I have looked back over the archives about this and have found some
information but I am not really clear on whether or not local grocery or
drug store mineral oil is acceptable for my Leeds & Northrup 10 ohm standard
resistor.

I emailed Ohm-Labs (that I think maybe acquired Leeds & Northrup?) and they
suggested Drakeol 7 or Blandol. However, I can't find a source for it.
They suggested Fisher Scientific or VWR but I can't find either brand listed
on their websites. They do list 'light mineral oil'.

Any information or suggestions appreciated.

Failing finding the right stuff, try an simple experiment:

Get a bottle of the stuff (laxative aisle of your local drug store) and
pour it into a very clean jar and take a couple of long SS screws as
electrodes and see if you can measure any leakage resistance.

Maybe not a volt-nut approach, but workable but certainly good enough for
a 10 Ohm standard.

FWIW,

Pete,

I actually saw both of those. It was not clear that they sold small
quantities. Nothing ventured....

So I emailed them. We'll see what they say.

Plain mineral oil from the grocery is so much more available:).

Hi Joe,
You don't say were you are, but I guess the USA. Light mineral oil USP or Liquid paraffin USP (different name, same thing) from your local Pharmacy is what you need. also see ebay items 260881466334, 260881466408 (no connection with or knowedge of the seller).If you need larger quantities try animal supply or food manufacture suppliers.

Pay a visit to your neighborhood substation some night w/ a bucket. :))

Seriously, you might ask your local utility for a cup or two.

It's just pharmaceutical light mineral oil. It is the same stuff
you can buy from Tractor Supply Corporation, or Southern States in
gallon jugs for $15... or from your grocery store in smaller quantities
for a higher price.

What you probably should avoid is baby oil, which is light mineral oil
with perfume added.

Thanks for everyone's reply. If all it takes is just plain old Mineral Oil,
I can get that easily at the local grocery or drug store.

Mitch, have you received the Drakeol yet?

I also have a Leeds & Northrup 0.1 ohm and a GRAY Inst. Co. 10000 ohm
Standard Resistor, both of which came with oil. Their oil, though, is very
dark with quite the odor. Somehow, I don't think plain old Mineral Oil is
quite the same. If it is an acceptable substitute, I can certainly get it
very easily.

I had always thought the oil was as much for elimination of moisture as it
was for insulation. Also, of course, it seems to be for the purpose of
adding some 'thermal mass'.

I have looked back over the archives about this and have found some
information but I am not really clear on whether or not local grocery or
drug store mineral oil is acceptable for my Leeds & Northrup 10 ohm
standard
resistor.

I emailed Ohm-Labs (that I think maybe acquired Leeds & Northrup?) and
they
suggested Drakeol 7 or Blandol. However, I can't find a source for it.
They suggested Fisher Scientific or VWR but I can't find either brand
listed
on their websites. They do list 'light mineral oil'.

Any information or suggestions appreciated.

Joe
