Hello all,

I have recently pulled apart in effort to repair a photoreactor.  Inside is
a high intensity UV tube, very similar in appearance and identical in
operation to a florescent tube.  This tube lacks any coating.

Apart from the warning the only identifier is the code "P5V".  It is about 5
feet long and smaller diameter than "standard tubes" of about 1/2 inch.

If anyone can aid me in my goal to find a) who makes it and b) its emission
spectra it would be appreciated.

Cheers

Mike

Start here, perhaps the bulb is made by one of these:

Have you tried the equipment manufacturer? Do a Google search for the
brand name.

If you are referring to UV curing or similar application then try a
company such as http://www.caprockdev.com/uv_lamps.htm and see if they
can assist.

Thanks to all. From sources here and otherwise I am confident that the tube
will sadly be no good for the application.  But I don't think it will be too
much of a drama to replace with a more useful tube.

Cheers

Mike

Sounds like a "Germicidal" Tube....sorry about the spelling but pronounced
"Germ - e - side - el"
They use these things in Medical Sterilising equipment.
They pump out Heaps of UV and are quite dangerous if you look at them while
the are running.
The UV levels are high enough to damage your eyes.
I once used one in a home made EPROM eraser.......
But even inside a light tight box, I used to put the thing in the closet
when it was running in case someone was tempted to open the box (should have
had a safety switch).
I would erase a whole tray of EPROM's in about 5 mins Flat.........
I got the tube from Auslec, an electrical wholesaler in the town I used to
live.
The tube was about a Foot long 10w?? maybe and clear glass.
Cost about 30 bucks from memory.

cheers
John
