Re: Isotec light water.

Dear Tim,

below is the desired information. On the label of each 1-liter
bottle is written:

WATER, DEUTERIUM-DEPLETED  < 0.5 PPM D
Cat. NO. 602744
LOT NO.  CR1552

I believe the last number is the one you want to know.

The same information is also written on the certificate of analysis,
where is states in addition:

  METHODS             SPECIFICATIONS                TEST RESULTS
Isotopic Enrich.   Maximum 5 x 10e-05 atom% D    Meets requirement

Best regards

Claude
