Using imperial thread, these coated needles are simple, effective, and designed for patient comfort. These needles have a special coating, which decreases friction, allowing the needle to slide in after puncturing the skin, without causing excess trauma or discomfort. Similarly, the triple-bevel lancet design allows for easy puncturing, and reduces the risk of coring. These needles have a hub design which accepts wider tolerances of thread from various makes of cartridge syringe, and are made using imperial thread.
Coring is when a needle punctures a rubber lid and a piece of rubber gets stuck in the core of the needle.
Solo needles are colour coded, with yellow being long, red being short.
