Yes, a very nice find. Anything new from Parr is very expensive. What is a surplus store that has such equipment?

I purchased it from a university surplus store along with a Lindberg bench top furnace. I could spend a lot of money in the surplus store since there
is a large number of other potentially useful items such as hot plates, FTIRs, to name a few items.

I found an illustration of a "Brown-Type" Hydrogenator in in Vogel's Practical Organic Chemistry Edition 5. Included are instructions. Page 91
onwards. The Original J. Org. Chem., and J. of the Am. Chem. Soc., articles.... Are pretty hard to access on line.
Brown uses NaBH4 as his hydrogen source, but any type material that releases H2 via contact with water or acid ....will do.
According to Brown, his technique is aided by the unusually active catalyst, created by the reaction of NaBH4 on Chloroplatinic Acid.
