Furthermore, by pulling the plunger back a few times, you can ensure a smooth and consistent flow of medication into the syringe. Thanks, Cool. When using sterile syringes, ensure that there is no contamination, as any contamination can result in serious health complications. This decrease in volume (less space) increases the pressure (more collisions). The first fixing member is a fixed member that is attached to the hub and is used to connect the hub to the elongate tubes diastase. A lead screw, threaded through a pusher block, precisely turns the pumps stepper motor. Never force the plunger as this can cause the barrel to crack or This is a stiff but very fine wire which can be pushed up the needle to clear the blockage. All that is needed is a clean, sharp needle, a small tube (such as a piece of tubing from a pen), and some type of lubricant. For the calculation of the velocity $v_2$: $v_2 =$ (volume of liquid in the syringe)/(time to empty the syringe)/(Area of the needle inner diameter). If both the needle and the syringe are used, it is critical that both be discarded. I'm currently working on a precise glue/resin dispenser, and I'm trying to derive an equation for the force one must exert on a syringe plunger as a function of the desired flow rate Q, and also accounting for the fluid viscosity and the syringe barrel and needle geometry. This plunger is exclusively for 0.5 - 5 L volume 7000 series syringes. Plastic is the most common type of plunger material.
