We had a (Other Brand) before too, and have changed to Rudolph Autopol IV for about a year. We are pleased with the Rudolph Autopol IV ….
…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 cells, these are very user friendly and forgiving, especially when handled by clumsy graduate students!
We like the Rudolph polarimeters—they are very robust…our School of Pharmacy has fully converted to Rudolph, based on specifications, price, and support.
…after evaluating various polarimeters from well-known manufacturers, we ended buying one from Rudolph Research…This letter is to confirm that we are very pleased doing business with your company.
I have used numerous polarimeters and this is by far the best. We have had it for 1 ½ years and have had zero problems; the original lamp is still in the instrument. I recommend it over other instruments…we have had no problems. It is one piece of equipment that you never worry about.”
