A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa.Its pH changes very little when a small amount of strong acid or base is added to it. Nutrifill is a preservative free lens insertion solution specifically designed for scleral lens wearers and the wearers of hybrid and gas permeable contact lenses. It has been physiologically formulated to mimic your body’s natural tears. Contains: sodium, phosphate, potassium, calcium, and magnesium. All essential ions found in our tears. Jan 28, 2019 · PBS or phosphate-buffered saline is a buffer solution that is particularly valuable because it mimic the ion concentration, osmolarity, and pH of human body fluids. In other words, it's isotonic to human solutions, so it's less likely to cause cell damage, toxicity, or unwanted precipitation in biological, medical, or biochemical research. ScleralFil preservative free saline solution – indicated as a scleral lens insertion solution – is an alternative for rinsing and inserting scleral lenses.
