These syringes are designed to dispense volumes below 5 μL. This requires an extremely small tungsten plunger wire that travels to the tip of the needle. The resulting design has zero dead volume and is accurate below 50 nL. The 7000 series syringe is used for dispensing minute liquid volumes and features a Modified Microliter design. The series employs a plunger wire inside the needle to accurately dispense ultra-low volumes. The needle is bored to extremely accurate tolerances to accommodate the plunger wire. With the plunger inside the needle, the standard dead volume inside the needle is eliminated.
