Dear Elaine:

Try Enritech Enrichment Technologies Ltd. in Rehovot (Israel). They provide
a variety of 18O labeled waters at reasonable cost (at least they did so in
1995, when I placed my last order). I don't have their shipping address,
but you should be able to find it on the net.

Cheers,

Bernhard

Dear All
I am looking for a supply of oxygen 18 labelled water ( 1-3 kg 3-
10%) to use in studies of human energy expenditure.  Any help
that anyone could give me would be appreciated.

Best wishes from New Zealand
