High concentration blood products have advantages in purity and without sugar stabilizers, which are closer to human physiological osmotic pressure. They can ensure good infusion tolerance, shorten patient infusion time and reduce adverse reactions. Therefore, ultrafiltration and concentration of high concentration blood products has become a hot topic. Single-pass tangential flow filtration (SPTFF) can achieve in-line concentration of high concentration blood products due to its compact design and can reduce the concentration reduction caused by buffer dilution.
