• To prepare semen for cryopreservation. Concentration of stallion sperm is often needed for the sperm cryopreservation procedure. Cushioned centrifugation is the most common procedure used, but this process can cause deleterious effects, including reduction in sperm quality as well as loss of sperm numbers and agglutination. Therefore SpermFilter®, a new technology, has been developed. The filter is made up by a hydrophilic synthetic membrane and has shown it’s efficiency to concentrate stallion sperm. SpermFilter® allows retrieval of almost all sperm from the original sample without causing any damage.
• To prepare semen for EquiPure™ treatment. Concentrating the sperm prior to EquiPure™ treatment is needed for samples with low sperm concentration. SpermFilter® is ideal in combination with EquiPure™. SpermFilter® concentrates and EquiPure™ purifies.
• Gentle treatment of poor-quality, low concentration semen samples. The SpermFilter®-technique is especially useful with semen of poor quality, for separating sperm from seminal plasma, and/or extender, concentrating sperm for freezing and cooling or for EquiPure™ centrifugation to concentrate sperm for low doses AI.
• Avoids sperm agglutination. Cushioned centrifugation tends to cause sperm agglutination. Low concentration samples are often low quality samples and are more prone to agglutinate. SpermFilter® is a more suitable option for these samples.
• Re-usable after washing. You can re-use the SpermFilter® up to 10 times for the same stallion.
• Quick and simple. It is a one-step procedure that only takes minutes.
• No additional equipment needed. No extra equipment is needed. You only need the supplied Petri dish and SpermFilter®.
