Source of 11boron isotope

[Jean-Michel Mignot]

Some time ago, I posted the following question:

>Could anybody suggest commercial sources of 11boron isotope with at least
>99.5% enrichment?

Many people answered to me directly. Here is a summary of their suggestions:

I read your mail looking for 11boron isotope. I use 11boron isotope to make
single crystals (...) for neutron measurements. It was purchased from
Isotec inc., USA and isotopic enrichment is 99.50 atom %.

A good possible source of B11 is Eagle Picher. They may have European
subsidiaries, but you can call +1 918 673 2201 and speak to Bill Hawk. The
last quote I had was $16.50/g, with a minimum order of $300 US.

One of the biggest sources of Boron isotopes is Eagle-Picher, they are
American but they have a sales office in Germany.

We have a brochure with B11 advertised at 99.5%.  The company name is:
Penwood Chemicals Inc. 98 Cuttermill Rd.  Suite 262, Great Neck, NY 11021,
Tel USA 516 487 2077    Fax 516 487 2890.

#Could supply only isotopic *boric acid*. Suggested Eagle-Picher.

================

I checked myself and found that Isotec also has an office in Europe:

Nippon Sanso Europe GmbH, Division Isotec, Inc. USA
4 rue des Freres Lumiere
78370 PLAISIR
France
Tel. +33 1 34 81 18 18
Fax + 33 1 34 81 18 19

However, the best offer was that of Eagle Picher (see above). The
enrichment may vary since their quotation was only for ">99%" but in my
case they could offer 99.5% at the same price.

Many thanks to all those that answered my question,
