Before I learned how to work a turkey baster, I ended up with particles of soup and my extract as well. My advice to you at this point is to simply re-crystallizer extract. If you lose a portion of the full spectrum, then so be it but I kinda doubt you're going to lose much of the NMT.
Next time, just be a little more careful with your pulling, and, just as grateful one suggested, use two vessels to decant from your soup. Drop your pulls in vessel number one and allow any sediment to fall to the bottom.
By the time you finish and are ready to do your next pull, just simply carefully pour off – do not use a syringe or a baster – the NPS into your final precip/evap dish.
This two-step process has eliminated any need for recrystallization for me. That and learning how to steady my hand.
Many happy returns to you. Good luck in your future efforts.
