This type of needles is convenient to use for quick blood collection in vacuum tubes, if repeated delayed blood collection is not expected. For example, a surgeon or cosmetologist plans to centrifuge two batches of tubes: first 6 tubes and an hour later another 6 tubes. In this case, it is convenient to use butterfly needles with the ability to fix them on the skin with a bandage, this eliminates the need for repeated vein puncture.
The tube holder is not included.
