The Dynarex SecureSafe Allergy Safety Syringe Trays provide a sterile, effective way to deliver small doses of medication accurately. The thin wall needles have a double bevel, allowing for ease of penetration while reducing the required plunger force, helping larger doses flow smoothly. The SecureSafe safety engineered mechanism features a cylinder safety cover to conceal the needle, that is activated with a quick pull and twist movement.
