Just a quick question to clear up my confusion:

So what is the difference between Luer lock and Luer slip syringes? I understand one stays "locked" in place and the other can be pulled straight off. Is one better than the other? Can you use the same needles for both or does each type of syringe require a certain needle type?

I already have both 18g and 25g needles but the syringes that came with did not fit on. The needles were BD and syringes were Excel, although I did order BD. I believe my previous cycle I used BD "slip" syringes and needles without problems. Thanks.
