Dear Richard,
It has been over 6 months since our department has purchased the Autopol IV Polarimeter from Rudolph. I wanted to let you know that we have been extremely pleased with the performance of this instrument, in terms of sensitivity and reproducibility. The instrument is very robust, and the stainless steel jacketed cells are truly a bonus, unlike the old glass cell. these are very user friendly and forgiving, especially when handled by clumsy graduate students! I wanted to thank you for working with us on this purchase; and we hope to do business with Rudolph again in the future.
Sincerely,
Dr. John M. Rimoldi
Associate Professor of Medical Chemistry
