Users report that NAD+ solutions can be viscous and resist filtering even after dilution attempts. Suggestions include using larger 13mm filters, venting the target vial, removing all air from the syringe, and checking for undissolved particles. One person succeeded with 1000mg in 5-6ml BAC water through a 0.22 micron filter while another traced the problem to a specific kit after other batches filtered normally.
What this discussion establishesNothing here is advice.
Whenever I try filtering my peptides the NAD+ refuses to go through at all. Switching to other filters and using more BAC water to thin the solution hasn't changed anything. Any ideas on what's happening?
I've been dissolving a gram of NAD+ into five milliliters of bacteriostatic water before sending the mix across a 0.22 micron filter without running into any trouble.
Got it, thanks. My one seems to have a different problem.
I wonder if the consistency is meant to have lumps. Placing a bit on absorbent paper let me spot any particles that remained undissolved.
Is air what you're trying to force across? Having air trapped in the syringe stops things from moving past the filter without trouble.
Two things I've done include making certain the destination container can release air pressure and going with a filter at least thirteen millimeters across rather than the smaller size. That approach has always worked without any trouble for me even at 1000mg NAD+.
I always vent using the 13 millimeter filter on the remaining peptide compounds in my collection. Each of them operates correctly except nad plus.
Actually I remove every trace of air from the syringe ahead of filtering.
Sometimes the NAD appears to thicken up noticeably. It's still flowing inside the container for certain, yet getting it pulled into the syringe always ends up tricky.
Every once in a while my filters give me issues. I push hard again and again until after a bit the liquid finally moves through. I can't tell why this occurs but it happens at times.
Bad filter?
Yeah it's thick. This also affects the total volume. Mixing a thousand milligrams into six milliliters gave me roughly seven milliliters of the NAD+ solution. It filtered okay with the 22.
I've been relying on certain filters but tested alternatives purchased online too. Comments in this discussion suggest the thickness might be causing issues. I'll attempt to adjust for that. Additionally, some fresh NAD+ is on the way, so I'll observe the results with that as well.
I could pass the item back through the filter to check whether it works.
I should add that I recently bought two lone NAD+ vials from a different seller. Filtering worked on them, meaning the problem lies with my current kit. That's a shame. I'll probably just write it off as gone.
