Replacing columns for a solvent purification system.I am a graduate student at Baylor University who has been put in charge of maintaining our solvent purification system. This system looks nearly identical to the pictures posted on your website. I have a few questions: 1. Can you replace the desiccant in our columns if we ship them to you? if so how much does this cost? 2. Can we buy desiccant and refill the columns ourselves? We will buy it from you guys if the answer is yes. 3. Is it possible to reactivate the desiccant in a column if it becomes saturated with water but has not lost any structural integrity? 4. We can easily bypass the columns on our system by attaching the keg directly to the dispensing bulbs but have been too timid to put this into practice. Are there any problems associated with transferring dry solvent to the keg and using our system to dispense it? I would greatly appreciate if someone answers any of these questions or refer me to somewhere that I can search for the information. -Thank You, Josh.Replacing columns for a solvent purification system.I am a graduate student at Baylor University who has been put in charge of maintaining our solvent purification system.

Hi Josh, Thanks for reaching out, yes, we can take care of your columns. If you send them back we[...]





I am writing to you in regards to a SPS system installed in the Department of Drug Design and Pharmacology at University of Copenhagen. As far as I know, the system was installed in 2011 and it’s been running on originally supplied columns since then. 1. I would like to ask whether the columns should be replaced with new ones? We don’t have easy access to KF titration to measure the water content. Estimated amounts of solvents that passed through the columns since 2011 are: THF-150 liters; DCM-170 liters and DM-130 liters 2. Please also indicate if there is a local representative, we can get in touch with in order to purchase new columns and reservoirs?I am writing to you in regards to a SPS system installed in the Department of Drug Design and Pharmacology at University of Copenhagen.
