Achieving consistent, high-quality sperm preparation results depend heavily on maintaining optimal sample conditions. Two common challenges—rising osmolality over time and high semen viscosity—can compromise sperm function and reduce recovery rates. PureSperm™ Buffer provides an effective solution to both issues, supporting smoother workflows and more reliable outcomes.
Stabilize osmolality for improved sperm function
After ejaculation for collection, and not in vivo, the combination of all fractions leads to increased osmolality, which can negatively impact sperm motility and viability. Early stabilization of the sample environment is key. PureSperm™ Buffer is formulated to maintain physiological osmolality, helping protect sperm cells from osmotic stress and supporting better performance throughout processing.
Reduce viscosity for easier handling and higher yield
Highly viscous semen samples can be difficult to process and often lead to lower sperm recovery. PureSperm™ Buffer helps reduce viscosity, making samples easier to handle and improving the efficiency of downstream preparation steps. By promoting a more uniform and manageable sample consistency, PureSperm™ Buffer supports improved sperm yield and more predictable laboratory results.
