INFORMATION
40 % (v/v) and 80 % (v/v) ready-to-use gradients.
Application
SpermFilter® is a silane-silica based density gradient medium
used in ART for separation and purification of highly motile
human spermatozoa. Composition
SpermFilter® is composed of silica particles covalently
coated with silane and resuspended in isotonic phosphate and
Hepes buffered saline. SpermFilter® ready-to-use
gradients are diluted with SpermWash® (Hepes buffered isotonic
medium with Gentamicin). Quality Control:
80 % (v/v) SpermFilter®
gradient
- pH: 7.4 ± 0.2 (25º C)
- Osmolality: 300 ± 10 mOsm/kg
- Endotoxin: < 0.1 ng/ml (<1 EU/ml)
- Sterility test

gradient
- pH: 7.4 ± 0.2 (25º C)
- Osmolality: 290 ± 10 mOsm/kg
- Endotoxin: < 0.1 ng/ml (<1 EU/ml)
- Sterility test
Shelf Life
One year from production date when stored refrigerated
(2º-8º C). Avoid freezing. Sterility
The medium is manufactured under sterile conditions and
sterility is ensured by testing each batch. Sterility tests
verify the absence of viable micro-organism (bacteria, yeast
and fungi). Packages
The medium is supplied sterile filtered in pharmaceutical
grade borosilicate glass bottles with Teflon-coated rubber
stoppers and tamper proof seals. Available bottle sizes:
10 ml, 50 ml, 100 ml, 250 ml Clinical
performance
SpermFilter® and PureSperm have been tested in a
comparative study of 898 ART cycles (245 IUIH, 58 IUI-D and
595 IVF/ICSI cycles). There was no significant difference. (Source:
