I ordered 18O enriched water two days ago and had been informed by my
supplier that Cambridge stable isotopes discontinued to supply the the 70%+
enriched version. But they still should have a 94% enriched version as
substitution, which is, unfortunately, remarkably more expensive than the
70% enriched (especially if you have in mind that you buy a highly purified
product just to soil it...). However, he could not give me any information
regarding the time of delivery (his guess was something between one and
three months).
Maybe its still worth a try asking CSI for this product.
Yours sincerely,
Marcus Macht
