Filling a luer lock syringe, particularly for applications like needle-free injections, involves a simple process of twisting and securing. Here's how:
-
Overfill: According to the YouTube video by National Medical Products, Inc., even though the syringe may have a maximum fill line (e.g., 0.25), you can overfill it slightly to facilitate the attachment of the syringe to the J-Tip or other Luer Lock compatible devices.
-
Attach: Twist the syringe onto the front of the receiving port (e.g., a J-Tip).
-
Secure: After initially twisting the syringe on, give it an extra turn to ensure a nice, tight, and secure seal. This prevents leakage and ensures proper functionality during use.
