These small disposable vials of deionized water are perfect for moistening biological samples before collection. Each unit is individually packaged and holds 5ml of water—enough for collecting nearly any sample. Simply twist the end off and the water will slowly drip out the end. Once used, it may be disposed of so there is no risk of cross contamination. Contains 100 individually wrapped 5ml packets of water.
