PureSperm Wash – 100 ml
A three-in-one product.
PureSperm Wash has been optimised to serve various different purposes. This one product can be used for washing the sperm pellet recovered after density gradient preparation, for use in swim-up procedures, for extending the sperm prior to Intra Uterine Insemination (IUI), and as a maintenance medium.
- Thanks to its stable formulation, PureSperm Wash has a shelf-life up to 1 year.
- PureSperm Wash does not contain any colouring agents or preservatives, both of which can be toxic to sperm.
- PureSperm Wash is a sterile isotonic salt solution.

When should PureSperm Wash be used?
We recommend PureSperm Wash for washing the sperm pellet after centrifugation using a PureSperm density gradient. The ionic balance of PureSperm Wash lies between that of the gradient and commonly used fertilisation media and, therefore, will not cause premature hyperactivation of the sperm. PureSperm Wash is also ready-to-use and contains an appropriate level of human serum albumin.
What are the constituents of PureSperm Wash?
PureSperm Wash is an isotonic (290-300 mOsm/kg H2O), HEPES-buffered salt solution containing glucose, EDTA, and human serum albumin.
Is there any protein in PureSperm Wash?
Yes. Research in our laboratory showed that human serum albumin must be added to the PureSperm Wash to prevent sperm sticking to plastic-ware and microscope slides.
Are antibiotics included in PureSperm Wash?
No, PureSperm Wash does not contain antibiotics. First of all, antibiotics commonly used in cell culture media are toxic to sperm and the gradient will remove most, if not all, of the bacterial contamination present in the ejaculate, provided that the retrieval of the sperm pellet is carried out according to the instructions given in the package insert.
Should PureSperm Wash be refrigerated?
PureSperm Wash is supplied as a sterile solution which does not need refrigerated storage in the unopened bottle. After opening (under sterile conditions), however, PureSperm Wash should be kept at 2-8°C.
