug from a solvent layer in. (via shaking with another solvent) The problem is that there are no conical vials in the lab and we can't borrow any. We do have test tubes, however the covers for the test tubes leak and thus...

I am looking for a data acquisition system to replace an old Spectral Dynamics Siglab 42-20 system that I use to collect the frequency response of a smart material actuator our company manufactures. We currently run a stepped sine test between 50Hz and 2000Hz. This tests dwells at 50Hz, collects...

I was given a 3 phase plasma cutter (no motor in machine only transformers)and my garage is only 1 phase. I have been doing a little research on converting 1 phase to 3 phase but it is just to expensive for my budget! I did come across an article that suggested that is can be done without a...

Hi all, I was looking for a way to oscillate airflow at a particular frequency as fed from an electrical input. All I'm really looking for is a simple knife gate valve that opens and closes from a saw tooth (rectangular wave) input from an oscilloscope. I was thinking a Solenoid valve...

Hello PF. I'm building a circuit that uses triacs to switch power on and off for a series of devices. However my teacher warned me that Triacs basically skip the zero part of the waveform, and that can affect digital devices, such as my computer. I'm looking for a more in-depth explaniation...
