Syringes One of the easiest ways of measuring out small quantities of plant foods and boosters is to use a syringe with accurate volume markings. How Syringes Work Syringes are sma ll nozzle ended plastic tubes containing rubber-ended plungers. The tubes have markings for accurate measurement. When the nozzle end is placed in a liquid and the plunger is pulled out, the syringe will suck the liquid into the tube and the markings show how much liquid has been drawn out. The nozzle end of the syringe can then be taken out of the liquid and the surface tension in the nozzle will retain the liquid inside the tube, preventing it from dripping out. The measured amount of liquid can then be added to a reservoir by simply pressing the rubber-ended plunger back down. To see our full Beakers, Jugs, Syringes & Pipettes range, click here Show more
