D5 1/2NS 5% dextrose in half amount of normal saline (0.45% w/v of NaCl). [10] D5LR (5% dextrose in lactated Ringer solution) D50 – 50% dextrose in water; The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass ...
Balanced salt solutions are used for washing tissues and cells and are usually combined with other agents to treat the tissues and cells. They provide the cells with water and inorganic ions, while maintaining a physiological pH and osmotic pressure. [2] Sometimes glucose is added as an energy source and phenol red is used as a pH indicator.

Ringer's lactate solution (RL), also known as sodium lactate solution, Lactated Ringer's (LR), and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. [1] It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. [2]
There are many different ways to prepare PBS solutions, common ones are Dulbecco's phosphate-buffered saline (DPBS) [2] and the Cold Spring Harbor protocol. [3] Some formulations of DPBS do not contain potassium and magnesium, while other ones contain calcium and/or magnesium (depending on whether or not the buffer is used on live or fixed tissue: the latter does not require CaCl 2 or MgCl 2).
Preshave products and some shave creams contain potassium hydroxide to force open the hair cuticle and to act as a hygroscopic agent to attract and force water into the hair shaft, causing further damage to the hair. In this weakened state, the hair is more easily cut by a razor blade. Potassium hydroxide is used to identify some species of ...
Benedict's quantitative reagent contains potassium thiocyanate and is used to quantitatively determine the concentration of reducing sugars. [2] This solution forms a copper thiocyanate precipitate which is white and can be used in titration. The titration should be repeated with 1% glucose solution instead of the sample for calibration.
p-chloro-o-benzylphenol, 5–6%; antiseptic; o-phenylphenol, 0.1%; antiseptic; in use circa 1980s; potassium hydroxide, 3–4% Potassium hydroxide is a highly corrosive chemical when used at higher concentrations. It is primarily dangerous to eyes, skin, respiratory tract, and gastrointestinal tract.
