Density Gradient Media (40%, 80%, and 100%)

Description

Density Gradient Media is a ready-to-use, premium solution consisting of silica particles coated with hydrophilic silane, suspended in a balanced salt solution designed to separate highly motile spermatozoa from seminal plasma. Engineered for intrauterine insemination (IUI) and modern andrology workflows, this media exploits cellular density differences to effectively isolate and purify premium-grade, highly functional motile sperm from raw semen samples.

Our premium Density Gradient Media provides a highly efficient, biosafe method for processing raw semen ejaculates within Assisted Reproductive Technology (ART) and andrology laboratories. The formulation features high-purity silica particles coated with hydrophilic silane, suspended inside a protective, dual-acting HEPES/Phosphate buffered balanced salt solution. This specialized matrix establishes distinct density boundaries during centrifugation, allowing laboratory technicians to flawlessly separate cells based on their unique physical densities.

During density gradient centrifugation, the medium securely traps immotile sperm, white blood cells, and dead cellular debris within the upper density layers. Meanwhile, highly motile, morphologically healthy spermatozoa successfully migrate through the gradient boundaries to form a clean pellet at the base of the tube. Its primary clinical application is the isolation and purification of premium-grade, highly functional motile sperm from raw semen ejaculate prior to insemination.

To optimize laboratory workflows, the media is supplied as a ready-to-use solution packed in robust, clear bulk square bottles capped with a highly secure white seal closure. Offered in dedicated concentrations of 40% silica gel concentration (ideal for upper solution layering), 80% silica gel concentration (ideal for lower solution layering), and 100% stock solution concentrations, it allows clinics to easily create customized multi-layer gradients tailored to specific patient requirements.
