Re: Hepes and Pipes buffer values

Dear Borries:

If you are not able to get the information you desire, you could send us
appropriate buffer samples and we could measure the densities in the
relatively near future (a month or so) and will be in a position to measure
viscosities shortly after that.  Let me know if you are interested.

Regards -

Marc Lewis
