250pcs Black Barrel Plug Dispensing Needle Tip Caps Ink Oral Cap Lock Needle Caps Cap Clear Cap on Lock Tip Cap Plastic Black Bucket

I have a bunch of both luer lock and luer slip syringes. I have caps for the luer slip syringes, but they don't work for luer lock ones. This pack gives me plenty and I don't have to worry about running out anytime soon. Plus, luer lock caps also work just fine on luer slip syringes. It's basically killing two birds with one stone in this case. They aren't sterile, but for my needs I don't need them to be so long as they are clean enough. If you need to sterilize them, you could drop them into an ultrasonic cleaner, or some rubbing alcohol if you don't have a cleaner.

Loved the price and the amount it comes with! I ordered these screw caps for my syringes so I could turn my PRP serum into PRP gel and the machine to do that requires the syringes to had lids and these literally worked PERFECTLY I am beyond happy and satisfied with these! They did just fine with high and low temperature settings as well and gave me no issues.
