Solvent Column Replacements
Proprietary activation for the driest solvents in the industry.
When your research success depends on the driest anhydrous solvents, PPT delivers with secure, expandable purification systems that reduce risk, improve safety, and cut the hidden costs of outdated distillation methods.
SOLVENT PURITY MADE SIMPLE
How Solvent Purification Systems Work
SPS removes water and oxygen from solvents as they pass through purification columns into a vacuum-sealed glass flask. An argon blanket protects the solvent from re-exposure—keeping it reliably anhydrous for hours of use.

Safety & Performance Benefits
Eliminate Cross-Diffusion of Solvent Vapors
For academic researchers and laboratories working with organic solvents, the risks of handling large quantities of flammable material are serious. Traditional distillation methods increase the chance of injury and costly damage. Pure Process Technology’s column-based purification systems reduce these risks, ensuring consistent results and a safer laboratory environment.
Reduced Risk of Injury & Damage
Traditional distillation increases the chance of fire, injury, and costly lab damage. PPT’s systems are engineered to minimize these risks, providing a safer working environment.Consistently Driest Solvents
Our proprietary column technology ensures your lab has access to the driest anhydrous solvents available—reliably and repeatably—so research outcomes aren’t compromised.Confidence in Every Experiment
With safety secured and performance guaranteed, your team can focus on advancing research instead of troubleshooting solvent quality or worrying about lab hazards.

Choose the Right SPS for Your Space and Safety Needs
Every lab has different space, safety, and throughput demands—but the need is the same: the driest, most reliable anhydrous solvents. PPT’s modular SPS platform lets you choose the footprint and enclosure style that fits your room, expands with your research, and delivers industry-leading low PPM water levels—day after day.
Cabinet Mount Systems
Our most popular configuration between 3-5 solvents with a compact footprint that saves valuable lab space
Hooded System
When mandated hood installations require the highest-performing solution.
Free Standing System
When expanding research needs require the highest-performing, scalable system.
Compact System
When the tightest spaces require the highest performing system.
System Customization
We offer compact, hooded, cabinet mounted or freestanding system, as well as assisting with plumbing your SPS into a glove box. We can work with your space and lab requirements.Installation and Training

Refilling columns requires lab down time.
It is less expensive, $950 per set of 2.
You will have to remove and empty and ship the columns to our Nashua NH location. We will process them and ship them up via freight to ensure safe transit and get them back to you.
Please see how to safely remove and replace your columns HERE
You will need to Provide list of Solvents and handle color assignments to PPT
Replacements $1450 per set of two
With replacement columns, there is no Lab downtime, you can receive new columns ready to go at your convenience and you can return the old columns to PPT in the shipping container you received your new columns with the return shipping label provided.
For either case, please provide list of Solvents and handle color assignments to PPT
What type of Solvents are needed for the system to produce the best results possible?
We don’t have a preferred vendor list, we recommend using HPLC or ACS grade with < 100 PPM of water content (unstabilized) noting some solvents have specific requirements
For DCM, we do recommend JT Baker Cat #9315-03 which is DCM quality DCM stabilized with Cyclohexene
Seal/Leak: Check Kegs for rust, contamination and leaks-you can try replacing the o-ring/seal, the lid, or you may need to replace the keg.
Rusted Keg: The keg for dichloroethane appears to be rusting, and the keg lid no longer seals properly, causing argon to leak from the keg. I am writing to inquire about replacements for the lid, and possibly the keg if necessary
Empty and clean the keg using 409 or Simple Green and a scour pad. If you can send us some pictures of the keg we can assess it for you. Unfortunately, DCM is known to cause corrosion due to the HCL gas produced from it. If the keg cannot be saved, we can quote a 316L Keg and recommend JT Baker DCM# 9315-03 stabilized with Cyclohexane, that will work best to prevent corrosion if that can work for your chemistry.
If you are noticing that your solvents are wet, you need to wait at least 48hrs after saturating the columns. Purge about a flask’s volume before testing.
If you are noticing a decrease in the pressure of restricted flow of your solvent dispensing, Check the pressure gauge from your Argon tank to the system.
Reminder, with DCM you need to put a little more pressure on the system, around 12psi should work, and it can be bumped up to 13. Do not go above 14psi.
Another checkpoint is making sure you are closing the bottom valve on the back column when not in use. If not, solvents may be draining back into the keg and causing issues.
If you are noting a decrease in the pressure:
- Remove and clean/replace the final filter
- Blow compressed air through backwards
- Sonicate it and put it back in
Additionally, leaks at the keg can impact flow. If you have recently filed the keg, check that the o-ring is still good and that you have a tight seal. Confirm you follow the proper procedure

Frequently asked solvent system questions
Still Have Questions?
We’ve answered the most common ones below—but if there’s something else on your mind, we’re just a message away.
We are often asked about recommended solvents, you may use any un-stabilized ACS or HPLC Grade Solvent with <100ppm of water content
For DCM please use JT Baker# 9315-03 stabilized with Cyclohexane, anything else will corrode your solvent keg.
Your only option is stabalized ether.
If the system is older, you’re probably in need of a column replacement. For a new system, please contact us.
If you are noticing a decrease in the flow of your solvent dispensing, Check the pressure from your Argon tank to the system by:
Checking the pressure you are running the system at. Reminder, with DCM you need to put a little more pressure on the system, around 12psi should work, and it can be bumped up to. Do not go above 15psi without consulting with PPT first.
Another checkpoint for DCM is making sure you are closing the bottom valve on the back column when not in use. If not, solvents may be draining back into the keg and causing issues.
If you are still noticing a decrease in the flow you can check our instructions for cleaning the filter. If the problem persists, please contact us.
Your lid 0-ring is probably leaking. Try removing the o-ring, cleaning and sealing the surface and reinstalling it with a light coat of Krytox Grease.

Columns have 600-800 liters of capacity / or 5 years. We recommend keeping a log of how much solvent they take so you know how much has gone through them.
