Pasco Burette 50 Buret  (50 mL)

A Borosilicate Glass Burette 50ML With Rotaflow Stopcock is a laboratory instrument used for precise measurement and dispensing of liquids. It consists of a glass tube with volume markings and a rotating stopcock at the bottom that allows for controlled flow of liquid. The glass tube is made of borosilicate glass, a type of glass with low coefficient of thermal expansion, high resistance to thermal shock, and excellent chemical resistance. This makes it ideal for use in laboratory settings where precise measurements and chemical compatibility are crucial. The rotaflow stopcock is made up of a rotating disk with a small opening that can be aligned with the tube to allow for liquid flow or rotated to block the tube and stop the flow. This mechanism is commonly used in titrations, where precise addition of a reagent to a sample is necessary. Overall, the borosilicate burette with rotaflow stopcock is a high-precision instrument commonly used in analytical chemistry, biochemistry, and pharmaceutical laboratories.
