The BD syringe contains a transparent cylinder that allows a good visualization of the contents. They also have a black graduated scale, very useful for a correct dosage of the drug. The internal siliconization guarantees smoothness in sliding and precise control in aspiration and application of medication. The Luer-Lok™ nozzle (double thread) prevents the needle from accidentally detaching from the syringe. There is no possibility of the plunger detaching from the cylinder due to the special retaining ring. The product is free of natural rubber latex. It is sterile and disposable. The syringe has a capacity of 50ml and each package contains 60 pieces.
