Serological pipettes are suitable for accurate handling of human biological fluids and their transfer from one vessel to another to carry out reactions and facilitate subsequent in Vitro analysis of the sample. The serological pipettes are also recommended for use in hospitals and laboratories (biochemistry, immunology, microbiology, serology, etc.). These single-use pipettes are made of crystal polystyrene and have an accuracy above 98%. They are created in one piece and ensure maximum accuracy without fluid retention at the weld. They provide a complete dispending and are sterilized by radiation. Available volumes from 1 ml to 50 ml, indentified by a cotton coloured and braided. Black graduations and double inverted scale (ascending and descending graduations) for pipettes of 5, 10 and 25 ml.
