1.Made of highquality, corrosionresistant rubber: our Peleus ball is made of highquality, corrosionresistant rubber, which is durable and to use. It ensures reliable performance for precise fluid absorption in your lab 2.Three openings for compactness: the pipette filler is a practical tool that makes the use of pipettes easier and more efficient. With three openings and elastic rubber force, it helps to pull liquids quickly and precisely 3.Principle of work: each opening of the pipette ball has a small ball of rubber hose, as long as you press the side of the ball can be discharged between the small ball and the rubber hose gap between the air, you can form a gap between the air and the outside world 4.VERSATILE: Laboratory pipette dispensers are used in conjunction with pipettes to control the inflow and outflow of pipette contents. Our pipette fertilisers ensure quick and liquid absorption and are ideal for use in chemical and science laboratories
