Real Customer Feedback

“I work in a small-scale chemical lab and have tested dozens of blunt needles over the years. The 18G-W stands out because it never leaks at the hub and the blunt tip glides easily into rubber septa without coring. Honestly, the only minor issue is that the cap can be a bit tight to remove at first, but that also ensures sterility. I recommend these to anyone needing a dependable dispensing needle.”
