SPERMCARE Lower Layer - Gradient System is a 90% solution of silane-coated silica particles in Earle's Balanced Salts Solution (EBSS) with HEPES (pH buffer). Available in 45%, 90% and 100%. SPERMCARE Lower Layer - Gradient System is used for separation and purification of human sperm for assisted reproduction procedures. SPERM WASH MEDIUM is a synthetic, defined culture medium supplemented with 5mg/ml human serum albumin and is intended for use in assisted reproductive technology procedures. It has been formulated to mimic the composition of the fluid found in fallopian tubes as defined by Quinn etal (Quinn P, Kerin JF, Warnes GM: Fertil Steril 1985;44:493-498). SPERM WASH MEDIUM uses a combined sodium bicarbonate/HEPES ([4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid]) buffering system and is appropriate for those procedures that do not use a carbon dioxide atmosphere.
A solution that provides a physiological environment for the retrieval, culture, maintenance, transfer, and/or storage of human sperm, harvested oocytes (eggs), and/or resulting embryos associated with the method of in vitro fertilization (IVF). The solution typically contains various combinations of salts, carbohydrates, amino acids, enzymes, hormones, albumin, vitamins, and/or drugs (e.g., antibiotics). This is a single-use device.
